Cenote Swimming: A Practical Guide to Safety and Savings
To swim in cenotes safely, always rinse off sunscreen before entering and wear a life vest if you are not a strong swimmer. Save money by renting a bicycle or taking 'colectivos' (shared vans) instead of booking guided taxi tours.
- Select your cenote based on type. Open-air cenotes look like swimming holes and are easier for beginners. Cave or semi-open cenotes require navigating stairs and darker water; visit these only if you are comfortable in enclosed, deep-water spaces.
- Use biodegradable products only. Sunscreen and insect repellent contain chemicals that kill the cenote ecosystem. Shower thoroughly at the entrance to remove all lotions, oils, and perfumes before entering the water.
- Rent gear locally. Don't bring your own snorkel gear if you are flying light. Most cenotes rent masks and life vests for $3–$5. Bringing your own towel and water shoes is the best way to avoid 'convenience' fees.
- Prioritize transportation. Avoid private taxis. Use the local colectivo vans running along the main highway (e.g., Highway 307 in the Riviera Maya). They cost roughly $2–$4 per ride compared to $30+ for a taxi.
- Do I really need a life vest?
- Yes. Cenote water is fresh, not salt water, meaning you are less buoyant. Many cenotes are 10–30 meters deep; even strong swimmers get fatigued.
- Can I drink the water?
- No. The water is groundwater and can contain bacteria. Do not swallow it while swimming.
- Is it safe to go alone?
- Yes, if you stick to popular, managed cenotes. Avoid swimming in remote, unmanaged cenotes if you are alone, as there is no one to assist if you slip or have trouble.
