The Jade Cavern (or Cenote Chempita) in Cozumel is a popular, natural sinkhole offering an adventurous and culturally rich experience. Swim in the Cenote: The primary activity is swimming or floating in the cool, refreshing, jade-colored freshwater of the underground cavern, offering a stark contrast to the tropical heat. Cliff Jumping: For the adventurous, there is a platform (typically 8–20 feet high) available for those who wish to jump into the deep waters of the cenote. Explore the Cavern: Visitors can admire the natural geological features, including impressive stalactites and other ancient rock formations created by centuries of mineral deposition. Mayan Significance: Cenotes like the Jade Cavern held immense spiritual importance for the ancient Maya. They were considered sacred wells and the only reliable source of fresh water on the peninsula. The Maya viewed them as portals to the Underworld (Xibalbá), and they were often sites for rituals, ceremonies, and offerings.
