Welcome to the Lower Ranch

Motorcycle and ATV Area

This 3,300-acre area, set aside for motorcycle and ATV use only, has about 128 miles of trails. Additional OHV opportunities include a vintage track, two practice motocross tracks, an ATV track, a TT track, an intermediate kids track, a beginner area, and a track for bikes and ATVs with an engine size of 90cc or less. Next to Walnut and Lodge Camps, there are two children’s areas set aside only for smaller motorcycles and ATVs with an engine size under 90cc.

There are four campgrounds located in the Lower Ranch. More information on Camping.

The San Andreas Fault divides the park into two different landscapes. Half of the Lower Ranch is on the Pacific Tectonic Plate, characterized by sandy granitic soil and steep terrain covered in chaparral plants like pine, sage, and sticky monkey flower. The other half of the Lower Ranch is on the North American Tectonic Plate, characterized by clay-rich adobe soil with rolling hills covered in grasslands and oak woodlands.

The areas located on the North American Plate are subject to seasonal closures due to the clay-rich adobe soil for public safety and natural resource protection. Check ahead of time on our website or follow us on social media for updates (Facebook & Instagram). The areas on the Pacific Plate are always open.
