The archipelago’s largest island, Isabela, was formed by the joining of five young volcanoes. While these volcanic regions contain extensive lava fields and little vegetation, the southern highlands and various other regions are covered by dense vegetation including the unique red mangrove. Isabela Island is also home to many native Galapageños living in the island’s largest town, Puerto Villamil.
