The best part is the viz. but also you all the colors from the minerals. You feel traveling into the past. Then you start looking at the rock formations stalactites and stalacmites. The formation of this speleotherms is very, very slow. 100 year just for a few inches. In some cenotes you can find really big ones. The longest stalactite found under the water is 60 ft long.It is located in the downstream of cenote chac-mool, in the cave area. Takes you like 40 minutes to get there in a section called the monster`s house. I took this pic at cenote chac-mool, in the kukulcan cavern area. I hope you like it. Take care and safe diving.
