Pulgas Ridge Open Space Preserve is a small, well-managed public and recreation area with a large off-leash dog area in the Santa Cruz Mountains. Formerly a tuberculosis sanitarium owned by the City of San Francisco, the 366-acre park still boasts some old retaining walls and steps from the buildings but has now been cleared of all foreign vegetation and has more than six miles of hiking trails with access to cool canyons and beautiful views of the bay and surrounding hillsides from a ridge top. The trails are dog-friendly, and there are plenty of areas for dogs to run and play on and off-leash. Pulgas Ridge Open Space Preserve is open from dawn to half-an-hour after dusk.
