The Blue Hole

The Blue Hole is one of the most iconic and beautiful dives on Earth, a near-perfect circular sinkhole dropping vertically from 6 m to beyond 130 m. You enter through a short shallow reef garden, then the floor simply disappears and the water turns an impossibly deep indigo. The outer wall of the Blue Hole is draped in pristine hard and soft corals, and you share the water with clouds of glassfish, hunting trevally, and the occasional oceanic whitetip passing below the thermocline. The famous arch at 52 m connects the hole to the open sea, a passage reserved for divers with advanced trimix training. Staying above 40 m on the inside wall still delivers an experience that is hard to describe and impossible to forget.
