Mary Isabella Reef - Malpelo Island
Mary Isabella Reef offers a solid dive at Malpelo, a good spot if you're looking for reef action away from the main currents. We've often found schooling grunts and snapper here, sometimes a passing whitetip reef shark. It's a calmer alternative to some of the more exposed Malpelo sites, making it suitable for divers who prefer a more relaxed pace.
