Joshua Tree National Park · caps RVs at 35 ft
Joshua Tree's campsites are wedged between 100-million-year-old monzonite domes — Black Rock and Cottonwood are the only loops without per-site rig surprises. Bring water, dump in Twentynine Palms.

Year-round (peak: October – April)
Granite monzonite domes set the rig-length physics of every Joshua Tree campground. Jumbo Rocks, Hidden Valley, and White Tank squeeze sites between car-sized boulders that have been there 100 million years — the result is per-site caps that vary site-by-site rather than loop-wide. Black Rock and Cottonwood (the two non-rock-bound loops) are the consistent 35-ft options. None of the park's campgrounds have hookups OR a dump station — closest dump is in the gateway town of Twentynine Palms. The desert's peak RV season inverts the rest of California: October through April is high demand, June through August clears out as ambient temperatures break 105°F. Park Boulevard and Pinto Basin Road handle any rig length but the loop pull-ins shrink quickly.

Other national parks in California
Yosemite
Every Yosemite Valley campsite operates under bear protocol — secure food inside the rig or the metal locker every night or get cited. Upper Pines holds 40-ft rigs but you'll dry-camp.
Sequoia
Generals Highway prohibits rigs over 24 ft between Hospital Rock and Giant Forest. Potwisha (year-round) and Lodgepole (May–Oct) are the 22-ft basecamps; Mineral King is a 22-ft hard cap on gravel.
Lassen Volcanic
Lassen's hydrothermal features collapse without warning — stay on the trails, and book Manzanita Lake (35 ft) at the north entrance because the south road sits above 8,500 ft and closes early.
Kings Canyon
Highway 180 drops 4,700 ft in 31 miles to Cedar Grove and closes November–April. Grant Grove campgrounds stay year-round at 30 ft; in-canyon loops are May–October only.
