Ada/Ranch Campground sits within Hollister Hills SVRA at 660 feet elevation, offering two sites that accommodate both tents and RVs. The campground costs $10 per night and provides warm showers, flush and vault toilets, and free Wi-Fi in the Lower Ranch area. It's a quiet, family-friendly basecamp for exploring the park's OHV trails and the nearby Troll Trail.
Ada / Ranch Campground offers multiple camping options, including tent camping and ADA-accessible campsites.
The Ohlone people lived on this land for thousands of years before Spanish colonists incorporated the area into Rancho San Justo and Rancho Cienega del Gabilan land grants. Weather and SeasonsFall brings the ideal conditions, with daytime highs in the 60s to 70s and cool nights. Trails on the sandy granitic side stay rideable while wildlife activity remains strong. Summer heats up into the low to mid-90s, best for early morning rides. Winter mornings drop into the low 30s but warm to the upper 50s by afternoon. Rain transforms the adobe clay soil into sticky, unrideable mud. Weekdays see fewer visitors than holiday weekends, when the campground often fills to capacity during Thanksgiving and Easter.
ElevationJourney through a dramatic vertical landscape that climbs from 660 feet to an impressive 2,425 feet within the park boundaries. This nearly 1,800-foot elevation change creates a dynamic playground of ridgelines, valleys, and sweeping vistas that reward adventurers with ever-changing perspectives and terrain challenges at every turn.
Natural Features and SceneryThe San Andreas Fault divides the landscape here into two distinct riding environments: challenging clay-rich adobe soil on one side and sandy granitic terrain on the other. Oak woodlands cover the rolling hills, and seasonal creeks appear after winter rains. The geological split creates varied ecosystems that shift from dense woodland groves to open grasslands. At 660 feet elevation, the terrain stays relatively moderate, though the clay side becomes impassable when wet.
Geological RegionDiscover the fascinating geological story written in the rocks of the Gabilan Mountains, where the mighty San Andreas Fault divides the landscape into two distinct worlds. On one side, challenging clay-rich adobe soil tests your skills when wet; on the other, sandy granitic terrain provides year-round riding opportunities. This geological diversity creates an ever-changing outdoor playground that keeps even seasoned adventurers coming back for more.
