San Francisco's urban national park unit recently gained 14 acres with the opening of the Presidio Tunnel Tops, a green space designed by James Corner Field Operations, the lead firm for New York City’s High Line, which incorporated input from more than 10,000 residents with the help of the Parks Conservancy.

Two dozen parks have opened in San Francisco since 2020, including what The Chronicle calls "the spectacular Presidio Tunnel Tops," a triumph of imagination and generosity of Bay Area donors. Tunnel Tops cost $118 million — $98 million of which was raised by the Golden Gate National Parks Conservancy.

Allen Fish, Director of the Golden Gate Raptor Observatory--a long-term, community-science program of the Golden Gate National Parks Conservancy, in cooperation with the National Park Service--tells us all about their hawk count and banding operation, as well as some of the fascinating projects and partners that connect to this community science effort.

For an inspiring, all-ages journey, gather around a campfire with Golden Gate views at Presidio Tunnel Tops in San Francisco.
