Blue Holes And Spectacular Coral Reefs, Andros, Bahamas

Unlike most of the Bahamian islands, Andros's interior has been largely free of commercial development for the tourism industry, preserving much of its natural beauty. Current Bahamian tourism efforts refer to it as the least-explored island in the chain. There are currently efforts being made by the Bahamas National Trust and the Nature Conservancy to establish a national park on the island.
The island is filled with natural beauty. The east coast of Andros Island lies along the Tongue of the Ocean, a deep oceanic trench. In part because of this location, the east coast of the island is bordered by the best developed fringing reef system in all of The Bahamas (and one of the best in the entire Wider Caribbean region), with a vertical drop on many parts of the fore reef plunging to depths of over 1.8 km (5,900 ft). So extensive is this reef system that it is sometimes referred to as a "barrier reef", but it is not a true barrier reef in the strict definition because it contains only a shallow lagoon that is relatively close to shore. As a compormise, some have taken to calling this a "fringing barrier reef"
