Key Facts

Isabela is the largest island in the Galápagos archipelago, located approximately 1,000 kilometers off the coast of Ecuador in the Pacific Ocean. Named after Queen Isabella I of Spain, this volcanic island spans approximately 4,640 square kilometers, making it larger than all the other Galápagos islands combined. Situated on the western edge of the archipelago, Isabela was formed by the merger of six shield volcanoes—Ecuador, Wolf, Darwin, Alcedo, Sierra Negra, and Cerro Azul—five of which remain active, creating a dramatic landscape of rugged terrain, lava fields, and pristine beaches. The island is divided into several key areas, including Puerto Villamil, the main settlement, and the highland regions surrounding the volcanoes. With a population of around 2,200 people, primarily concentrated in Puerto Villamil, Isabela is known for its unique biodiversity, including giant tortoises, marine iguanas, and blue-footed boobies, and is a critical part of the Galápagos National Park and UNESCO World Heritage Site.
