Lost Trail

20 RV Sites

Nestled along the Portneuf River in Lava Hot Springs, Idaho—in the Gem State's southeastern corner where the basalt lava flows of the Snake River Plain meet the limestone canyons of the Portneuf drainage and the geothermal activity that the region's volcanic geology produces flows to the surface in the world-famous hot springs that gave the town its identity—Lost Trail Resort provides full hookup RV sites on the Portneuf riverbank, pull-through options, and on-site motel rooms and cabins in the most geographically immediate position to Lava Hot Springs' natural geothermal pools that any campground in the area offers. Mountains rising on one side of the property, the Portneuf River on the other, and the town's geothermal infrastructure within walking distance create the specific combination that makes a Lava Hot Springs stay categorically different from any campground that merely approximates the hot springs experience. Full hookup RV sites with riverbank positioning accommodate the range of RV configurations, with pull-through options available for guests arriving with large rigs or who prefer not to back into a riverside site. The family-owned property maintains modern facilities including free WiFi, clean bathrooms, pet-friendly accommodations, and air conditioning. Motel rooms serve the guests traveling without RVs, and cabin accommodations provide the enclosed alternative with private amenities. The Portneuf River flowing beside the property provides the natural sound and visual environment that riverside camping specifically offers—and in Lava Hot Springs, where the river's geothermal character gives the water a warmth unusual for a mountain stream, the riverbank itself carries a specific ambient temperature that guests notice immediately on cool Idaho mornings. Lava Hot Springs' geothermal pools are the resource that organizes the entire visitor experience of this southeastern Idaho town. The Idaho Department of Parks and Recreation operates the geothermal complex—maintained at no cost to the state beyond its own revenue—as a public facility with soaking pools maintained at multiple temperatures from 102 to 112 degrees Fahrenheit, fed continuously by the natural spring flow. The pools have operated continuously since the Shoshone-Bannock people first used the springs, were developed as a commercial resort in the late 19th century, and have maintained their public-ownership status through the 20th century and into the present as one of the only state-operated geothermal public bathing facilities in the American West. The Olympic-standard outdoor swimming complex—a separate facility from the hot soaking pools, operated by the same parks authority, open in summer—provides a 50-meter lap pool, diving platforms, and water slides in a facility built to Olympic specification that serves the competitive swimming market alongside the recreational swimming population that the Lava Hot Springs summer economy depends on. Year-round access to the geothermal soaking pools alongside summer-only access to the swimming complex creates the visitor calendar that makes Lava Hot Springs genuinely functional as a destination in every season. Hiking access to the surrounding Caribou-Targhee National Forest terrain, fishing in the Portneuf River system, and the winter sports available in the surrounding southeastern Idaho mountains extend the outdoor programming. Lost Trail Resort is open year-round in alignment with Lava Hot Springs' year-round geothermal pool access. The summer swimming complex season—from Memorial Day through Labor Day—drives peak demand. Winter soaking season draws the guests who specifically seek a geothermal pool experience in cold weather, when the temperature contrast between the 100-plus-degree water and the freezing air produces the atmospheric steam that makes hot spring bathing in cold conditions its most viscerally satisfying. Reserve your riverbank site early for summer and let Lava Hot Springs' natural geothermal infrastructure earn its place as southeastern Idaho's most irreplaceable visitor experience.

