20. Arrowhead Marsh, Oakland, California

Find shorebirds, raptors, and other birds just minutes from San Francisco’s Bay Bridge.

A pleasant surprise always awaits at Arrowhead Marsh. Despite its urban location, I face quiet water and a shoreline filled with hundreds to thousands of birds.

Consisting of more than 50 acres of restored salt marsh, Arrowhead is part of the 1,220-acre Martin Luther King Jr. Shoreline, a jewel of the East Bay Regional Park District. Narrow channels connect shallow San Leandro Bay with the broad waters of San Francisco Bay farther west. Protected from high waves but subject to strong tides, Arrowhead’s mudflats and salt marsh provide rich bird habitat, and the park service is eradicating introduced spartina plants, making the marsh even more attractive to birds.

I look for three rail species at high tide and hordes of wintering shorebirds on the mudflats at low tide. In the summer I can find 40 species, including many newborn stilts and avocets, and it’s possible to top 60 species on a fall or winter day. Almost any Pacific shorebird or raptor is possible during fall migration. — Harry Fuller

From Oakland, take I-880 (Nimitz Frwy.) south to Hegenberger Rd. and turn right. Drive about a mile to Doolittle Dr. and turn right. After a third of mile, turn right again onto Swan Way. Then make your first left and follow the road into the wetlands.
