Chub Hole

Grand Cayman East
Why dive here
With 327+ marine species recorded in the area - including barracuda, bull sharks, oceanic whitetip sharks, orcas and sea turtles - Chub Hole offers some of Grand Cayman's richest wreck diving. Water ranges 27-31°C, warmest August, September, October.
Chub Hole is pure Grand Cayman magic, an absolute standout for us. You drop onto a mini-wall that’s less a wall and more an architectural marvel, carved with tunnels and archways. We love drifting through them, feeling that slight temperature drop as you enter, then emerging to a burst of sunlight. It’s like a secret passage tour. North of the wall, the reef opens up, towering coral fingers reaching towards the surface. Keep an eye out for the Bermuda Chubb, of course, they hang out in the canyons, often with sleepy Tarpon. Visibility here is usually fantastic, often pushing 25 meters, so you can really appreciate the sheer scale of the coral formations. Look for juvenile fish clouds shimmering above the coral, a real visual feast. It's a relaxed dive, perfect for photographers wanting to explore nooks and crannies without deep deco concerns, and we'd say it’s best enjoyed mid-morning before any crowds arrive.