Aspen Grove RV Park

48 RV Sites

Aspen Grove RV Park occupies a well-developed property in Tremonton, Utah, at the intersection of Interstate 15 and Interstate 84 in Box Elder County—one of the most strategically positioned campgrounds in northern Utah for travelers crossing between Salt Lake City, Boise, and the Great Basin destinations that converge on this corner of the state. The park's 54 sites are built for modern RV travel, with full hookups, EV charging at individual sites, big-rig-friendly pull-throughs, and a clubhouse capable of hosting groups up to 80 guests in a region where quality private RV infrastructure has historically been limited. All 54 sites include electricity, water, sewer, and WiFi, with onsite laundry and shower and bathroom facilities providing the daily practical amenities. EV charging at individual sites is a forward-looking infrastructure choice that distinguishes Aspen Grove from most campgrounds in northern Utah. A sports court, playground, cornhole, horseshoes, and ladder-ball serve the recreational needs of families and groups, and a fenced dog park accommodates traveling pets. The clubhouse with its full kitchen and lounge area makes the park capable of hosting private events, family reunions, and group camping gatherings that most campgrounds cannot accommodate properly. The park has earned consistently high ratings from Good Sam and independent review sites for its cleanliness and customer service. Tremonton sits in Box Elder County's Cache Valley corridor, where the mountains of the Wellsville Range rise to the east and the flats of the Great Salt Lake basin stretch west toward the lake's northern arm. The agricultural character of the valley—sugar beets, wheat, and livestock operations that reflect Cache Valley's history as one of Utah's most productive farming regions—gives Tremonton a working rural character that distinguishes it from the ski resort towns and national park gateway communities that define much of Utah's tourism identity. Crystal Hot Springs, just south of Tremonton, provides natural geothermal soaking pools and a waterpark facility fed by the same artesian springs that have attracted visitors to this valley since the nineteenth century. The Bear River Migratory Bird Refuge, located just south of Brigham City along the Great Salt Lake's northeastern shore, is one of the most important shorebird migration staging areas in the Western Hemisphere—the refuge's freshwater marshes at the mouth of the Bear River provide habitat for millions of birds during the spring and fall migrations, including white pelicans, tundra swans, and over 200 species of shorebird in a single season. Willard Bay State Park provides warm-water boating and fishing on a freshwater reservoir just south of Tremonton. The Spiral Jetty, Robert Smithson's iconic earthwork spiraling into the Great Salt Lake from the Rozel Point shore, is accessible as a day trip for art and landscape travelers. Bear Lake, about an hour northeast, offers turquoise water comparable to the Caribbean in a mountain valley setting that provides swimming, paddleboarding, and boating. Aspen Grove RV Park operates year-round as a northern Utah corridor stop and destination campground, with summer bringing peak demand from I-15 and I-84 travelers and the shoulder seasons from April through June and September through October delivering comfortable conditions for visiting the Bear River refuge, Crystal Hot Springs, and the broader Box Elder County outdoor landscape. The park's modern infrastructure and central location make it equally useful as an overnight stop between Salt Lake City and Boise and as a base for multi-day exploration of northern Utah's underappreciated lake, refuge, and mountain terrain.

Sun Outdoors Garden City Utah

163 RV Sites, 2 Cabins, 5 Tent Sites, 36 Hotel Rooms

Sun Outdoors Garden City in Utah offers 163 full-hookup RV sites, 38 cabin and hotel room units, and five tent sites on the western shore of Bear Lake, with 30 and 50-amp service and rigs accepted to 45 feet, open all year. Standard back-in, pull-in, and pull-through categories join a pool, hot tub, spa, beach, and boat docks. One hundred sixty-three sites run in standard back-in, standard pull-in, and standard pull-through categories, all carrying water, sewer, and electric on 30 and 50-amp with site WiFi, sized to 45 feet, with picnic tables. Three straightforward categories keep booking simple. Thirty-eight cabins and hotel rooms and five tent sites round out the lodging. A general store, laundry, propane fills and exchange, dump station, restrooms, and showers handle the practical side. The property was formerly Blue Water RV Resort. An outdoor pool, hot tub, sauna, and spa anchor the property, with a beach and boat docks opening the lake for boating and swimming. A recreation center, craft room, sports courts, pickleball, basketball, a playground, pavilion, and community fire pit fill the rest, with skiing, a state park, and mountains nearby and productive birding along the shore. The address is 2126 South Bear Lake Boulevard, eight miles south of the Idaho border. Bear Lake's water is a startling turquoise — the result of suspended limestone — which makes it one of the most visually distinctive lakes in the Intermountain West, framed by Wasatch-Cache ridges on three sides. Summer is the short, intense season at Bear Lake, with the raspberry harvest drawing August crowds. Reserve well ahead.

