Don Edwards San Francisco Bay National Wildlife Refuge is one of the premier wildlife refuges in the area. It was founded in 1974, and has since dedicated itself to preserving the habitats for threatened and endangered species, particularly birds. Hiking trails, lookout posts and a fishing pier equip the refuge with ample facilities to keep visitors occupied for a day.

The stars of the show at Don Edwards San Francisco Bay National Wildlife Refuge are its birds. The refuge welcomes over 280 species each year. The best way to see as many birds as possible is to do one of the many walking trails the refuge provides. Between them, these trails cover 12,140-hectares, and take in almost every habitat there is. Trails tend to be manageable for all, and there are plenty of rest stops along the way. However, it's recommended that come armed with decent walking shoes and a few basic supplies if you intend on walking far. Binoculars and a camera will greatly enhance your experience.

Birds you may be fortunate enough to spot whilst on your ramble include shorebirds, wading birds, waterfowl and raptors. One of the most popular residents of the refuge is the California Clapper Rail. A number of rare mammals such as the California grey fox, and salt marsh harvest mouse occasionally put in an appearance too. On the fishing pier, try your luck with the bass and sturgeon.

The Don Edwards San Francisco Bay National Wildlife Refuge hosts visitor activities throughout the year. Canoes and kayaks can be taken out on the bay and its tributaries. The waterfowl hunting season runs from October to January. Free guided tours and walks are laid on at both of the refuge's headquarters, in Fremont and at the Environmental Education Center in Alviso.

The Don Edwards San Francisco Bay National Wildlife Refuge is open every day and is free of charge. Personal transport is required to reach the refuge parking is ample and free. Weather conditions vary throughout the year check the forecast before making your way out.
