From Ranchita take the right past the Anza Borrego State Park sign on the dirt road Jasper trail. Once you get to a four way cross turn left and follow it till you reach the Culp Valley camp. A display sign will be at the camp parking, can't miss it. From Culp Valley main area follow the road south till you see the parking area. If you take the road from Ranchita you may be able to get away with a low clearance car, if you are coming from Culp Valley main area you will definitely need a high ground clearance vehicle.