Idaho Falls Luxury RV Park

Idaho Falls Luxury RV Park occupies a site with genuine history along the Snake River in eastern Idaho — built on the grounds of the former Sky-Vu Drive-In Theater, a local landmark established in 1950 that brought families together for decades before closing. When the Teichert and Sebastian families acquired the site in 2021 and opened the park in May 2023, they channeled that family-gathering legacy into an RV destination built to a standard rarely seen in the region, with oversized spaces and resort-quality amenities that together form the largest and most polished full-hookup park in East Idaho. Sites here rank among the most spacious in the region — designed to accommodate today's largest motorhomes and fifth wheels with the clearances that guests traveling in 40-foot rigs genuinely require. Direct access to the Snake River and the paved Greenbelt trail system opens the park's outdoor recreation to both walkers and cyclists, with free bike rentals available on-site for guests who arrive without their own. Two pickleball courts, a dedicated dog park, a playground, site-specific Wi-Fi at every pad, and the region's largest outdoor community fireplace round out an amenity lineup built to rival what high-end home communities offer rather than what campgrounds typically provide. Full hookups with 30- and 50-amp service and modern bathhouse facilities complete the practical infrastructure. The Snake River corridor through Idaho Falls gives the park an exceptionally attractive natural setting for a city-adjacent campground — the Greenbelt's tree-lined path traces the river for miles in both directions, and the sound of moving water provides a constant ambient backdrop that softens the urban context. The city of Idaho Falls itself is a pleasant mid-sized community with a lively downtown riverfront, the Idaho Falls Idaho Temple, and a growing dining and arts scene that rewards an evening stroll from camp. The Museum of Idaho in downtown Idaho Falls covers the natural and human history of the region comprehensively, and its rotating exhibits frequently draw visitors who weren't planning a museum day. Yellowstone National Park is roughly two and a half hours north — a long day trip from Idaho Falls that most guests make at least once during an extended stay. Grand Teton National Park is about 90 minutes away, offering what many consider the most dramatic mountain scenery accessible by paved road in the lower 48. Craters of the Moon National Monument, 90 minutes west, provides a lunar lava-field landscape that is one of the more surprising natural experiences in the American West. Idaho Falls Luxury RV Park operates year-round, with summer and fall the most popular seasons for regional park and monument touring. The Snake River's seasonal flow and the Greenbelt's condition vary through the year, with spring and early summer typically the most lush and photogenic for riverside walking and cycling. Reserve early for summer stays when Yellowstone and Grand Teton traffic drives demand across all eastern Idaho campgrounds — the park's combination of large sites, full hookups, and city proximity makes it a consistent first choice for guests with more discerning RV accommodation standards.

Valley View RV Resort

127 RV Sites

Valley View RV Resort in Layton, Utah, offers 127 full-hookup RV sites with 20, 30, and 50-amp service and rigs accepted to 90 feet on a big-rig-friendly layout. Six categories cover back-in, perimeter back-in, pull-in, and pull-through in standard and premium, with a pool, hot tub, fitness center, and pickleball on the Wasatch Front. One hundred twenty-seven sites span back-in, perimeter back-in, pull-in, premium pull-in, pull-through, and premium pull-through categories, all carrying water, sewer, and electric on 20, 30, and 50-amp, sized to 90 feet, with site WiFi. Two practical notes from the resort: some sites have minor side-to-side slope, and you should use Google Maps to find the property — other mapping services do not locate it reliably. A laundry, propane fills, restrooms, and showers handle the practical side. An outdoor pool and hot tub and sauna anchor the property, with a fitness center, clubhouse, recreation center, and game room covering the rest. Pickleball, a pond, community fire pit, playground, dog park, pavilion, and on-site dining fill the grounds. Skiing and snowboarding are nearby. Pets are welcome. Layton sits in Davis County just north of Salt Lake City, where the Great Salt Lake's eastern shore meets the Wasatch Range. The canyon access is the advantage — world-class skiing in winter, hiking and mountain biking in summer, all within minutes of the valley floor. Ski season and summer mountain recreation both drive demand. Reserve ahead for winter weekends.

