Joshua Tree National Park covers 1,235 sq mi where the Mojave + Colorado Deserts meet, 2.5 hours east of LA. Nine campgrounds, all primitive — NO water at any of them, NO dump stations inside the park. Bring everything in, take everything out. Rent rate: free entry (with park pass), $20-25/site. Some sites are first-come-first-served (Belle, White Tank, Hidden Valley); reservations open 6 months out via Recreation.gov for the rest. Adjacent BLM land south of the park (Joshua Tree South + Chuckwalla Bench) offers free dispersed camping with similar landscape — the savviest RVers basecamp on BLM and day-trip into the park.
The notes below are PickRV's editorial record. Only the figures in the strip at the top of the page, each with its link and date, were re-read on the park's own pages.
Joshua Tree marks the seam between the higher, cooler Mojave Desert and the lower, hotter Colorado Desert in southeastern California. The Mojave side carries the namesake Joshua trees and rounded quartz monzonite boulders that draw climbers and night-sky watchers; the southern Colorado side trades them for ocotillo, cholla, and palm oases.
October through April brings comfortable daytime temperatures; spring wildflower blooms (most often late February through April) follow wet winters and are never guaranteed.
Most park campgrounds — including Jumbo Rocks, Belle, and White Tank — accept RVs but offer no hookups and limited dump-station access; Cottonwood Campground at the southern end allows RVs up to about 35 ft.
What the official site doesn't tell you
NPS.gov mentions primitive camping but doesn't drive home: with NO water + NO dump in 7 of 9 campgrounds, your 35-gallon fresh-water tank is your CEILING. A family of 4 burns through that in 2-3 days. Two practical hacks: (1) bring 5+ collapsible 5-gallon water jugs as backup; (2) the gas station at the Cottonwood (south) entrance has a non-potable spigot for $0.25/gal — fill jugs there, NOT the park drinking water. Second: BLM Joshua Tree South is the SECRET — free dispersed camping, same desert landscape, 10-min drive to the park's south entrance, 30-day max stay. Park your big rig there, drive a smaller vehicle into the park during the day. Third: the most-overlooked sunset spot is Keys View — stunning vista of the Coachella Valley + San Andreas Fault; watch the smog burn off as the sun drops. Fourth: cell signal is dead inside the park except at Black Rock + Cottonwood entrances — download offline maps before. Fifth: 'Joshua tree' is technically a Yucca brevifolia, not a tree — the name is from Mormon settlers comparing it to the biblical figure; the park's namesake is dying off in the southern half due to climate-shifted rainfall, so see it now while the iconic groves remain.
