Do I need a wetsuit in cenotes?

Not required but recommended. Cenote water is 72-78°F year-round, which feels cold after 30+ minutes of swimming. A 2-3mm wetsuit keeps you comfortable for longer sessions.

Can I wear regular sunscreen in cenotes?

No. Only reef-safe mineral sunscreen is allowed. Chemical sunscreens with oxybenzone or octinoxate damage cenote ecosystems. Most cenotes will turn you away if you have chemical sunscreen on.

What if I forget water shoes?

Some cenotes rent basic water shoes for $5-10, but selection is limited. The limestone floors are genuinely sharp and slippery - going barefoot risks cuts and falls.

How waterproof does my bag need to be?

Get an IPX7 rated dry bag that can handle full submersion. You'll likely splash it while swimming, and some cenotes require swimming to access different areas.

What to Bring for Cenote Swimming

Pack a wetsuit or rash guard, water shoes with good grip, waterproof bag for valuables, and reef-safe sunscreen. Most cenotes are 72-78°F year-round and have rocky limestone bottoms that can be slippery.

Choose your water protection. Bring a 2-3mm wetsuit for warmth and protection, or at minimum a long-sleeve rash guard. Cenote water stays cool (72-78°F) and limestone walls can scrape skin. Full wetsuits are worth it for longer swimming sessions.
Get proper footwear. Pack water shoes with thick soles and good grip. Cenote floors are rocky limestone with algae that makes surfaces extremely slippery. Avoid flip-flops or going barefoot.
Protect your valuables. Bring a waterproof dry bag for phone, keys, and cash. Many cenotes don't have secure changing rooms. A floating dry bag lets you keep essentials with you while swimming.
Pack reef-safe sunscreen. Use only mineral sunscreen (zinc oxide or titanium dioxide). Chemical sunscreens damage cenote ecosystems. Apply 30 minutes before swimming as it washes off easily in freshwater.
Bring a towel and change of clothes. Pack a quick-dry towel and dry clothes for after swimming. Most cenotes have basic changing areas but no towel rental. You'll want dry clothes for the ride back.
