Cave dive in Cenote Zapote in Puerto Morelos. Video was shot at a depth of 130 feet. This cenote has some of the most magnificent formations we've ever seen. Some call them sprinkler heads, shower heads, elephant feet, but we like to call them Hell's Bells. There is a thick hydrogen sulfide layer at approximately 90 feet. Cavern diving is possible, but since this is a deep sinkhole, for this dive a diver must be at minimum AOW certified with better than average buoyancy control and deep diving experience. check out beyonddivingscuba.com for more information!
