About The Blue Holes

Blue Holes consists of four uniquely formed blue holes in the reef that drop into a large cavern. The fish even swim upside down on the ceiling! Designed like any good auditorium, there are exits in the wall allowing for a continuing dive down to you guessed it - Blue Corner, the other prime hotspot in the area. This geological anomaly delivers a cavern plus drift plus wall dive, yet another addition to the Advanced level diver's dream. It also includes areas easier to dive than Blue Corner. There is a large and small exit on the reef face. The larger one leads to a narrow opening through which a cave known as the Temple of Doom is found. The unfortunate name originates due to the lives it has claimed. Needless to say, this is where trained cave divers take over and guides and special gear are required if you want to live to tell that tale about that massive Grouper... In the inside of the cavern, light streams in and visibility ranges from 45 to 120'.
