The sheer number of dive sites, each one unique, makes the Cayman Islands a superlative destination for divers. A few of the opportunities include wall dives, coral dives, cave dives and reef dives. The best part is that underwater visibility is up to 100 feet. To the southeast, the Cayman Islands are surrounded by the Cayman Trench, the deepest point in the Caribbean between Cayman and Jamaica. Its northernmost edges form the Cayman Ridge, which drops to 25,000 feet in places. The Cayman Wall drops off as close as 100 yards from the shore, offering breathtaking views of living coral reefs.
