Canyon walls stand over Watchman Campground, by the south entrance to Zion, and from the sites the Watchman goes orange while the shade climbs the rest of them. That's your first night on the Grand Circle. A couple of nights later the rig is under the pines at Bryce Canyon, and the week closes on the Grand Canyon's South Rim, the canyon filling with light from the top down at first sun. The route climbs I-15 into Utah, crosses to Bryce, then drops south into Arizona, three national parks that most families give a night or two apiece.
Book the Watchman site before you choose the rig. Every site at Watchman is reservable on a six-month window, and 92 of the 184 have electric hookups, which on a Zion afternoon is the difference between running the air and sitting out the heat. The dump station there runs year-round, so empty the tanks and top off the water before you leave, because Bryce and the South Rim have no hookups inside the parks.
Over the Zion tunnel to Bryce, then south to the South Rim
East of Watchman, the Zion-Mt. Carmel Highway switchbacks up the canyon wall and through a tunnel in the sandstone, then comes out into slickrock country on the way to Bryce. The Park Service posts large-vehicle rules for that highway on length, width and height, and they decide which class of motorhome belongs on this loop, so measure the listing against them before you book. If you'd rather spend the whole week in the canyon, look at RV rentals near Zion National Park.
From North Campground you walk out to Bryce's rim, and the ground drops away into an amphitheater of orange, pink and white hoodoos, brightest in the low light at either end of the day. North Campground has no hookups and runs its dump station in summer, so it's a dry night, and some loops close in winter.
Pines run right to the edge at the South Rim, and the week's last evening there is the one to plan around water. As of September 2026 the Park Service lists Trailer Village closed and Mather Campground with no hookups, which leaves no hookup site inside the park. Under the park's water restrictions, Mather's dump and water station stays open while the campground spigots are off and fires are banned. Roll in with the fresh tank full for a dry night at Mather, or take a hookup night outside the park in Tusayan or Williams and drive in for the rim.
From the rim the loop runs back to Las Vegas across the desert, or the week keeps going. Phoenix is the natural finish south of the Grand Canyon, and running the loop in reverse ends it in Salt Lake City, north of Bryce. Cruise America and El Monte RV both run one-way rentals from Las Vegas, and the listing shows which drop-off cities pair with it.
Las Vegas KOA at Sam's Town and the Strip lights
When the week is Las Vegas itself, the rig stays parked and the air stays on. Las Vegas KOA Journey at Sam's Town is out on the Boulder Highway, and after dark the casino towers and the glow of the Strip light the sky to the west while the kids are still in a pool that stays open all year. An RTC bus runs from the park to Allegiant Stadium, so nobody moves the rig on a game night.
In July the power is the point. The KOA lists full-hookup pull-throughs at 40 and 70 feet with 50-amp service, and 70 feet is its longest site, enough to run the air through the worst of the afternoon.
Red Rock Canyon's banded red sandstone rises at the west edge of the valley, an easy afternoon from the pad, and Valley of Fire, Mount Charleston and Death Valley are longer days out. For two people who want to sleep out at those parks instead of driving back, a Las Vegas campervan is the smaller rig, and those trips are written up there.
Lake Mead RV Village at Boulder Beach
At Boulder Beach the bare desert hills run down to the water, and from a lake-view site the shoreline goes gold and then rose as the sun sets over Lake Mead. It's a Las Vegas weekend habit, close enough to leave town on a Friday after work, and a gentle first night for a longer rental before the drive north to Zion.
Lake Mead RV Village has 115 RV sites, many of them pull-through, all with power, water and sewer. That's the reason to bring a rig here, since the Park Service campgrounds on the lake have no hookups.
