After the heat of Chichén Itzá and the long walk between the pyramids, our next stop was a breathtaking cenote. We had a two-hour, refreshing swim in this fantastic place, one of the most unique natural features of the Yucatán Peninsula. Floating in the crystal clear, cool water between the limestone walls was exactly the refreshment we needed after the tropical sun.
Cenotes began to form millions of years ago, when the Yucatán Peninsula was still a coral reef lying below the ocean surface. During the ice ages, the sea level dropped, leaving the area dry, and rainwater seeped through the soft, porous limestone layers. This slightly acidic water carved out vast underground cave systems and rivers in the rock over the millennia. When the roof of one of these caves collapsed under its own weight, it opened the way from the surface to the underground freshwater reservoirs, creating the sinkholes we know today.
Cenotes were essential to the life of the Mayan civilization, as there are no surface rivers or lakes on the peninsula, so they were the only sources of drinking water. Cities, such as Chichén Itzá, were strategically built around these sinkholes. In addition to their practical use, they also had deep religious significance. The Mayans considered cenotes to be gateways to Xibalba, the underworld, where the rain god Chaac resided. In many places, ritual sacrifices and valuable objects were thrown into the depths to gain the gods’ favor.
Today, cenotes are ecological and tourist treasures of the region. Not only are they a paradise for divers and bathers, they continue to be the peninsula’s primary source of freshwater, and must be strictly protected from pollution. In modern Yucatán, cenotes have become symbols of conservation and sustainable tourism, combining the mystique of the past with the recreational needs of the present.
Cenote Chichikan, a spectacular open-type sinkhole, was particularly memorable. This site is also special because an entire Mayan cultural village has been built around it, where visitors can get a glimpse of ancient customs before descending into the depths. Chichikan’s water is incredibly clear, and the lush green vines hanging from its walls and the beams of light shining from above create a magical atmosphere, as if you were swimming in a natural cathedral in the middle of the jungle.
