Gran Cenote

Gran Cenote, just outside Tulum, is a partially open limestone sinkhole famed for clear, turquoise water and dramatic cave formations. Snorkelers glide over lily-fringed pools to view stalactites and small fish; divers explore connected caverns on guided dives. Wooden walkways, platforms, and basic facilities make access easy, though crowds and higher fees reflect its popularity. Turtles are often seen, and visibility is excellent in the morning. It’s ideal for travelers seeking cenote swimming or an introduction to the Yucatán’s underground rivers; those wanting solitude may prefer lesser-known cenotes.
