Guadalupe Island is a volcanic island located 241 kilometres off the western coast of Mexico's Baja California Peninsula and about 400 km southwest of the city of Ensenada in the state of Baja California, in the Pacific Ocean. The various volcanoes are extinct or dormant. In 2005 Guadalupe Island and its surrounding waters and islets were declared a biosphere reserve to restore its vegetation and to protect its population of marine mammals and birds.
