What to know

Presidio Tunnel Tops is a 14-acre elevated park designed by Field Operations that opened to the public in 2022. This innovative green space was built directly on top of the Presidio Parkway tunnels, effectively connecting the Presidio Main Post with Crissy Field by creating parkland and vista spots over a roadway corridor. Since its opening, the site has welcomed over 5 million visitors, establishing itself as a primary entry point to the national park site. At the heart of the experience is the Field Station, a free public curiosity lab. Here, visitors are encouraged to use their senses to explore real objects sourced from the Presidio. Located next to the Outpost nature playground, the Field Station provides a tactile way to engage with the local environment without the need for tickets or reservations. The park is designed for diverse recreation, offering picnic sites, food vendors, and the Outpost Meadow expansion located on the west side near Sports Basement. The area hosts a consistent calendar of year-round events, ranging from guided nature walks and cultural festivals to outdoor fitness classes. Located at 210 Lincoln Boulevard, the park remains free and open daily.
