The Don Edwards S.F. Bay National Wildlife Refuge is over 30,000 acres of open bay, salt ponds, salt marsh, mudflats, etc. located on the southern end of San Francisco Bay. There are a few ways to get to the refuge. Two ways to access the refuge are:

Alviso

I have been a couple time to the Alviso entrance to the NWR. They have an Environmental Education Center with some nice walks. There were a lot of shorebirds, terns, etc.

Thornton Avenue

The Refuge Headquarters and Visitor Center is in Fremont off of Thornton Avenue. I have only been there once, and while interesting, I did not see as many birds as Alviso.
