There are over 100 miles of trails which accommodate hikers, bikers, and equestrians. The two family camps, Paso Picacho and Green Valley, are open and on the reservation system spring through fall. Green Valley sits at an elevation of 4,000 feet and has a creek which runs through the middle of the campground. The day use area offers sets of cascades and shallow pools, great for water play on hot days.
East of San Diego, the park is on Highway 79, five miles north of I-8.
