Florida Keys Dive Sites - The Blue Hole

Slopes gently from a depth of 30 ft. down to the sandy seafloor - depth 70 ft. To find the Blue Hole itself -  look for two sand chutes running from the slope of the reef to its base; south of the chutes a type of mound thrusts its way upwards out of a deep canyon. The seafloor is of clean sand, without the well-developed staghorn and elkhorn colonies observed elsewhere.
