The Twin Peaks Bioregion is the hilly heart of San Franciscoâthe top of the city's watershedsâfrom the oak woodlands of Golden Gate Park to Glen Canyon, and from Hawk Hill to Buena Vista Park. Nature in the City has been talking for a couple of years about the heart of the city as a special place to which we should pay attention. Our vision for a Twin Peaks Bioregional Park would consolidate 10-12 different City jurisdictions into one management entity for the protection, restoration and connectivity of one of the most open space and biodiverse rich parts of San Francisco.