Aspen Grove Inn at Heise Bridge

30 RV Sites, 6 Cabins, 11 Tent Sites, 4 Cottages, 2 Yurts, 1 Onsite RV/Trailer, 1 House

Aspen Grove Inn at Heise Bridge in Rigby, Idaho, offers year-round accommodations in eastern Idaho's Snake River Plain — RV and camp sites, cabins, private cottages, yurts, glamper campers, and a lodge with bunkhouse giving guests a comprehensive range of lodging options in Jefferson County's agricultural and outdoor recreation landscape between Idaho Falls and the Teton Valley. The property's year-round operation and accommodation diversity serve the full spectrum of eastern Idaho visitors: fly fishing and float trip guests on the Henry's Fork and South Fork of the Snake River, Yellowstone National Park travelers using Idaho Falls as their western park approach, and the regional outdoor recreation community pursuing the Snake River Plain's volcanic geology and the surrounding public land network. RV sites with hookups, tent camping, cabins, cottages, yurts, glamper campers, and the lodge and bunkhouse give the property the most comprehensive accommodation range of any camping property in eastern Idaho — a flexibility that serves solo anglers, family groups, corporate retreat groups, and outdoor organizations whose equipment and accommodation needs span the full range that a property of this accommodation depth can address. The year-round operation maintains availability through the winter months when the surrounding Snake River Plain's fishing and wildlife activity continues in modified form from the summer peak. Pets are welcome. The Henry's Fork of the Snake River, flowing south from Henry's Lake through Island Park and the Mesa Falls corridor toward Ashton, is one of the most famous spring creek dry-fly fisheries in the world — the Railroad Ranch section through the Harriman State Park meadow, where rainbow trout of 18 to 24 inches rise in spring creek-style feeding lanes to mayfly and caddis hatches that the Henry's Fork's cold, clear spring flow sustains, is specifically cited in international fly fishing literature as a standard of difficult, technical, demanding trout fishing. The South Fork of the Snake River through the Swan Valley provides the float fishing complement — a large, productive freestone river where the rainbow and cutthroat trout populations support a guide industry of significant regional scale. Yellowstone National Park, approximately 90 miles north and east via the US Highway 20 and State Highway 47 Island Park corridor, gives Rigby the western approach to the park that avoids the congested South Entrance from Jackson Hole — a less-traveled approach through Island Park's volcanic caldera and the Ashton-Flagg Ranch Road into the park's Bechler and Falls River country in the park's southwestern quadrant. The Grand Teton National Park's western Snake River approach from Victor, Idaho, over the Teton Pass, provides the additional mountain scenery corridor accessible from the eastern Idaho base. Aspen Grove Inn at Heise Bridge operates year-round in eastern Idaho's continental climate, where the summer season from June through September provides the peak fly fishing, Yellowstone touring, and outdoor recreation activity and the winter months offer the specific cold-weather Idaho experience of the Snake River Plain landscape. The Ririe Reservoir, immediately west of Rigby, provides motorized water recreation, fishing, and the Tex Creek Wildlife Management Area's hunting access for the eastern Idaho visitor base. Reserve cabins, cottages, and lodge accommodations ahead for the peak summer fly fishing season when the Henry's Fork and South Fork guide bookings fill months in advance and overnight accommodation in Jefferson County fills from the regional fishing and Yellowstone travel market.

