Castro Rocks are several rocks in Richmond, California protruding from the waters in San Francisco Bay between Castro Point and Red Rock Island.The rocks lie almost directly under the Richmond-San Rafael Bridge (Interstate 580).
Castro Rocks are the home of many harbor seals and who lie on them to rest and sunbathe. The rocks are named after Don Víctor Castro a local rancho-era land owner. The rocks are the largest harbor seal rookery in the northern San Francisco Bay and the second largest in the Bay Area itself. There are also sometimes sea lions on the rocks. The rock's Harbor Seals also frequent Mowry Slough, Brooks Island, Yerba Buena Island, and Mare Island.
The seals at this location have high levels of toxic pollutants including the DDT, PCBs, PBDEs, PFOS, PFOA, and mercury.
