Cenotes are one of the most magical parts of visiting the Yucatán Peninsula — but because they're also fragile freshwater ecosystems connected to the region's only water table, a few rules apply that don't at a regular pool or beach.
Sunscreen matters — a lot
Regular sunscreen contains chemicals like oxybenzone that are toxic to the delicate cenote ecosystem. Only biodegradable, reef-safe sunscreen is allowed before entering the water. If you don't have any, no problem — just apply it after your swim instead, or ask our guides for guidance.
What to bring
- A swimsuit (worn under your clothes saves time)
- A small towel
- Water shoes if you have sensitive feet — cenote floors can be rocky
- Biodegradable sunscreen, if you plan to reapply
Getting in and out
Some cenotes are entered via stairs, others via a short jump or ladder — our guides will walk you through your specific cenote's access point and depth before you swim. Life jackets are available for anyone who wants one, regardless of swimming ability.
Respecting the cenote
No touching the rock formations, no littering, and no chemical sunscreens or bug spray in the water — these simple rules keep the cenotes clear and swimmable for everyone who visits after you.