Idaho Sky RV Resort

144 RV Sites, 1 Cabin

In Rexburg, Idaho—in Madison County on the Snake River Plain of eastern Idaho where the Teton Range's volcanic peaks rise 60 miles to the east, the Yellowstone caldera lies 90 minutes northeast, and the St. Anthony Sand Dunes' desert landscape contrasts spectacularly with the irrigated agricultural plain of the upper Snake River Valley—Idaho Sky RV Resort offers 159 large full hookup sites with pull-throughs reaching 89 feet by 40 feet, vacation rental accommodations, two hot tubs, pickleball courts, 24-hour laundry, complimentary WiFi, BBQ grills and community fire pits in a premier eastern Idaho resort that serves as the most practical and comfortable gateway campground for the Yellowstone-Teton corridor that makes this part of Idaho one of the most spectacular natural environments accessible by road anywhere in the continental United States. For Yellowstone and Grand Teton visitors who want a full-service resort rather than a national park campground lottery, Rexburg solves the problem. The 159 full hookup sites include pull-throughs at 89 by 40 feet and smaller options at 62 by 35 feet, accommodating the full range of rigs the Yellowstone circuit attracts—from 45-foot motorhomes to family travel trailers—with 30 and 50-amp service on every site. Two hot tubs provide the mineral soak recovery that the day's hiking in the Tetons or exploring Yellowstone's geyser basins genuinely demands, pickleball courts serve the active resort community, and the 24-hour laundry ensures that multi-week Yellowstone-circuit travelers can maintain clean wardrobes without disrupting the exploration schedule. Vacation rental accommodations provide the furnished option for guests traveling without an RV. BBQ grills and fire pits create the outdoor gathering space that summer evenings in eastern Idaho's clear mountain air invite. Rexburg sits in Madison County at 4,865 feet on the Snake River Plain, where irrigation has transformed high-desert sage into the potato and grain production that drives the county's economy. BYU-Idaho's campus gives Rexburg its college-town character, and the city's position as the eastern Idaho hub for the Yellowstone-Teton corridor creates the service economy the resort serves. Grand Teton National Park, 60 miles east via US-20 and US-26 through Driggs, provides the full Teton mountain experience—the Cathedral Group's 13,770-foot Grand Teton, Jenny Lake, the String Lake swimming, the valley floor moose and bison that the park manages, and the Snake River float trips from Jackson Lake to Moose that expose the Teton skyline from the water. Yellowstone National Park, 90 miles northeast via US-20 through Ashton and the Marysville Road, provides the geothermal world of Old Faithful, the Grand Prismatic Spring, the Lamar Valley's wolf and bison populations, and the Yellowstone Falls that make the park the most geologically extraordinary landscape in North America. Harriman State Park, 30 miles north near Ashton on the Henry's Fork of the Snake River, protects one of the most productive wild trout fisheries in the Rocky Mountains. Idaho Sky RV Resort operates year-round in Rexburg's eastern Idaho climate, with the primary Yellowstone-Teton season running from Memorial Day through September when the parks are fully accessible and the eastern Idaho mountain weather at its most reliable. The St. Anthony Sand Dunes—expansive white quartz sand dunes 30 miles north—provide the off-season recreation for OHV and sandboarding enthusiasts during the shoulder seasons. Fall in the Teton Valley from September through October delivers the golden aspen groves against the Teton skyline in one of the Rocky Mountain West's most photographed autumn landscapes. Reserve your site at Idaho Sky RV Resort and let Rexburg's proximity to Yellowstone, the Tetons, and the Snake River Plain's extraordinary eastern Idaho landscape make this the gateway resort your western adventure requires.

Sun Outdoors Salt Lake City

148 RV Sites, 29 Cottages

Sun Outdoors Salt Lake City in North Salt Lake offers 148 RV sites and 29 cottages seven miles from downtown, with 30 and 50-amp full hookups, cable TV, and rigs accepted to 70 feet on a big-rig-friendly layout. Five tiered categories run from standard back-in through Deluxe, Deluxe Plus, Premium, and Executive pull-throughs, behind a gated entrance and open all year. One hundred forty-eight sites span standard back-in and Deluxe, Deluxe Plus, Premium, and Executive pull-through categories, all carrying water, sewer, and electric on 30 and 50-amp with cable TV and site WiFi, sized to 70 feet, with picnic tables. The tiering makes it straightforward to match site quality to budget. Twenty-nine cottages and Airstream rentals serve guests without a rig. A general store, laundry, propane fills and exchange, dump station, restrooms, and showers handle the practical side. The property was formerly Pony Express RV Resort. An outdoor pool anchors the summer, with a clubhouse, recreation center, game room, library, and billiards for other hours. Sports courts, basketball, corn hole, walking trails, a playground, and a dog park fill the grounds, with life-size chess and checkers in the common areas and a community fire pit for evenings. Hiking, biking, skiing, and snowboarding are all nearby. Pets are welcome. The position is the leverage. Downtown Salt Lake, Temple Square, the Natural History Museum, and world-class skiing are minutes away, and the resort sits roughly between Zion and Yellowstone for road-trip planning. Open year-round, with summer national park traffic and winter ski season both driving demand. Reserve ahead for either.

