Cenote El Pit
The Pit is an impressive sinkhole located in the deep jungle. It is the largest underwater cave in the world and the deepest one ever found in Quintana Roo with a max. depth of 400 ft. This place is just magic: a thick sulfuric cloud around 90 ft., crystal clear water and two light haloclines, 25 ft. and 45 ft. The lights look like surreal lasers. This is a dive reserved for experienced divers due to the required buoyancy control to avoid uncontrolled ascents or descents in depth.
