Go Diving in a Cenote
By Viator, June 2011
Just inland is another diver's paradise - one that is much less famous and less crowded. Here you'll find the world's largest explored network of caverns and cenotes ('natural wells' or 'underground sinkholes' in Spanish), many of which are open to advanced divers on small-group guided dives. What makes these caverns and cenotes so unique for diving? For one, the water is fresh and crystal clear. Second, the familiar salt water corals and tropical sea life are replaced by towering stalactites, albino snakes, eyeless shrimp and freshwater spiders! For divers jaded on saltwater reef dives, a few dives in a cenote are enough to make you a true believer again.
You can organize cave dives through dozens of local dive shops. Be aware that reputable dive companies often require an open-water familiarization dive before heading into the cenotes.
