Ravenswood Open Space Preserve

Managed by the Midpeninsula Regional Open Space District, the 376-acre preserve safeguards wetland habitat along the bay. Routes accommodate a pedestrian and bicycle trail, skirting vegetation that shelters the endangered Ridgway’s rail and salt marsh harvest mouse alongside visiting sandpipers, dowitchers, and avocets. The grounds divide into distinct sections: a northern stretch features a 0.7-mile easy-access trail near the Dumbarton Bridge approach, while the southern area connects near Cooley Landing.
