Don Edwards Wildlife Refuge

Established in 1947 this refuge includes a lot of the marshy shoreline on the southern end of San Francisco Bay. It's a great place to observe wildlife, being the stopping place of migrating birds. In fact, over 280 species of birds use this refuge area throughout the year, including ospreys, eagles, and white pelicans. It's one of six wildlife refuges in the San Francisco Area. Free to visit, it's a popular place for locals. There isn't much shade, so visiting in the morning is recommended.
