Safety rules for Cavern diving in the Cenotes

All the Cenotes offering the possibility to do a Cavern dive present a board with very clear and explicit pictograms regarding the safety rules for cavern diving. We encourage you to have a look at it and ask your guide what may remain unclear.

– No snorkel       – Gear streamlined and stowed

– Do not remove any stalactite, rock, fossil from the dive site

– No touching, no scratching, do not leave any visible mark

– Divers go behind the guide in a single file, maximum 4 divers per guide

– The guide must be a Divemaster or Dive Instructor in teaching status and be a certified Full Cave Diver

– Manage your Air using the rule of thirds

– Natural sunlight should be visible at all time, do not go beyond natural sunlight

– Follow the guideline at all time, do not go off the guideline

– Adopt good trim, buoyancy and propulsion techniques,

– Do not remove sediment, it might result in the loss of visibility and it is part of the cave formation, so you should treat it respectfully

– Do not pass through restricted area, at all time 2 divers should fit side by side or one on top of each other

– Limit your penetration to 60m/200feet even when sunlight is still visible, you should not pass this distance without proper Cave diving training.


Remember: There is nothing beyond these limits worth dying for! Do not put your life at risk and follow the rules.
