POST protects open space on the San Francisco Peninsula and in the South Bay for the benefit of all. Since 1977, we've worked hard to permanently protect lands for hiking and recreation trails, wildlife habitats, redwood trees and local farms—all of which make our region extraordinary.
We want people to get out and enjoy these amazing local landscapes, so we host all kinds of community events—and we'd love for you to join us! See our full list of hikes, film screenings, lectures and more.
We're an accredited land trust and a 501(c)(3) nonprofit organization, which means we're funded by the generous support of private individuals and foundations.
POST-protected properties are all around: Windy Hill, Mindego Hill and several others off of Skyline Boulevard; Tunitas Creek Beach in Half Moon Bay; Bair Island in Redwood City; Whaler's Cove by Pigeon Point in Pescadero; parts of Coyote Valley in San Jose; and many more.
