    Help Protect the Environment

    Cenotes are part of a delicate ecosystem. To preserve its crystal-clear waters and the life within:

    • Only use biodegradable sunscreen, as regular ones can contaminate the water and harm aquatic life.
    • Shower before entering to rinse off any lotions, oils, or insect repellents.
    • Never touch or remove stalactites, stalagmites, or any rock formations—these natural structures take thousands of years to form and are protected by law. Removing them is illegal and considered an environmental crime.
    • Take all your trash with you and help keep the area clean.
    • Stay on marked paths to avoid damaging the surrounding jungle or underground cave systems.
    • Avoid loud music or shouting, as it disturbs the wildlife and the tranquil experience of other visitors.

    Do not feed animals or leave food behind, as this disrupts their natural behavior and attracts invasive species.

    Your respect helps keep this natural wonder pristine for future visitors.
