Sea Eye offers daily diving on the reef wall, which is a short 5-15 minute boat ride from most Grand Turk hotels. Diving is on the leeward side of the Turks Island Passage, a 22-mile wide channel that is over 7,000 ft. deep. This passage separates the Turks Islands from the Caicos Islands and in winter months is the migration route for Humpback Whales headed south to their mating and calving grounds on the Mouchoir and Silver Banks.
