Channel Islands National Park Essentials

Channel Islands National Park encompasses five distinct islands: Anacapa, Santa Cruz, Santa Rosa, San Miguel, and Santa Barbara. This archipelago serves as a sanctuary for over 2,000 plant and animal species, including the endemic island fox. Key landmarks include the 1932 Anacapa Island Light, the dramatic cliffside viewpoint at Inspiration Point, and the 1853 wreck of the SS Winfield Scott. The islands feature diverse terrain ranging from the sea caves of Anacapa to the historic 19th-century masonry of the Scorpion Adobe ranch house.
