Mason Rocks
Why dive here
With 71+ marine species recorded in the area - including barracuda and pufferfish - Mason Rocks offers some of Malpelo Island's richest reef diving. Water ranges 28-30°C, warmest September, October, November.
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.
