The rocks are named after Don Victór 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.[3] There are also sometimes sea lions on the rocks.[4] The rock's Harbor Seals also frequent Mowry Slough, Brooks Island, Yerba Buena Island, and Mare Island.[5]
