      The Presidio of San Francisco is managed by two federal agencies in partnership: 300 acres along the coast are managed by the National Park Service, while the rest of the Presidio, 1,191 acres, is managed by the Presidio Trust. Both agencies work in close collaboration with the Golden Gate National Parks Conservancy, a non-profit organization that provides indispensable philanthropic and programmatic support.

      The Presidio Trust is an unusual federal agency. In our founding bipartisan legislation, Presidio Trust Act, ​the Trust was charged with operating the park without taxpayer support. Funds earned through leasing homes and workspaces and operating hotels, a golf course, and venues are used for park management and upkeep.

      Over the past two decades, the Trust and our partners have converted this former military post into a welcoming national park site in an urban area. The Presidio is home to a large community of residents and tenants, and offers unique recreation, hospitality, and educational opportunities to people throughout the San Francisco Bay Area and the world.​
