Presidio Tunnel Tops is a free, accessible, and stunning national park space that was built by the community, for the community. We recommend starting your visit at the Presidio Visitor Center, then you can make your way around the beautiful 14 acres to take in the iconic views, sprawling lawns (perfect for picnics!), and all the other exciting features Presidio Tunnel Tops has to offer.
