A long, narrow spit of sand, bound between Drakes Bay and an estuary, is a bountiful wildlife area. Scores of shorebirds feed in the wetlands and along the beaches during the fall. Ducks abound in winter at old, freshwater stock ponds created during the peninsula's ranching era. Harbor seals are often seen bobbing offshore in the gentle waves or basking in the sun's warmth. Mother gray whales guide their calves along the shoreline during the spring. Dogs are allowed on a 1.8-meter (6-foot) leash on the southeast end of this beach. Dogs are not permitted to the northwest as this area is protected habitat for harbor seals and the endangered snowy plover.
