Cenote Snorkeling in Playa Del Carmen is possible at several of the nearby cenotes but some are better than others. I have heard different estimates but I think it is safe to say there are more than 6000 cenotes in the Yucatan. Cenotes , of course are underground springs, caverns, or swimming holes that sometimes form amazing rock formations or can be great swimming hole destinations with fresh, clean water sometimes high in minerals healthy for the skin.
There are basically two different kinds of cenotes that I have visited while living in Playa Del Carmen and traveling around the Yucatan Peninsula and Mayan Riviera. There are cavern/cave type cenotes and swimming hole type cenotes. I love them both and have visited many of both kinds. When the weather cooperates the swimming whole kind are great for cooling off and enjoying a day to swim and relax but there is not much to see underwater at this kind of cenote. My favorite Playa Del Carmen cenote for swimming is Cenote Azul. It is 1 of 3 that are all close to each other and only 20 minutes south of Playa Del Carmen. The others are Jardin of Eden and Cristalino. They are all inexpensive to enter and make for a great day of relaxing and swimming in cool refreshing water in the Riviera Maya. It is important to note , however that these cenotes are not the best for cenote snorkeling because they are not deep and do not have interesting stalactite/stalagmite formations like the cavern or cave type cenotes have.
My favorite cavern type cenote in Playa Del Carmen is best explored snorkeling with a guide who can tell you about the history and show you the best secret caverns and places to look you might not see. One day when my best friends were here in Playa visiting we had plans to go to the beach and the weather turned foul. A little cool with tropical rains. Since we did not have a lot of other free time to visit with my friends and wanted to do something fun together we booked the cenote snorkeling tour. It was perfect for a rainy day because we spent our time underground while it was raining exploring the caverns and viewing the awesome underwater rock formations and stalactites. My friends really loved the experience and it did not take all day and was a short drive to get to. As we emerged from the final cavern and returned our snorkeling gear the rain was clearing and the sun was starting to come out for another Playa Del Carmen sunset.
