Kids scramble granite piles the size of houses in Joshua Tree National Park while the Joshua trees throw long, crooked shadows across the sand. By evening the family is back down in the Coachella Valley under palms and a wall of mountains. The pool is lit, a pickleball game is going, and the day's dust comes off before dinner.
From fall into spring the desert is dry and mild, and the valley fills with snowbirds parked for the season and families down for a school-break week. Summer is the park's off-season, with some campgrounds closed and afternoons hot enough that nobody wants to leave the pool.
A motorhome suits this trip because it doesn't have to move. It stays hooked up at the resort all week, and every drive into the park is a day trip with lunches packed and nothing to stow.
Joshua Tree from a Palm Desert base
Hidden Valley and White Tank are the rock piles most families remember, and they are also where the park is strictest about rig size. The Park Service limits RVs and trailers to 25 feet combined at those two campgrounds and to 35 feet at the rest unless a campground says otherwise. None of the park's campgrounds has hookups, so a family in a full-size motorhome sleeps down in the valley.
Emerald Desert RV Resort in Palm Desert has full hookups with water, sewer, and 30 and 50 amp service, though its pull-throughs are limited and not meant for extended stays, as of September 2026. It is one of the private parks the Park Service lists outside the park. If you leave Orange late on the first day, Orangeland RV Park in the city has full-hookup sites for a night before the desert drive.
A shorter rig can still spend one dry night inside the park at a campground that fits its length. Arrive with empty tanks, keep the generator to the posted hours, and dump on the way out at Black Rock or Cottonwood, the two campgrounds the park lists with a dump station. A couple set on sleeping among the Hidden Valley boulders will have an easier time in a campervan from the California listings.
The Ortega Highway to Lake Elsinore
When a desert week is too much, the Ortega Highway (CA-74) turns south Orange County into a mountain weekend. The road climbs through oak canyons and chaparral switchbacks into the Cleveland National Forest, then curves high above Lake Elsinore on the far side. Families run it for a night or two while school is still in session.
Two Forest Service campgrounds sit right on the highway, Upper San Juan and El Cariso, with the chaparral close around them. Upper San Juan has 18 sites and posts no length limit on its page. El Cariso has 24 sites and stays open year round, but it holds vehicles to 22 feet, which is shorter than most family motorhomes, so reserve the site before you settle on a rig.
For a night on full hookups, Ortega Oaks RV Park has them inside the national forest on the highway itself. Plan to drive in daylight, since the Forest Service notes periodic nightly closures on SR-74 for Caltrans widening as of September 2026.
The other overnights close to Orange belong to other trips. The Disneyland week, with the rig parked at a hookup park near the gates, is planned from Anaheim, and Crystal Cove on the coast is covered from Costa Mesa. O'Neill Regional Park is the close-in county campground for a quick night without leaving Orange County.
