Utah's big motorhome week is a circuit of red-rock national parks with the rig parked inside most of them, Zion first, then Bryce, then Capitol Reef, and Arches at the far end. Families usually give it a week or more, pulling into a park campground by late afternoon with everyone aboard and waking up to sandstone outside the windshield. Scenic Byway 12, the road over the top of the loop between Bryce and Capitol Reef, is the stretch people plan the whole route around.
Those park campgrounds are the first thing to book, and their sites decide how long a motorhome the family can bring. Watchman and Devils Garden both open reservations six months ahead as of September 2026, and the dates you get at Zion and Arches set the rest of the loop. The towns outside the park gates fill the gaps as hookup bases, the places to plug in, top up the water and empty the tanks before the next dry night.
Zion and Bryce on the west side of the loop
Watchman is the Zion night, a campground of cottonwoods by the Virgin River with the canyon's west wall going gold above the loops at sundown. Watchman's campground page caps RVs at 40 feet and lists electric hookups only, with a dump station on site. Its shaded sites clear 12 feet 6 inches, so check the roof height on a listing before picking one of those.
The Zion-Mount Carmel tunnel on the road east has its own size rules for big vehicles, and those, along with the full-hookup parks in Springdale, are on the Zion RV page. Families coming up from the south can start the loop from St. George, a winter RV-resort town with its own RV page.
Up at Bryce the trails switchback off the rim into amphitheaters packed with orange hoodoos, and the evening light on them is reason enough to stay the night. Bryce's campground page keeps North Campground open all year and closes Sunset for winter, with the dump station running spring to fall. Fill the fresh tank and empty the others here, because the next two park nights run dry.
Capitol Reef and Arches on the east side of the loop
Fruita waits at the east end of Byway 12, a campground set among orchards on the canyon floor with red cliffs standing over it. Its loops have no hookups and no pull-throughs, and length sorts the sites, with Loops A and B running mostly under 40 feet and Loop C taking rigs from 40 to 52. Between Capitol Reef and Arches, Goblin Valley's basin of mushroom-shaped rock is worth an afternoon of scrambling among the goblins.
Devils Garden is the last park night, its sites tucked among sandstone fins that turn orange at dusk. Sites run 20 to 40 feet, with no electric hookups and no dump station, and from November through February they go first-come once the reservation season ends. Moab, just outside the gate, is the loop's other hookup base, and its full-hookup parks and Arches days are on the Moab RV page.
For two people, or anyone who'd rather not plan around Fruita's loops and the Bryce viewpoint lots, a smaller rig makes the park nights simpler, and the Utah campervan page runs Bryce, Capitol Reef and Goblin Valley as nights of their own.
Salt Lake City to Las Vegas or Denver, one way
The loop can also run as a line. From Salt Lake City the road heads south through the Great Basin, past salt flats and into red-rock desert, and the parks fill the middle of the week with no drive back north at the end. The Las Vegas run leaves Zion and drops into the Mojave, and the Denver run leaves Arches eastbound over the Rockies.
The park campgrounds are still the first booking, and a one-way itinerary leaves less room to shift their dates. The Salt Lake City end of the route, first nights included, is on the Salt Lake City RV page. Cruise America runs one-way rentals between its locations, with hubs in Las Vegas and Denver at the far ends of this route.
Summer weeks at Bear Lake and Lake Powell
Up on the Idaho line the water of Bear Lake turns a bright turquoise, and Rendezvous Beach stretches long and open beside it with almost no shade. Rigs park for the week here, everyone splitting the days between the sand and the campsite while the air conditioning carries the afternoons.
The beach has two full-hookup loops, Birch with 60 sites from 64 to 105 feet and Big Creek with 46 from 44 to 68, in pull-through and back-in, and the season runs from about early May to the third weekend of October. It's the summer lake week for rigs out of northern Utah, and the Salt Lake City RV page covers the drive up.
At the other end of the state, on the Arizona line, Lake Powell fills red sandstone canyons, and houseboats tie up in the coves below Wahweap. Summer out here is hot, which makes it the same kind of week, with the rig plugged in and the days spent on or beside the water. Wahweap's campground has 139 full-hookup sites on 30 and 50 amp, with sites up to 45 feet.