Sugar City RV Park

27 RV Sites

In Sugar City, Idaho—in Madison County on the Snake River Plain of eastern Idaho, minutes from Rexburg and positioned at the gateway to some of the most spectacular natural environments accessible by road in the continental United States—Sugar City RV Park offers 25 large pull-through sites with full hookups, grass areas, bathrooms, showers, laundry, a dog park, and picnic tables in a clean, straightforward park whose eastern Idaho position puts Yellowstone National Park's west entrance 90 minutes northeast, Grand Teton National Park 60 miles east, the St. Anthony Sand Dunes 30 miles north, and Mesa Falls 35 miles northeast within easy day-trip range of what is among the most scenically endowed campground locations in the Rocky Mountain West. The park is the basecamp. The destination is everything outside it. All 25 sites are large pull-throughs with full hookup service—electric, water, and sewer—with grass areas between the sites that give the property a softer character than the pure gravel pad parks that the agricultural Snake River Plain's other RV options provide. The sites accommodate up to six people, two pets, and two licensed vehicles per site, making them genuinely spacious for the family and extended-party stays that national park corridor campgrounds regularly host. Bathrooms, hot showers, coin laundry, a dog park, and picnic tables complete the essential daily infrastructure for guests who are at Sugar City to sleep, shower, and launch—not to spend their days in the campground. The full hookup standard and the clean, well-maintained facilities create the reliable overnight that a Yellowstone-circuit campground requires. Sugar City occupies Madison County on the Snake River Plain at 4,700 feet in the agricultural landscape of eastern Idaho's potato and grain country, in the community immediately east of Rexburg where BYU-Idaho's campus and the region's agricultural economy create the small-city character that the surrounding Teton, Yellowstone, and Snake River Plain landscapes make genuinely spectacular. The Snake River Plain's volcanic geology—the source of the lava flows, cinder cones, and rift zones that make the eastern Idaho landscape so visually distinctive from the Rocky Mountain terrain to the east and south—creates the geological context that the Craters of the Moon National Monument and Preserve, 100 miles west, documents most dramatically. Grand Teton National Park, 60 miles east via US-20 and US-26 through Driggs and Victor in the Teton Valley, provides the Cathedral Group's iconic skyline—the Grand Teton, Mount Owen, and Teewinot Mountain's vertical granite faces rising directly from the valley floor in the visual drama that makes the Tetons the most photographed mountains in North America. Yellowstone's West Entrance at West Yellowstone, Montana, accessible via US-20 through Island Park, provides the park's most direct access from eastern Idaho—the Grand Loop Road's geyser basins, the Canyon Village and the Yellowstone Falls, and the Lamar Valley's wolf and bison watching accessible from the west entrance in a day of driving and wildlife observation. Sugar City RV Park operates year-round in eastern Idaho's high-plains climate, with the primary Yellowstone-Teton season running from Memorial Day through September when the parks' full facility and road systems are open. The St. Anthony Sand Dunes—the largest accessible white quartz sand dunes in the western United States—provide year-round recreation for OHV enthusiasts and the off-season complement to the national park access that drives most Sugar City summer visitors. Reserve your pull-through site at Sugar City RV Park and let the eastern Idaho Snake River Plain's extraordinary position between Yellowstone, the Tetons, and the sand dunes make this straightforward, clean park the gateway campground your Rocky Mountain road trip deserves.

