"Part of the world’s longest underwater cave system (over 200 miles), this cenote—sometimes nicknamed for fossil and pottery finds—features spectacular limestone formations, stalactites, and stalagmites. It tends to be less-touristed than more famous sites and offers parking, gear rental, and restrooms with admission or by booking a private cave-diving tour." - Patricia Doherty Patricia Doherty Patricia Doherty is a writer who specializes in covering destinations, resorts, and cruises for Travel + Leisure and other publications.
