Carnegie State Vehicular Recreation Area is a 1,500-acre off-highway vehicle park located in the Diablo Range foothills. The terrain features a diverse range of trails, including steep hill climbs, winding canyons, and sandy washes suitable for motorcycles, ATVs, and 4x4 vehicles. The park is managed by the California Department of Parks and Recreation and is designated specifically for off-road recreation. Riders must navigate marked trails that vary by difficulty level to accommodate both beginners and advanced enthusiasts. The landscape is characterized by rolling hills and arid, Mediterranean-climate vegetation. No water or fuel stations are available inside the park boundaries, requiring visitors to be self-sufficient. Trail conditions fluctuate significantly based on recent rainfall and seasonal maintenance. The facility serves as a primary hub for northern California's off-roading community.
The ridges overlooking the canyon floor offer wide-angle views of the rugged, undulating terrain.
Check the park's official webpage for current trail closures due to fire danger or inclement weather before departing.
Ensure your vehicle meets the California Green Sticker or Red Sticker registration requirements.
Bring extra fuel and water, as there are no amenities for refueling or hydration within the park.
Do not ride off designated trails, as the park strictly enforces stay-on-trail policies to protect sensitive habitat.
The park may close periodically during or after heavy rainfall to prevent soil erosion and trail damage.
Helmets are mandatory for all riders; vehicles must be equipped with spark arrestors; noise limit regulations are strictly enforced.
