Can I wear insect repellent in a cenote?

Most cenotes strictly prohibit insect repellent, even the natural kind, as it creates an oil slick on the water surface that harms the ecosystem. Shower it off at home before you go.

Should I bring my own snorkel gear?

You can rent it at most sites for 5-10 dollars, but it is often worn out. If you have space, bringing your own mask ensures a better fit and better hygiene.

Do I need a life jacket?

Most cenotes require you to wear a life jacket, especially if you are not a strong swimmer or if the cenote is deep. They are usually included in the entry fee, so don't bother packing one.

What to Pack for Cenote Swimming

Pack high-quality water shoes, a reef-safe sunscreen, and a lightweight dry bag to protect your electronics. These sites are often rocky and require specific gear to ensure you don't damage the fragile ecosystem or hurt your feet.

Select the right footwear. Avoid flip-flops. Most cenotes have slippery wooden stairs or jagged limestone entry points. Buy closed-toe water shoes with a sturdy rubber sole to prevent cuts and falls.
Choose your sunscreen wisely. Standard sunscreens contain chemicals that contaminate the pristine cenote water. You must bring a brand that is 'biodegradable' or 'reef-safe' containing only zinc oxide or titanium dioxide. Many cenotes will check your bag at the entrance and prohibit non-compliant lotions.
Prepare your camera gear. If you plan on taking photos, bring a waterproof phone pouch with a lanyard. If using a GoPro, bring a floatable handle; if you drop it in a deep cenote, you will not be able to retrieve it.
Bring a quick-dry towel. A standard cotton towel will stay damp and heavy in your bag. Pack a microfiber travel towel that folds down to the size of a fist and dries in minutes.
