Don Edwards San Francisco Bay National Wildlife Refuge covers 19,000 acres around the edges of the South Bay from Redwood City to Fremont. The refuge is named after Congressman Don Edwards, who introduced legislation that established the refuge.
The headquarters and visitor center for the refuge is in Newark, south of Hwy 84. The visitor center building is an impressive multi-story wooden structure built on the side of a rocky hill with panoramic views of marshlands and salt ponds, sloughs, and the Bay to the west. There are exhibits on the wildlife, ecology, and history of the area along with a bookstore, auditorium, restrooms, and an observation deck.
There are twilight marsh walks at the Interpretive Center held once a month. You will see various birds as well as (if you are lucky) the endangered
California brown fox.
A must-see especially for Bay area residents!
