Anacapa Island is a small volcanic island located about 11 miles (18 km) off the coast of Port Hueneme, California, in Ventura County. The Island is composed of a series of narrow islets six miles long, running in a mostly east-west orientation, five miles east of Santa Cruz Island. The island is composed of three islets: East, Middle and West Anacapa, collectively known as the “Anacapas” by some authors. The islets have precipitous cliffs, dropping off steeply into the sea. East and Middle Anacapa have fairly level areas at their tops, but West Anacapa is wider and reaches an altitude of 930 feet. Middle Island reaches an altitude of 325 feet and East Island is 250 feet at its highest point. All three islands total 699 acres, or about 1.1 square miles.
