Presidio Tunnel Tops is a new area within the Presidio national park site, free and accessible to all and opening starting July 17, 2022. Built on the Presidio Parkway tunnels, these 14 acres of outdoor space with educational facilities connect the historic center of the park to the Presidio’s waterfront at Crissy Field. Learn more about site features and how Presidio Tunnel Tops was designed and shaped by our community. This project was made possible by achieving a $98 million campaign goal to build a world-class parkland. Our thanks to the incredible generosity of our donors and members of our community.
