Diving in Cenotes: discovering the Mayan Underworld

About

Cenote diving takes you into flooded limestone caves south of Cancún, part of the world's longest underground river system. This particular trip runs five hours and includes two cenote dives — you'll need your open-water certification and ideally some buoyancy control, since the overhead environments and tight swim-throughs don't forgive sloppy finning. The light shafts through the ceiling openings are the main visual payoff, along with the clear water and occasional stalactite formations. The $285 price point puts this in the mid-to-upper range for cenote dives leaving from Cancún, and the perfect rating across ten reviews suggests the guide work is solid. Expect a drive of 45 minutes to an hour each way, depending on which cenotes the operator runs that day. Most trips provide weights and tanks but not wetsuit or dive computer, so confirm what's included when you book.
