The Yucatan Peninsula has thousands of unique geological features called cenotes, water-filled holes or caves.The oldest cenotes are open to the air and the newest cenotes are completely enclosed underground.Cenotes were of great importance to the pre-Hispanic people that lived in this region, and the Mayans considered these places to be the entrance to the underworld.Many cenotes still contain artifacts that illustrate the importance of these locations to the Mayan culture.Several tour companies offer a wide variety of cenote tours throughout the region that will take you swimming, snorkelling, or diving in different cenotes with unique features.
