Cenotes of the Riviera Maya Travel Guide
Cenotes are natural sinkholes in the Yucatán's limestone shelf — windows into the underground rivers that drain the entire peninsula, including Sac Actun near Tulum, one of the longest underwater cave systems ever mapped. There are thousands of them, and no two are alike: fully open pools ringed by jungle, semi-open wells with light beams at midday, and cavern cenotes where you swim between stalactites. The water is filtered rainwater: fresh, clear, and cool year-round, which makes cenotes the classic midday break between beach and ruins. Famous names include Dos Ojos and Gran Cenote near Tulum, Ik Kil beside Chichén Itzá, and Suytun with its photogenic light shaft. Most cenotes require biodegradable sunscreen — or none at all — to protect the water.

Frequently asked questions
What exactly is a cenote?
A natural sinkhole in the Yucatán's limestone shelf, opening into the underground rivers that drain the peninsula. They range from fully open jungle pools to caverns where you swim between stalactites.
Do I need to know how to swim to visit a cenote?
It helps, but most organized cenote visits provide life jackets — many sites require them — and shallow entry areas. Guided tours pick cenotes to match the group.
What should I bring to a cenote?
A towel, water shoes, and biodegradable sunscreen — or none at all, since most cenotes prohibit regular sunscreen to protect the water. A waterproof phone case earns its keep.
