Onion River Campground

Onion River Campground in Plainfield, Vermont, offers 26 RV sites and 24 tent sites along the Winooski River, with 30 and 50-amp service and rigs accepted to 25 feet. Full-hookup and water-and-electric back-in categories at both amperages join walking trails, a community fire pit, and forested grounds. Twenty-six back-in sites span back-in 30-amp, back-in 30-amp water-and-electric, back-in 50-amp, and back-in 50-amp water-and-electric categories, carrying water, sewer, and electric where noted, sized to 25 feet. Two things to plan around carefully: the 25-foot cap is genuinely restrictive and rules out most modern RVs, so this suits vans, small trailers, and truck campers rather than coaches, and the water-and-electric categories do not carry sewer at the site. Twenty-four tent sites make this substantially a tent property. A dump station, restrooms, showers, and firewood handle the practical side. Walking trails, a community fire pit, and the surrounding forest fill the grounds, with swimming, fishing, canoeing, kayaking, hiking, biking, and picnicking on and around the river. The dark central Vermont sky makes for excellent stargazing. Pets are welcome. Vermonters called the Winooski the Onion River for the wild leeks along its banks before European settlement, and the name stuck to the campground. Plainfield sits 10 to 15 minutes from Montpelier — the smallest state capital in the country and the only one without a McDonald's — with Goddard College, the Groton State Forest, and the Northeast Kingdom all close. Summer and foliage drive demand. Reserve ahead, and check your rig against the 25-foot limit.
