Diving is good in Eleuthera because of a few reasons; the clear water, and the proximity of the many reefs to the shoreline, especially on the Atlantic side. For snorkelling, you can do this from almost anywhere in the island.
DIVE SHOPS
The dive shops are concentrated in Harbour Island, where there is a concentration of good deep-sea diving sites. Because of the dangerous reefs in North Eleuthera, there were many wrecks, which are great for exploring.
DIVE CHARTERS
Things are very laid back on the island, and you can hook up with almost anyone with a boat, who will take you both diving or fishing. The formal charters are listed on this link in Harbour Island and the mainland of Eleuthera
DIVE SPOTS
As previously stated, you can dive from the shore, or beach. There is a concentration of excellent dive sites near Harbor Island, if you are interested in exploring wrecks. Near the small island of Spanish Wells is the 'Devil's Backbone', an area which has many wrecks, old and modern. Also nearby is the 'Eleuthera Train Wreck', where the wreckage of railroad cars lays, from the era of the Civil War. There is a 1919 freighter, 200 feet long nearby, in about 35 feet of water. Finally, there is a 265 foot freighter, that sank in 1971 to explore in the same general area. Also, note the famous "Current Cut Dive", which allows you to drift at high speeds at the change of the tide.
BAHAMAS REEF FISH
