The Yucatan Cenotes

Cenotes are the magical natural sinkholes of the Yucatan, pools of crystal-clear fresh water in collapsed limestone, ranging from open jade pools to vast flooded caverns hung with stalactites and pierced by shafts of light. Sacred to the ancient Maya as gateways to the underworld and sources of water, thousands are scattered across the peninsula, and swimming, snorkelling or diving in their cool, clear water is unforgettable.

What's there

• The open cenotes - the jade pools open to the sky and jungle.
• The cavern cenotes - the underground caverns of stalactites and light shafts.
• Swimming and snorkelling - the cool, clear water for a refreshing dip.
• Cave diving - the flooded cave systems for experienced divers.

When to go

November to April for the driest weather and clearest water, though the cool water is refreshing in the heat any time. Go early to have the popular cenotes before the tour crowds arrive; weekdays are quieter.

Things to know

The famous cenotes near the resorts get crowded and can feel commercialised, so seek out quieter, lesser-known ones for magic. Sunscreen is often banned to protect the water, so shower first and cover up instead. Some are deep with no shallow end, so they suit swimmers.

Nearby

Chichen Itza, Valladolid and the Riviera Maya coast are all dotted with cenotes.