Jolley Camper RV and Cottages

14 RV Sites, 10 Tent Sites, 3 Cottages

Situated in Ashton, Idaho, in the upper Snake River Plain near the Wyoming border, Jolley Camper RV and Cottages positions guests at the western gateway to Yellowstone National Park's Bechler and Cave Falls areas while also providing a convenient base for the Mesa Falls Scenic Byway, the St. Anthony Sand Dunes, and the volcanic landscapes of eastern Idaho. The campground's site layout on a privacy-oriented loop, combined with Grand Teton views from select RV positions and Idaho sunset panoramas across the plain, gives the property a scenic character that sets it apart from purely utilitarian campgrounds in the Ashton area. Accommodations span three formats to suit different travel preferences. Cottages sleeping up to four are fully equipped with heaters, air conditioning, private bathrooms and showers, refrigerators, microwaves, and coffee makers—a level of self-contained comfort suited to guests who prefer not to manage campground logistics while using the property as a basecamp for multi-day regional exploration. RV hookup sites on the privacy loop provide full connections including water, sewer, and 30-amp electrical service, with select positions oriented toward the Teton Range to the east. Open lawn camping areas with tent-friendly surfaces are available alongside shared restrooms, showers, and laundry access. The upper Snake River Plain landscape surrounding Ashton is geologically dramatic—a volcanic plateau shaped by some of the most recent and extensive basaltic eruptions in the continental United States, with the Yellowstone hotspot's geological influence visible in the cinder cones, lava flows, and thermal features that punctuate the countryside. The Henry's Fork of the Snake River, flowing through the Harriman State Park meadows and through Island Park before passing near Ashton, is one of the most celebrated fly fishing rivers in the American West and draws anglers from across the country during its productive season. Cave Falls and the Bechler Meadows area in Yellowstone National Park's southwest corner are accessible via Forest Service roads from Ashton—a remote and lightly visited section of the park characterized by cascading waterfalls, thermal springs, and extensive backcountry meadows that are often snow-free later in summer than the more famous northern sections. Mesa Falls, accessible on the Mesa Falls Scenic Byway north of Ashton, is among the most visually impressive waterfalls in the Pacific Northwest region, with both Upper Mesa Falls and Lower Mesa Falls viewable from maintained trails in the Targhee National Forest. The St. Anthony Sand Dunes, a field of shifting quartz sand dunes spanning thousands of acres east of St. Anthony, provide off-road vehicle recreation and an unusual high-desert landscape experience. Jolley Camper RV and Cottages is most active during the summer season when Yellowstone and Teton National Park visitation peaks and the regional trail network becomes fully accessible. Advance reservations for cottages and preferred RV positions are recommended for July and August, when eastern Idaho's position between multiple national parks creates high demand for quality basecamp accommodations. The campground's accessible cottage options and RV loop provide a welcoming setup for first-time visitors to eastern Idaho's remarkable concentration of volcanic, wildlife, and wilderness attractions.

Over The Hill RV Park - Hanna

19 RV Sites, 8 Tent Sites, 3 Onsite RV/Trailers

Over The Hill RV Park in Hanna, Utah, offers 22 RV sites and eight tent sites directly along the Duchesne River, with 20 and 30-amp service and rigs accepted to 50 feet on a big-rig-friendly layout. Full-hookup, electric-only, back-in, and pull-through categories are available, plus RV and trailer rentals, with trout fishing from the campsite itself. Twenty-two sites run in 20-amp and 30-amp electric-only back-ins, full-hookup back-ins, and pull-throughs, carrying water, sewer, and electric where noted and sized to 50 feet. Eight tent sites and stationary RV and trailer rentals round out the accommodations. Restrooms and showers are on site. Two seasonal notes worth planning around: the park typically opens May 1, earlier if the weather cooperates, and if October temperatures drop below freezing the water may be shut off — call ahead for late-season stays. The river is the recreation. Trout fishing runs directly from the campsites, with swimming, hiking, birding, basketball, and horseshoes filling the rest. A pavilion suits family reunions and group gatherings, which is much of the park's business. Pets are welcome. Hanna sits in Duchesne County in the high Uinta Basin, where the Duchesne River's upper tributaries drain the southern slopes of the Uinta Mountains through ranching valleys managed by the Ashley Forest District. Starvation Reservoir, the Uinta Mountains' high-lake backcountry, and the ATV trail network around Hanna are all directly accessible — this is the most convenient base for the upper Duchesne drainage. The season runs roughly May through October. Summer fishing and high-country access drive demand, and fall brings quieter conditions before the water shutoff. Reserve ahead for summer weekends.

