The place
About Don Edwards San Francisco Bay National Wildlife Refuge
Established in 1972 and renamed in 1995, Don Edwards San Francisco Bay National Wildlife Refuge protects more than 30,000 acres around the South Bay with about 38 miles of trails refuge-wide.
This guide is limited to the Fremont Visitor Center and nearby refuge landscape. The public Visitor Center is at 2 Marshlands Road; the adjacent headquarters at 1 Marshlands Road is administrative, not the visitor destination.
The Visitor Center is listed Saturday and Sunday from 10 a.m.-2 p.m., vehicle gates from 7 a.m.-7 p.m. and trails from sunrise to sunset. A broader landing-page 7-to-5 module conflicts with the detailed Visitor Center hours; use the detailed split and confirm.
No current official admission or parking fee schedule, disabled-parking inventory or blanket accessible-route contract was found for this Fremont visit. Keep route claims specific and confirm needs with refuge staff.
