39 RV Sites, 4 Cabins, 18 Tent Sites, 5 Hotel Rooms
Yellowstone Hot Springs Resort in Gardiner, Montana, offers 39 RV sites, nine cabin and hotel-room units, and 18 tent sites eight miles north of Yellowstone's North Entrance, with 20, 30, and 50-amp service and rigs accepted to 40 feet behind a gated entrance. Three mineral spring pools of graduated temperature are the reason to book. Thirty-nine sites run in full-hookup and electric-only categories carrying 20, 30, and 50-amp, sized to 40 feet, with fire pits, picnic tables, and site WiFi. The electric-only option suits self-contained rigs at a lower rate. Nine cabins and hotel rooms and 18 tent sites round out the accommodations. A laundry, dump station, restrooms, showers, and firewood handle the practical side, with a gated entrance controlling access. The hot springs define the property. Three mineral pools of graduated temperature — a cold plunge, a 100-degree pool, and a 106-degree pool — are fed continuously by water drawn straight from the earth, chemical-free. An outdoor pool, fitness center, clubhouse, and pavilion round out the amenities, with hiking, biking, birding, and picnicking from the area and skiing and a golf course nearby. Pets are welcome. Gardiner sits at the south end of Paradise Valley where the Yellowstone River emerges from the mountains with the Absaroka Range rising on both flanks — one of the most strategically positioned properties in the greater Yellowstone ecosystem, eight miles from the park's only year-round entrance. Summer is decisively the season, with the springs drawing guests year-round. Reserve well ahead for June through September.

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.

46 RV Sites, 7 Tent Sites, 5 Lodges
The Longhorn Ranch Lodge & RV Resort in Dubois, WY, offers 46 full-hookup RV sites, 5 lodge rooms, and 7 tent sites, with 30 and 50-amp service and room for rigs up to 100 feet. Sites cover back-ins, pull-throughs, pull-in/back-out spots, dedicated big rig sites, river-front sites, and dry RV sites for guests who don't need hookups. Full-hookup sites carry water, sewer, and electric with cable TV, site-delivered WiFi, a fire pit, picnic table, and barbecue. At 100 feet of maximum length, this is one of the few parks in the region that can take the largest coaches without negotiation. Laundry, a bathhouse with showers, and a general store handle the essentials, and horse pens are available for guests traveling with stock. Pets are welcome, with a dog park. A hot tub and sauna, bike rentals, creek frontage, and picnicking fill out the on-site recreation, and the river-front sites are the ones worth asking for. Dubois sits at the eastern approach to Togwotee Pass on US 26/287, between the Absaroka Range and the painted badlands, on the road toward Grand Teton National Park. Rates for RV sites, lodge rooms, and tent spots are on the booking page. Summer is short and busy here — reserve river-front and big rig sites early.

12 RV Sites, 8 Cabins
Bearlodge Mountain Resort in Sundance, Wyoming, offers 12 RV sites and eight cabins at the foot of the Bear Lodge Mountains, with 20, 30, and 50-amp service on every site. Year-round camping is genuinely possible here — the hydrants are built to work down to twenty below zero, which is rare in northeast Wyoming. Twelve back-in sites carry 20, 30, and 50-amp service across the board, with the west eight sites also carrying water. There are no sewer hookups at the sites, though a dump station is available. Eight cabins provide enclosed lodging. On-site dining covers meals, and site WiFi reaches the property. The freeze-resistant hydrants are the detail that sets this apart — most campgrounds at this latitude shut water off for the winter, and this one does not. The resort serves several distinct purposes: a quiet mountain retreat, a hunting base camp, and an outdoor adventure staging point. The facilities are scaled accordingly — practical rather than programmed, with the surrounding landscape doing the work. Pets are welcome. Sundance sits in Crook County on I-90 at the foot of the Bear Lodge Mountains, in the Wyoming Black Hills. Devils Tower National Monument's volcanic neck is close, and the surrounding ponderosa pine forest and Warren Peaks give the area its outdoor recreation range. The town supplied the Sundance Kid his alias — from the 1887 Crook County jail and courthouse that still stands at Main and 3rd. Year-round operation makes this viable well outside the summer window, with hunting season and winter travel both drawing steadily. Summer Devils Tower traffic is the peak — reserve ahead for July and August.

30 RV Sites, 5 Cabins, 4 Tent Sites, 3 Hotel Rooms
Sleeping Buffalo Hot Springs & Resort in Saco, Montana, offers 30 RV sites, eight cabin and hotel-room accommodations, and four tent sites at a natural geothermal spring in the Milk River valley, with 20, 30, and 50-amp service and rigs accepted to 90 feet. An outdoor pool fed by the hot springs is the reason to come. Thirty sites run from back-in to pull-thru and prime pull-thru configurations carrying full hookups with 20, 30, and 50-amp, sized to 90 feet, with fire pits and picnic tables. Eight cabins and hotel rooms serve guests without a rig, and four tent sites cover simpler camping. Restrooms and showers are on site. The hot springs are the property's entire identity. Mineral-rich water, discovered by oil drillers in the early twentieth century, feeds an outdoor pool that serves both travelers crossing Montana's northern tier and the isolated agricultural communities of the Hi-Line. Swimming and horseshoes make up the rest of the on-site recreation — this is a remote resort in a landscape defined by the horizontal vastness of the northern Great Plains, and the amenity set reflects that honestly. Pets are welcome. The resort takes its name from a buffalo-shaped sandstone formation that the springs' development displaced. The water rises from a deep artesian formation beneath the Phillips County prairie, a genuine geothermal anomaly this far out on the plains. Saco sits on US-2 in Phillips County, hours from the nearest urban center. The resort serves both regional day-trippers from surrounding Hi-Line communities and travelers making the long cross-Montana traverse. Summer brings the heaviest road traffic, though the springs draw steady local use year-round.