Red Rock RV Park

137 RV Sites, 1 Tiny House

At the base of Sawtelle Peak in Island Park, Idaho—in Fremont County 22 miles from Yellowstone National Park's West Entrance on the US-20 corridor where the Island Park caldera's volcanic plateau, the Henry's Fork of the Snake River, and the lodgepole pine forest create the most Yellowstone-adjacent landscape accessible outside the park's own boundaries—Red Rock RV Park by Open Road Resorts offers 155 full hookup sites with 20, 30, and 50-amp service, a small number of tent sites, ROAM Deluxe cabins sleeping six with queen beds, twin lofts, a sleeper sofa, and a full kitchen and bath, a boutique retail store, a pickleball court, a large playground, ping pong and foosball tables, a covered patio with a grilling station, a brand-new bathhouse, clean laundry facilities, a dog park, WiFi, and propane fill, in a resort whose 22-mile Yellowstone West Entrance position and Sawtelle Peak backdrop create the most practically located base camp for the Yellowstone-Henry's Fork corridor that Island Park's resort community offers. The park is 22 miles from Yellowstone. The caldera is everywhere. All 155 full hookup sites provide the 20, 30, and 50-amp electric service alongside water and sewer in the level pull-thru and back-in configurations that a 155-site Yellowstone-area resort maintains across the full RV size spectrum. ROAM Deluxe cabins—a queen master bedroom, twin beds in an elevated loft, a sleeper sofa, and a full kitchen and bath—provide the enclosed accommodation alternative for guests without a rig. The boutique retail store, pickleball court, playground, ping pong and foosball tables, and covered patio with grilling station create the on-property recreation that a multi-day Yellowstone base camp requires between park days. The brand-new bathhouse, clean laundry, dog park, WiFi, and propane fill complete the practical daily support. Island Park sits in Fremont County on the Island Park caldera—one of the largest ancient volcanic calderas in North America, 23 miles in diameter, whose collapse created the plateau that the Henry's Fork of the Snake River drains in the meadow-and-forest landscape that Yellowstone's geologic processes extend into the adjacent Idaho terrain. The Henry's Fork, one of the most celebrated dry-fly trout streams in the American West, flows through the Island Park caldera's meadow sections—the Box Canyon and Last Chance sections of the Henry's Fork provide the technical dry-fly fishing that the national fly-fishing community considers benchmark water for the sport. Yellowstone National Park's West Entrance, 22 miles north on US-20, provides access to the park's western geyser basins—the Lower, Midway, and Upper Geyser Basins including Old Faithful, the Grand Prismatic Spring's turquoise and orange thermal pool, and the Firehole River's thermal swimming area—along with the Madison Junction's wolf and bison watching and the Madison River's blue-ribbon trout fishery. Henry's Lake, 8 miles north of Island Park, provides the high-altitude fishing lake whose cutthroat, rainbow, and brook trout populations and the wetland bird habitat surrounding the lake create the immediate recreational alternative to the Yellowstone drive. Red Rock RV Park operates seasonally through the Island Park summer and early fall season, with the June through September window the primary open period and the Yellowstone peak from late June through Labor Day the most attended. The spring wildlife watching season in May, when the Yellowstone bison and pronghorn herds are calving and the migrating waterfowl are passing through the Henry's Fork corridor, provides the wildlife-photography opportunity that the off-peak visitor pursues before the summer crowds arrive. Reserve your full hookup site or ROAM cabin at Red Rock RV Park and let the 22-mile Yellowstone access, the Henry's Fork fishing, and the Island Park caldera's extraordinary landscape deliver the Yellowstone gateway stay that the park's most productive western corridor provides.
