RV Camping near Thermopolis, Wyoming

Shell Campground

7 RV Sites

Shell Campground in Shell, Wyoming, offers seven full-hookup RV sites with 30 and 50-amp service and rigs accepted to 50 feet, at the base of the Big Horn Mountains on Highway 14. Open all year with cabins, a general store, and a community fire pit, it is the closest full-hookup campground to the range's dramatic western escarpment. Seven sites carry water, sewer, and electric on 30 and 50-amp in back-in and pull-through configurations, sized to 50 feet. Cabins round out the accommodations. A general store, propane fills, laundry, restrooms, showers, firewood, and WiFi handle the practical side, and the campground stays open year-round — genuinely useful on a mountain route that sees traffic in every season. With seven sites, reserve rather than counting on availability. Pets are welcome. A community fire pit anchors the evenings, with picnicking on the grounds and mountains rising immediately west. The Old Shell Store is a block and a half away, serving what the locals will tell you are the best burgers around. The position is the point. Highway 14 is the principal western approach to Bighorn National Forest and the main route connecting the Big Horn Basin to Yellowstone and Grand Teton. Shell Falls is 15 minutes up the highway, the Big Horn National Forest five minutes, and the Antelope Butte Recreation Area 20 — with skiing there in winter and a national park within reach. Summer drives the heaviest traffic on the mountain route. With seven sites at the base of Shell Canyon, reserve well ahead.

Powder River Campground

3 RV Sites, 8 Tent Sites

Powder River Campground in Kaycee, Wyoming, offers full-hookup RV sites with 20, 30, and 50-amp service and tent camping just off Interstate 25, with rigs accepted to 50 feet on a big-rig-friendly layout. Fire pits, picnic tables, laundry, and site WiFi serve travelers in the heart of Johnson County's Powder River Basin. Back-in sites carry water, sewer, and electric on 20, 30, and 50-amp, sized to 50 feet, with fire pits and picnic tables. Tent sites cover simpler camping. A dump station, laundry, restrooms, showers, firewood, a boutique shop, and WiFi handle the practical side. Passport America and military discounts are honored. One vehicle is allowed per site, with an extra vehicle fee of $5 per night on arrival, and refunds do not include service and credit card processing fees. On-site facilities are practical rather than programmed. Hiking and boating run from the area, and off-roading is nearby — this is a base for the surrounding country rather than a destination in itself. Pets are welcome. Kaycee sits in the Powder River Basin, cowboy country in the most literal sense, where nineteenth-century open range cattle culture played out in the same red-bluff canyon and sagebrush landscape that surrounds the campground today. The Big Horn Mountain foothills are close, and Johnson County remains one of Wyoming's least-visited but most historically layered communities — the Johnson County War played out here, and the tourism development that reshaped other I-25 and US-87 towns largely passed it by. Summer interstate traffic is the peak. Reserve ahead for July and August.

Alpine Valley RV Resort

119 RV Sites

Alpine Valley RV Resort in Alpine, WY, offers 119 full-hookup RV sites with 20, 30, and 50-amp service and room for rigs up to 75 feet. Site categories run from standard back-ins and pull-throughs through deluxe back-ins, deluxe gravel back-ins, deluxe pull-throughs, and premium back-ins, with dedicated ADA sites. All carry water, sewer, and electric with site-delivered WiFi, a fire pit, and a picnic table. At 75 feet the pull-throughs take long coaches. Laundry, a bathhouse with showers, and a playground cover the essentials. Pets are welcome, with a dog park. Walking trails and river frontage run the property, with whitewater rafting, boating, and picnicking, and off-road riding nearby. Alpine sits a quarter mile from Palisades Reservoir, adjacent to the Snake River, within a scenic drive of Grand Teton National Park and close enough to Yellowstone to serve as a genuine two-park base. Coming from Afton, turn right onto 89 toward Jackson and the resort is the first right. Rates by site category are on the booking page. Summer in the Tetons books out months ahead — reserve early.

