Is it Safe to Swim in Cenotes in Mexico? What You Should Know

Whether you're an adventurous or a cautious swimmer, it's natural to have questions before diving into a cenote. These natural freshwater pools have captured the imagination of visitors from around the world because of their breathtaking appearance and the part they play in ancient Mayan history, but are cenotes dangerous? 

We’ll answer that question in detail and help you decide whether or not you should take the plunge. 

What is a cenote? 

Cenotes (pronounced seh-no-tays) are natural sinkholes filled with fresh water, formed over thousands of years as limestone bedrock collapses and exposes the groundwater below. The area of Mexico called the Yucatán Peninsula is home to thousands of them.

Cenotes are more than just geological wonders. They were sacred sites to the ancient Mayans, who considered them spiritual portals to the underworld and used them for offerings and ceremonies. 

There are four main types of cenotes, each offering a different swimming experience: 

1. Open cenotes: Exposed to the sky, often resembling natural lagoons or pools 
2. Semi-open cenotes: Partially covered with dramatic light filtering through the ceiling or surrounding trees 
3. Cave cenotes: Enclosed within caverns, perfect for those who love adventure and mystery 
4. Underground cenotes: Completely hidden and only accessible through caves or tunnels 

Are cenotes dangerous? 

Despite their otherworldly appearance, cenotes are very safe for swimming, especially in areas popular with tourists like Cancun, the Riviera Maya, and Tulum. There are usually no dangerous animals in cenotes that are open to the public. There are also no strong currents. Cenotes are fed by underground rivers, so the water movement is gentle or nonexistent. 

That said, not all cenotes are created equal. Some are remote or undeveloped, which may come with unpredictable terrain, slippery rocks, and a lack of signage. That’s why guided tours and monitored cenotes are the safest option, especially for beginners. These areas typically offer well-maintained paths and stairs, staff on-site to assist visitors, and marked swimming zones. 

To add even further to your comfort and safety, if you need transportation, Seasons Tours will help you arrive at the cenote of your choice.
