Hollister Hills SVRA is a 6,800-acre SVRA park and was the first SVRA made by the California parks department. The park is divided into three parts, the Upper Ranch, Lower Ranch, and Hudner Ranch. The Lower Ranch is for dirtbikes. While the Upper Ranch and Hudner Ranch are for 4x4s, visitors should stop first at the ranger station in the Lower Ranch to pay the $5 entry fee and get a map of the trails, as well as the lock combination to the gate at Hudner Ranch.
Adventure Trail is a short but sweet trail in the Hudner Ranch portion of Hollister Hills SVRA. It is moderately difficult, and any 4WD or AWD vehicle can complete it. This trail is great for beginners looking to get experience offroad. The trail is made up of loose dirt with some steep hills and sharp turns. Portions of the trail are overgrown, and pinstriping is likely from the branches and bushes that have grown onto the trail. There is no camping directly off of the trail, but there are campsites available in Hudner Ranch that require a prior reservation.
