Tidal freshwater blue holes are unique to the Bahamas and South Andros Island offers the highest concentration of Blue Holes in the world. Inland and offshore blue holes can exceed 400’ of depth. Blue Holes were formed during the last ice age when ocean levels were 300-400’ lower. Rainwater and eventually seawater eroded the limestone foundation of the island and created these spectacular caverns in a variety of shapes and sizes.

A recent National Geographic cover story featured the Bahamas Blue Holes including Stargate Blue Hole of South Andros Island.