HAPI Trails Ranch

10 RV Sites

HAPI Trails Ranch in Driggs, Idaho, is a horse-specific facility in the Teton Valley offering 10 RV sites with water and electric on 30 and 50-amp service and rigs accepted to 80 feet, alongside dry camping areas, stalls, corrals, and arenas. One requirement is absolute: do not book unless you are traveling with a horse. Ten back-in sites carry water and electric on 30 and 50-amp, sized to 80 feet — note there are no sewer hookups, so plan tank capacity. Multiple dry camping areas supplement the hookup sites. Horse paddocks and pens share the grounds with a professional network of stalls, corrals, and arenas purpose-built to make horse-and-rider camping straightforward. Office hours are by appointment only, so arrange your arrival in advance. Pets are welcome. The ranch is home to the Horse Adoption Program, Inc., a nonprofit dedicated to rehabilitating and re-homing at-risk horses, and access is reserved exclusively for guests arriving with their own horses. That restriction is the whole model, and it produces facilities considerably better suited to equestrian travel than a general campground with a few pens. Driggs sits in the wide, glacier-carved Teton Valley of eastern Idaho, where the spired peaks of the Tetons rise from the eastern skyline and working hay meadows stretch beneath enormous skies. Riding country opens up in every direction. The Teton Valley season runs summer through early fall, when the high country is open and the riding is at its best. With 10 sites and an appointment-only office, arrange your stay well in advance.

Old West RV Park

13 RV Sites

Old West RV Park in Reed Point, Montana, offers 13 full-hookup RV sites off Interstate 90 at mile marker 392, with 20, 30, and 50-amp service and rigs accepted to 75 feet on a big-rig-friendly layout. Back-in and pull-through sites carry water, sewer, and electric with picnic tables, on the Yellowstone River between Billings and Livingston. Thirteen sites carry full hookups on 20, 30, and 50-amp in both back-in and pull-through configurations, sized to 75 feet, with picnic tables. The big-rig-friendly layout means long coaches can get in and out without a difficult approach after a day on the interstate. Laundry, restrooms, and showers handle the practical side, and WiFi reaches the sites. Pets are welcome. The park is a stopover rather than a resort, and it is honest about that. What it offers is a clean full-hookup site with straightforward highway access in a genuinely rural Montana setting — a small agricultural community on the Yellowstone River rather than a strip of interstate frontage. On-site facilities stay deliberately simple: laundry, restrooms, hot showers, and site WiFi are what an overnight guest actually uses, and the pull-through sites mean you can stop for a night without unhitching. Hiking, biking, and birding run from the area. Reed Point sits in Stillwater County, 60 miles west of Billings and 50 miles east of Livingston, which makes it a natural midpoint on Montana's most traveled interstate corridor. The Yellowstone River carries excellent fishing, and the Absaroka Range forms the southern skyline. Yellowstone National Park is within reach via Livingston and Paradise Valley. The park serves the Montana travel season, with summer bringing the heaviest I-90 traffic and Yellowstone-bound visitors. With 13 sites, arriving late in the day during July and August is a gamble — reserve ahead.

Jolley Camper RV and Cottages

14 RV Sites, 10 Tent Sites, 3 Cottages

Jolley Camper RV and Cottages in Ashton, ID, offers 14 RV sites, 3 cottages, and 10 tent sites, with 30-amp service and room for rigs up to 50 feet. The park publishes two site categories — full-hookup sites carrying water, sewer, and electric with site-delivered WiFi, and water-only sites — so confirm which you're booking and which layout it uses when you reserve. Note the electrical: service is 30-amp, so a rig wired for heavier draw will need an adapter and some load management. Laundry, a bathhouse with showers, a dump station, sport courts, and a community fire pit cover the rest. Two vehicles are allowed per site, with a nightly fee charged on arrival for each additional one. Pets are welcome. Volleyball is the on-site recreation, and the location does the rest. Ashton sits in the upper Snake River Plain near the Wyoming border, at the western gateway to Yellowstone's Bechler and Cave Falls areas, with the Mesa Falls Scenic Byway and the St. Anthony dunes close by. Rates for sites, cottages, and tent spots are on the booking page. Yellowstone season books out early.

Riverside RV Park - Kemmerer

38 RV Sites

Riverside RV Park in Kemmerer, Wyoming, offers 38 full-hookup RV sites on Ham's Fork River, with 20, 30, and 50-amp service, cable TV, and rigs accepted up to 120 feet — among the most generous length allowances of any park in southwestern Wyoming. The park has been taking travelers for more than 50 years. Thirty-eight sites carry water, sewer, and electric on 20, 30, and 50-amp in both back-in and pull-through configurations, with picnic tables at the sites. The 120-foot maximum accommodates essentially any rig on the road, including toads and trailers behind a long coach. Cable TV and WiFi are available at the sites. Pets are welcome. The river is the setting and the recreation. Ham's Fork runs along the property, giving guests trout fishing directly from camp in a high-desert river valley. On-site facilities are otherwise deliberately simple — this is a riverside park rather than a resort, priced and equipped as such, and its 50-year run reflects consistency rather than amenity investment. Kemmerer sits on US-189 in Lincoln County. Fossil Butte National Monument, preserving the most complete Eocene freshwater fish fossils in the world, is the region's signature attraction, and the town is where J.C. Penney opened his first store in 1902 — the original building still stands. The Star Valley outdoor corridor runs north between the Wyoming and Salt River ranges. The park serves the southwestern Wyoming season, with summer fossil-country tourism and river fishing driving demand. Reserve ahead for summer weekends, when Kemmerer's limited lodging inventory tightens.

