Campgrounds and RV parks near San Antonio Heights, CA

San Antonio Heights is an unincorporated community at the base of the San Gabriel Mountains in San Bernardino County, sitting just north of Upland and within sight of Mount San Antonio (Mount Baldy).

For full-service stays with paved pads and resort amenities, Bonelli Bluffs RV Resort and Campground sits in San Dimas with 504 paved full hookup sites, including 15 pull-through spaces, and many sites offering views of Puddingstone Lake. Fairplex RV Park in Pomona offers 183 full RV hook-ups with 50/30 amp service, plus cabins, a heated pool and spa, laundry, showers and a mini-market. For a more rustic setting, Camp Williams Resort in Azusa is tucked into the San Gabriel Mountains along the East Fork of the San Gabriel River with tent camping on the riverbank and full hookup RV sites shaded by oak trees, and Bonita Ranch Campground sits along Lytle Creek in the San Bernardino National Forest with sites near the water and trail access to Bonita Falls.
