Packing for Cenote Swimming and Cave Diving in Mexico
Prioritize high-quality, reef-safe gear and specialized equipment that handles freshwater acidity. Focus on redundant lighting, exposure protection for cool water, and reliable dry storage to protect your electronics from high humidity.
- Select the right exposure suit. Cenotes maintain a constant temperature around 75°F (24°C). Bring a 3mm wetsuit for extended swims or dives. If you are diving, ensure it has minimal branding to avoid damaging delicate limestone formations.
- Upgrade your lighting. Cenote interiors are pitch black. If you are diving, carry one primary light (min 2000 lumens) and two backup lights. For swimming/snorkeling, bring a waterproof headlamp if you plan to visit semi-open cenotes with deep caverns.
- Pack reef-safe protection. Many cenotes strictly prohibit standard sunscreen because it contaminates the water table. Pack biodegradable, mineral-based sunscreen (zinc oxide or titanium dioxide only) or, better yet, a UV-protective long-sleeve rash guard to avoid lotions entirely.
- Organize your electronics. The humidity in the Yucatán is extreme. Bring 2-3 large silicone desiccant packs and a high-quality 20L dry bag to keep your camera and phone away from water and damp air.
- Do I need to bring my own snorkel gear?
- You can rent it at almost every cenote for $5-$10, but your own mask will provide a better fit and clearer vision.
- Is a GoPro necessary?
- It is worth it, but make sure you bring a red filter if you are diving deeper than 10 feet to correct for the color loss in the dark water.
- Can I wear bug spray?
- Most cenotes forbid bug spray for the same reason they forbid sunscreen. Apply it only after you leave the cenote area.
