RV travel guide
Riverside County
County seat Riverside, 7,206 sq mi across California. Everything an RV traveler should read before rolling in — where you can boondock, the roads worth the detour, and the local rule that actually matters.
The county in brief
A traveler's read on Riverside County
Joshua Tree National Park's western entrance opens directly into Riverside County, and the snowbird wintering economy at Indio's Coachella Valley resorts pushes the county's seasonal RV population past 200,000 between November and March per the local CVB.
CA-74 Palms to Pines Scenic Byway climbs from sea-level desert at Palm Desert to 6,000-ft pine forest at Mountain Center in 34 miles — a 25:1 grade ratio that earns it the most-warned descent on any California state route, with Caltrans posting mandatory brake-check stops for vehicles over 10,000 GVWR. The Salton Sea's northern shoreline sits inside the county and is the lowest-elevation campable shore in North America at -227 ft below sea level.
