Cenotes are natural sinkholes or cave systems filled with crystal-clear freshwater, formed when limestone bedrock collapses to reveal the underground rivers below. The Yucatan Peninsula of Mexico is home to an estimated 6,000 cenotes — one of the highest concentrations of these natural wonders on Earth. They were sacred to the ancient Maya, who used them as sources of drinking water, for ceremonial offerings, and as portals to the underworld.
Today, cenotes are among Mexico's most extraordinary natural attractions. Whether you're looking to snorkel through ancient cave systems, dive into crystal-clear open-sky sinkholes, cliff jump into turquoise pools, or simply swim in the cool freshwater away from the Caribbean crowds — the Yucatan's cenotes offer something for every type of traveler.
This directory covers 190+ cenotes across 11 regions including Tulum, Valladolid, Playa del Carmen, Merida, Chichen Itza, Coba, Bacalar, Puerto Morelos, and Izamal. Use the filters to find cenotes by type (open, semi-open, or cave), activity, difficulty level, and entry fee.
The word "cenote" comes from the Maya word ts'onot, meaning sacred well. Cenotes form when porous limestone rock collapses, exposing the vast underground river network that runs beneath the entire Yucatan Peninsula. The water is fed by rainwater filtered through the jungle and is exceptionally clear and cool — typically around 24°C (75°F) year-round.
Cenotes are found throughout the Yucatan Peninsula — in Quintana Roo, Yucatan state, and Campeche. The highest concentrations are near Tulum, Valladolid, and Merida. Some of the most famous include Gran Cenote, Dos Ojos, Ik Kil near Chichen Itza, Cenote Suytun, and the vast Sac Actun cave system — one of the longest underwater caves in the world at over 347 km.
Always use biodegradable sunscreen — regular sunscreen damages the delicate ecosystem. Many cenotes require life jackets, especially in deeper pools. Cave cenotes can be dark so bring a waterproof flashlight. Entry fees are typically 80–300 MXN ($5–$18 USD). Most cenotes are open 9AM–5PM but hours vary. Always verify locally before visiting as conditions change seasonally.
