Aleutian Goose Festival, Humboldt Bay National Wildlife Refuge

Castle Rock, part of the National Wildlife Refuge System, is the 2nd largest seabird colony in California and the 3rd largest in the lower 48 states. Spotting scopes are strongly recommended to view this large offshore island from the pullout or the bluff top (a short hike).  Eleven seabirds breed here: more than 80,000 Common Murre, Leach's Storm-petrel, Cassin's Auklet, Brandt's Cormorant, Western Gull, Pigeon Guillemot, Pelagic Cormorant, Rhinoceros Auklet, Fork-tailed Storm-petrel, Black Oystercatcher, and Tufted Puffin. May to July is the best time to experience breeding activity. In late-March, the annual Aleutian Goose Festival: A Celebration of Wildness in Crescent City coincides with thousands of Aleutian Cackling Geese using Castle Rock as a primary spring staging ground. See spectacular fly-offs at dawn. View the Rock upclose by charter, see St. George Reef (Pelagic site) description.
