Mason Rocks - Malpelo Island
Mason Rocks gives you a taste of Malpelo's big animal action, often with fewer divers around than the main pinnacles. We've seen schooling hammerheads cruise by, along with silky sharks making their passes in the blue. Keep an eye out for patrolling eagle rays too. This spot is best for experienced divers comfortable in open water.
