The park's campground on the west side was demolished by El Niño storms in 1997 and 1998, and it's not scheduled for repair. Now the only campground is the privately run Pinnacles Campground, Inc., on the east side (tel. 877/444-6777; www.nps.gov/pinn/planyourvisit/camp.htm), which charges $23 per tent and $36 per RV. It's just outside the park (off Hwy. 25, 32 miles south of Hollister), with lots of privacy and space between sites, plus showers, a store, and a large pool. It's close enough so you can hike into the park from the campground, though it will add a few miles to your outing. Surroundings here are natural rather than overdeveloped.
