Why dive here
With 207+ marine species recorded in the area - including barracuda, lemon sharks, seahorses, sea turtles and sperm whales - Mariner Shoal offers some of Corn Islands's richest reef diving. Water ranges 27-30°C, warmest May, September, October.
Mariner Shoal is a solid dive, a good place to spend an hour underwater in the Corn Islands. We’ve seen puffers hanging around the coral heads and often spot green turtles gliding past, sometimes a hawksbill or even a loggerhead. It’s a straightforward dive, well-suited for divers who appreciate a relaxed pace and reliable turtle sightings.
