Mexico's Yucatan penninsular is home to one of the most intricate and ancient cave systems in the world. Accessible through the entrances of the cenotes, dive beyond the cavern and explor secret passages,  disovering ancient fossils and preserved artifacts, delicate formations, perfect haloclines and even colour changes from staining of tanic acid. Discover the hidden sacred mayan underworld of xilbalba. 

We offer specialized guided cave diving for all divers who are certified cave and training through SSIs extended range program for those who are ready to adventure into the cave world

Guided Cave Dives

The cave system in mexico is very complex with multiple jump points and often the mainline is hidden from the open area to stop those who are not certified taking a wrong turn. With our guided dives we will take a maximum of 3 cave divers per group maximizing your safety but also your experience as we navigate through the intricate channels. Our guides will optimize your cave diving time not just by showing you all the interesting features, but also we provide the transport eliminating the need to rent a car as many of the cave entrances are found off the beaten track along a dirt road, we have developed communications with the landowners who allow access to cave system, and we have all the emergency equipment should anything arise.

​

We offer 2 options for the guided cave diving, we can do 2 cave dives per day or 1 long dive using a stage. Either in backmount doubles or sidemount configuration. If you are nitrox certified then we can supply nitrox 32% in the tanks. For more infomation get in touch.

The extended range full cave certification is broken down into 3 sections: Cavern, Cave and Full Cave.

You will need a minimum of 10 days for all 3 courses, but we can arrange more days if needed or want a day off to rest.
