The Presidio of San Francisco is a 1,491-acre former US Army installation in the northwest corner of the city, at the south end of the Golden Gate Bridge, transferred to the National Park Service when it was vacated by the military in 1994.
Today, the Presidio is a thriving urban park with a unique mix of residential communities, businesses, historic sites, recreation areas, forests, grasslands, beaches and bluffs, connected by a network of hiking and biking trails.
In 1996, after considering a sale of the Presidio, it was effectively privatized by transfer of its management to the Presidio Trust, a federal government corporation tasked with making the Presidio self-sufficient and independent of direct taxpayer support. The Presidio Trust now manages most of the park, with the National Park Service managing the coastal areas, both working in partnership with the Golden Gate National Parks Conservancy.