Sugar City RV Park

27 RV Sites

Sugar City RV Park in Sugar City, ID, offers 27 RV sites with 20, 30, and 50-amp service and room for rigs up to 65 feet. Sites come in two categories that spell out exactly what's included: deluxe full-hookup 50/30-amp sites with water, sewer, and access to bathrooms, showers, and laundry, and standard electrical-only sites at 50/30/20-amp. Full-hookup sites carry water, sewer, and electric, in large pull-through and back-in layouts, with ADA-accessible sites available. The park is rated big rig friendly and at 65 feet the pull-throughs take a long coach. A pavilion, sport courts, and a dog park round it out. Pets are welcome. Picnicking is the on-site recreation. The park's own pitch is honest about it: park the RV, plug it in, and go see eastern Idaho. Sugar City sits in Madison County on the Snake River Plain minutes from Rexburg, at the gateway to Yellowstone, the Tetons, and some of the most spectacular country reachable by road in the continental United States. Rates for full-hookup and electric-only sites are on the booking page. Summer, with Yellowstone an easy drive, is the busy season.

from $35/night

Lakeview Haven

28 RV Sites

Lakeview Haven in Glendo, WY, offers 28 full-hookup back-in RV sites with 30 and 50-amp service and room for rigs up to 50 feet. Every site is a back-in carrying water, sewer, and electric. Laundry, a bathhouse with showers, propane fills, and on-site dining handle the essentials, with WiFi across the property and cabins available for guests without a rig. Campfires are allowed in the public fire pits rather than at individual sites, and tents need their own tent site — you can't pitch one beside a cabin. Pets are welcome, and there's a playground and a basketball court for kids. A fishing pier on the property puts guests on the water, and the community fire pit is where the evening ends up. Glendo sits in the high plains of Platte County on the shore of Glendo Reservoir, a North Platte River impoundment known for walleye and for some of the emptiest, clearest night skies in Wyoming. Rates for sites and cabins are on the booking page. The reservoir's summer season is short and busy — reserve ahead for July and August.

Yellowstone Lakeside RV Park and Campground

34 RV Sites

Yellowstone Lakeside RV Park and Campground in Rigby, ID, offers 34 full-hookup RV sites with 30 and 50-amp service and room for rigs up to 80 feet. Sites come in two categories, back-in 30/50-amp and pull-thru 30/50-amp, each carrying water, sewer, and electric with a fire pit and picnic table. The park is rated big rig friendly, and at 80 feet the pull-thrus take the longest coaches. Laundry, firewood, propane fills, a dump station, a pavilion, and a pet washing station cover the practical side. Pets are welcome, with a dog park. An outdoor pool fills the grounds, with an amusement park nearby. Rigby sits in the upper Snake River Plain east of Idaho Falls. The park is family-owned and open year-round, and it functions as the most practical and reasonably priced overnight base for travelers heading to or from Yellowstone. Rates and availability are on the booking page. Park season books out early — reserve well ahead for summer.

Tower Valley RV Park

14 RV Sites

Tower Valley RV Park in Hulett, Wyoming, offers 14 full-hookup RV sites with 30 and 50-amp service and rigs accepted to 50 feet, in the Wyoming Black Hills near Devils Tower. Every site is back-in with generous room to maneuver, and kayak rentals are available on the creek. Fourteen back-in sites carry water, sewer, and electric on 30 and 50-amp connections, sized to 50 feet, with fire pits and picnic tables. Every site is back-in, but there is plenty of room for maneuvering — worth knowing rather than assuming tight quarters. One practical detail the park calls out: not all hookups are on the driver's side, and those sites are identified as passenger-side, so check when booking if it matters for your setup. Pets are welcome. A creek runs the property with kayak rentals available, and canoeing and kayaking are the main on-site recreation. The amenity set is deliberately simple — this is a comfortable base rather than a resort. Hulett sits in Crook County on WY-24 near the Belle Fourche River valley, and the park's real distinction is proximity: it is the closest full-service RV park to Devils Tower National Monument. The nation's first national monument rises 1,267 feet as a volcanic neck visible across the surrounding country, with Belle Fourche River fishing and the Black Hills ponderosa pine forest filling out the area. Summer Devils Tower traffic is the peak, and the August Sturgis rally tightens the whole region. With 14 sites this close to the monument, reserve well ahead.
