Explore one of the Bay Area’s most important wildlife refuges with miles of walking tracks, a fishing pier, and plenty of opportunities to spot local and migratory birds. More than 200 types call the area home, including protected species such as the California clapper rail bird and the California brown pelican.

Walk one of dozens of tracks that total over 30 miles (48 kilometers) and cover nearly every habitat in the 30,000-acre (12,140-hectare) refuge. Most are graveled and good for novice hikers, and many offer benches and shaded areas to rest and admire the panoramic vistas.

Binoculars and telephoto lenses are a must for anyone interested in ornithology. Thousands of migratory birds spend the winter in the area, and over 500,000 shorebirds are said to forage in the mudflats and ponds. Keep your eyes peeled for non-feathered creatures too, like the endangered salt marsh harvest mouse, lizards and harbor seals.

Wander out along the pier and cast your gaze out to the bay. In the waters are bass, sturgeon and leopard sharks. Fishing enthusiasts are welcome to sink a line, but be sure to note local fishing regulations before taking anything home.

Drop by the visitor center in nearby Fremont for detailed information about the refuge and its inhabitants. You can also book a class at the Environmental Education Center in Alviso to learn about the refuge’s wildlife and ecosystems.

The Don Edwards San Francisco Bay National Wildlife Refuge is open daily and entry is free. You’ll need a car to get there, but parking is easy and affordable. The refuge changes in character and appearance according to the season, and in winter the wind can be particularly biting. Check the weather forecast before heading out.
