Join Discovery Channel as it dives to the bottom of the Legendary Blue Hole, the largest submerged sink hole in the world.

What is inside this 30-million-year-old, 412 ft deep and 984-foot-wide mystery? Forty-six miles off the coast of Belize, the Blue Hole, its crystal-clear waters filled with an abundance of sharks, has only ever been properly explored once before: by the legendary Jacques Cousteau himself back in 1971.

But it has never been mapped, it has never been plotted and we have absolutely no idea what lies at the bottom of it.

On December 2nd, we will be building a two-hour special around the Blue Hole Live in a Stingray 500 manned submersible. On board will be Sir Richard Branson, Jacques Cousteau’s grandson, Fabien Cousteau, and the submersible pilot Erica Bergman. They will be attempting to take their submersible to the bottom of the blue hole.
