El Pit Cenote Diving
Dive El Pit near Tulum, one of the deepest cenotes in the area and famous for its spectacular light beams. Cross the halocline at 15 meters and reach the hydrogen sulfide layer at 30 meters with The Dive Machine’s certified guides.
Light Beams, Halocline and Depth
El Pit is famous for the rays of light that pierce the darkness from the opening above. As you descend, you cross a halocline at about 15 meters, where fresh and salt water meet and blur the view, and at about 30 meters you reach a hydrogen sulfide layer. The cenote reaches about 40 meters, making it a true deep diving experience for Advanced Open Water divers.
