Socorro Island
Island Volcanic island in Revillagigedo known for diving
The largest of Mexico’s Revillagigedo Islands, Socorro draws liveaboard divers for pelagic encounters-hammerheads, manta rays and humpbacks-and for rare endemic birds and rugged volcanic coastline.
Socorro Island is a volcanic island in the Revillagigedo Archipelago, administered by the state of Colima, Mexico. It is the archipelago’s principal island and is notable for its marine biodiversity.
Socorro is volcanic in origin and has been used intermittently for naval and scientific purposes; human presence on the island has been small and related mainly to those activities.
The island lies in the eastern Pacific as part of the Revillagigedo group, remote from the Mexican mainland and reached principally by sea from mainland ports or via organized dive expeditions.
- Diving and marine life: Part of Mexico's Revillagigedo National Park, the island is renowned for pelagic marine life and is a destination for liveaboard scuba diving focused on large pelagic species.
