"Located in Playa del Carmen within a protected natural park about an hour from Tulum, this cave cenote requires a guided tour for safety and ecosystem protection; tours (starting around $50 per person) include background on the cenote’s history and geography as well as snorkeling gear and a wetsuit, making it a good choice for visitors interested in cave swimming and learning." - Patricia Doherty Patricia Doherty Patricia Doherty is a writer who specializes in covering destinations, resorts, and cruises for Travel + Leisure and other publications.
