Spencer Grill & RV Park

Spencer Grill & RV Park in Spencer, Idaho, offers full-hookup back-in RV sites with water, sewer, and electric alongside an on-site grill, directly on the I-15 corridor near the Montana border. Open all year at nearly 5,300 feet on the northeastern margin of the Snake River Plain. Full-hookup back-in sites carry water, sewer, and electric. The grill is the distinguishing feature — a genuine meal without leaving the property, which matters more than it sounds in a county this sparsely populated. The park operates year-round. Pets are welcome. The amenity set is deliberately minimal, and the proposition is straightforward: reliable hookups, hot food, and a place to stop on one of the Northern Rockies' primary north-south interstate corridors. In a landscape where the next services can be a long way off, hospitality and fuel infrastructure carry real value for passing travelers. Spencer sits in Clark County on the high volcanic plain, in one of Idaho's most sparsely populated counties. The landscape was shaped by ancient volcanic events and is characterized by a remoteness that defines the drive — the town is best known for its opal mines, among the few public opal digging sites in the United States. The park serves I-15 traffic year-round, with summer bringing the heaviest flow of travelers heading toward Yellowstone and the Montana border and winter drawing a steadier trickle of long-haul traffic. The year-round operation is worth noting at this elevation, where many small parks close for the season.
