5 mile loop

Amenities and Uses
Parking, restrooms and drinking water nearby at the Visitor Center, hiking, bicycling. No pets.

Trail Surface
Mostly flat, compacted dirt levee. Turns to mud after rain.

This trail traverses the most common habitat types in the refuge: tidal marsh, tidal slough and salt ponds. The tidal marsh is home to endangered Ridgway’s rails and salt marsh harvest mice— two species only found in San
Francisco Bay— and the Alameda song sparrow, a Species of Concern in California. Northern shovelers, shorebirds, and grebes fill the pond in the winter while Forster’s terns and American avocets use the pond in the summer. There are excellent views of the dominate salt marsh vegetation such as pickleweed, Pacific cordgrass and gumplant which has yellow flowers late into the summer.
