Swimming in Cenotes: A First-Timer’s Guide
If a swim in a cenote is on your Mexico bucket list, you are in for something special. Cenotes are natural sinkholes filled with crystal-clear freshwater, formed over thousands of years in the limestone bedrock of the Yucatan Peninsula. The ancient Maya considered them sacred. Today, they are among the most magical places you can swim anywhere in the world.
What exactly is a cenote?
A cenote is created when a cave ceiling collapses and exposes the groundwater beneath. Some are wide-open pools framed by jungle, others are hidden in caverns with dramatic stalactites overhead. The water is famously clear and refreshingly cool — perfect after a morning of adventure.
What to bring
- Swimwear and a quick-dry towel
- Biodegradable sunscreen (regular sunscreen is not allowed, to protect the water)
- Water shoes for slippery rocks
- A waterproof phone case or camera
Tips for first-timers
The water can be deeper than it looks, so a life vest is recommended if you are not a confident swimmer — most tours provide them. Take your time getting in; the cool temperature is part of the experience. And please avoid touching the rock formations, which take centuries to form.
