Located in the Tennessee Valley in the north end of the Marin Headlands (a gentle three-quarters of a mile walk from the Tennessee Valley parking area), Haypress Campground has five sites that can accommodate up to four people each. The campground does not have water, so campers need to pack everything in. No wood or charcoal fires allowed, but gas camp stoves are permitted. For larger groups, the entire campground may be reserved, but be aware, the maximum stay is three nights per year. The campground is free, but reservations are required, and can be made by calling (415) 331-1540 from 9:30 AM - 4:30 PM.
