Evening on Yellowstone's Grand Loop comes down over the water at Fishing Bridge, where rows of rigs park in the lodgepole at the north end of Yellowstone Lake. The next morning is the park at road speed, a bison working the shoulder, steam lifting off the Firehole, sulfur coming in through any open window. Over a week the figure eight moves you to a new stretch of the park most nights, and in a motorhome the order of those nights is most of the planning.
Fishing Bridge and the capped campgrounds around the loop
Two or three nights at Fishing Bridge RV Park hold the week together. It's the only campground in Yellowstone with water, sewer and 50-amp hookups, and it takes rigs up to 95 feet, per the Park Service campgrounds page. With the furnace on and the tanks hooked up, it's a base for day drives around the lake and a reset between the dry nights that fill the rest of the trip.
Those dry nights go to campgrounds with length limits, and the tightest one you book decides the rig. The park's length table puts Madison and Bridge Bay at 60 feet, Grant Village at 50 and Canyon at 40, each with a dump station and no hookups. Canyon usually sets the class, because its pads sit in the lodgepole a short drive from the rim of the Grand Canyon of the Yellowstone and hold the shortest rig of the four.
A loop that works opens with those nights at Fishing Bridge, heads north to Canyon, crosses west to Madison for the geyser side, and swings south to finish on the lake at Grant Village or Bridge Bay. Old Faithful and the Firehole basins are day stops out of Madison, steam drifting over the boardwalks and the sulfur still in the rig on the drive back to the pad. Empty the tanks at each campground's dump station on the way out, so the rig rolls into the next dry night with room to spare.
Grand Teton from Colter Bay and Gros Ventre
South of Yellowstone the Teton range rises straight up from the far shore of Jackson Lake, and Colter Bay puts a rig under lodgepole on the near side for the last nights of the trip. It's the usual add-on to a Yellowstone week, a short leg south from the lake. Colter Bay RV Park has full hookups at 20, 30 and 50 amps, with pull-through sites for rigs up to 45 feet overall and back-ins to 30 feet. It runs early May to early October as of September 2026.
Farther south toward Jackson, Gros Ventre Campground adds electric sites and a dump station for the Jackson end of the park, open late April into October. The Teton trailheads and Jackson itself get their own write-up on the Jackson campervan page.
A hookup base at Gardiner or West Yellowstone
At the north entrance, canyon walls climb over the Jardine road above Gardiner, and the town works as a base when Fishing Bridge is booked out. Sun Outdoors Yellowstone North is a quarter mile from the park, with pull-through sites and full hookups, open from the start of May to the start of October as of September 2026. From there the early drive east runs out to Lamar Valley and the bison scattered across its flats.
Slough Creek, the campground out in Lamar country, takes rigs only to 30 feet on the Park Service table. A couple who want to sleep out there will fit it better in a smaller rig, and the Yellowstone campervan page covers Lamar, the canyon rim and the geyser basins as days of their own.
West Yellowstone does the same job at the west entrance, closest to Madison and the geyser side, with RV parks such as Yellowstone Grizzly RV Park in town. For rig trips elsewhere in the state, start with the Wyoming RV page.
