This dive site, Cenote Chan Hol, is an intriguing submerged cave system located in Quintana Roo, Mexico, forming part of the larger Toh ha cave system. It holds significant paleoanthropological interest due to the discovery of three prehistoric human fossils within its depths. Divers navigate through its unique underwater geology, often following guideline ropes, exploring a labyrinth of passages that reveal ancient formations and a window into prehistory.
The cool, clear waters of Cenote Chan Hol host a specialized ecosystem. While large marine life is absent, divers can encounter intriguing smaller creatures such as shrimps and fascinating blind cave fish, identified as a type of bream, perfectly adapted to the perpetual darkness of the inner cave environment. Photosynthetic plants can be observed in sections where natural light penetrates.
Cenote Chan Hol is suitable for diving year-round, with stable water temperatures typical of cenotes. It offers excellent visibility, making it a prime location for wide-angle and macro photography. While the shallow average depth of 5 meters makes it accessible, the overhead environment of the cave system means it is best explored by divers with cavern or cave training, or under the guidance of experienced cenote dive masters. Freedivers and snorkelers can enjoy the open water and shallower, well-lit sections.
