Mayan Blue





This is a deep cenote compared to most other systems in this area. Not that really deep compared to open water diving. But in the context of an overhead environment, depth brings another variable to the safety equation. Your normal 1 hour+ dives of other cenotes will send you into decompression obligations, which adds complexity. The higher rate of gas consumption at depth is also another item that must be considered.

The Surface


The tunnels we visited go down to 28 meters. To minimize our decompression schedule, we dove nitrox @ 41% O2. On the first dive, we went thru Tunnel B from the entrance. Click on the map to get a higher resolution view. I used a lot of gas as there was a little current running and turned around the dive before the agreed time was due.

On the second dive we took tunnel A @ 18 meters, made a jump down to the death arrow passage, which lies 10 meters below. The passage, filled with warmer salt water, was much clearer than the Tunnel A above. The decorations were chalk white and pristine. Beautiful place to visit. At the end we jumped up back to tunnel A and to a somewhat hazier, and cooler fresh water. Turned right and went for a few hundred meters before returning the dive.
