Campgrounds and RV parks near Diablo Grande, CA

Diablo Grande sits in the rolling foothills of the Diablo Range in western Stanislaus County, southwest of Patterson and roughly a 90-minute drive from both the Bay Area and the northern San Joaquin Valley. The location puts RV travelers within easy reach of two distinct camping environments: shaded riparian state parks along the Stanislaus and Merced rivers to the east, and rugged oak-grassland parks in the Diablo foothills to the west. Kit Fox RV Park LLP is the closest full-service option, with hookup sites geared to travelers passing through the Interstate 5 corridor. East of Diablo Grande, Caswell Memorial State Park preserves a stand of valley oak riparian forest along the Stanislaus River near Ripon, and George J Hatfield State Recreation Area offers river-frontage camping on the Merced River south of Modesto. West and south, Henry W Coe State Park protects more than 87,000 acres of wild backcountry in the Diablo Range, while Carnegie State Vehicular Recreation Area provides dedicated OHV camping in Corral Hollow between Tracy and Livermore.

California State Parks sites are reserved through ReserveCalifornia. Reservations at Caswell Memorial are available through ReserveCalifornia up to six months in advance, and the same six-month rolling window applies at Henry W Coe State Park, where the Coe Ranch Campground tends to fully book on Saturday and many Fridays during spring, summer, and holiday weekends. The group campground at George J Hatfield accepts reservations through ReserveCalifornia up to six months in advance, while the family tent sites there are first come, first served. Carnegie SVRA has a designated campground with 23 sites available on a first-come, first-served basis, so arriving early on Friday is the best strategy on peak riding weekends. Private parks such as Kit Fox RV Park LLP take reservations directly through the operator.
