Campgrounds and RV parks near Rancho Cucamonga, CA

Rancho Cucamonga sits at the base of the San Gabriel Mountains in California's Inland Empire, with campground options clustered in three directions: north into the San Bernardino National Forest foothills, west toward San Dimas and Pomona, and south into the Chino Hills. Bonita Ranch Campground sits in the San Bernardino National Forest along Lytle Creek, a short drive up the mountain from the main road. About fifteen miles west, Bonelli Bluffs RV Resort and Campground spans 2,000 acres within Frank G. Bonelli Regional Park, located 45 minutes east of Los Angeles at the base of the San Gabriel Mountains. Fairplex RV Park is situated next to Fairplex, which hosts hundreds of annual consumer, trade and exposition shows as well as the LA County Fair. Mountain Lakes Resort is also located in the Lytle Creek area. South of the city, Chino Hills State Park includes 14,102 acres of open space and 90 miles of hiking and equestrian trails. The mix lets campers choose between full-hookup resort sites near Los Angeles attractions and quieter creek or state-park sites in the surrounding hills.
