Safety
At Kris Cros Diving, safety is our number one priority. All tours are designed and conducted in accordance with local community safety regulations, as well as dive agency rules and standards.
Tulum offers a highly unique underwater environment that allows for recreational cavern diving. The cavern zone is the visible light zone at the opening of a cave. Cavern divers will always be able to see natural light from any point on a cavern dive, and always remain within 60m/200ft of open water.
Because cavern diving is performed in an overhead environment, emergency ascents cannot be performed, and divers must exit a cavern completely in order to reach open water. To maintain optimal safety for all divers, local dive guides follow a thorough set of local regulations which differ from general open water standards:
​
-
Maximum of 4:1 guide to diver ratio. Some advanced sites have a 3:1 guide to diver ratio.
-
Conservative gas management: The Rule of Thirds. Divers will manage their usable gas by dividing it by 3 and should use no more than one third for the way in, one third for the way out, leaving at least one third in reserve.
-
Fixed cavern lines for visual reference.
-
Single-file swimming configuration, with guide always in front.
-
Mandatory use of dive lights.
-
Prohibited use of knives, gloves, and snorkels.
-
No entering caves.
Please note: cenote diving can be more physically demanding than boat diving. At most dive sites you will have to carry your equipment up and down stairs, often a few minutes walk between the vehicle and the cenote entry point. If you will need or would prefer additional assistance, please let us know in advance and services can be provided.
