We've done the eco-parks and Tulum Mayan ruins day tours on our previous trip and had great experiences but recently got a tip from a Mexican friend that the cenotes in the Tulum area are something that everyone needs to experience. We weren't really sure what a cenotes even was but thanx to google and searching in "top three Carribean cenotes", we were quickly captivated by the natural beauty and adventure of exploring these amazing wonders. I guess our question is if anyone has experienced any cenotes tours and can give us a tip or two for a fun and adventurous day tour? As always, we'd be interested in a few couples to enjoy the experience with us...... We're at TTR April 2oth - 27th. D&J
