THE UNEXPLORED WILDERNESS OF THE MAYAN UNDERWORLD

In a region with few or no rivers, the cenotes –sinkholes containing underground water that are typically found in karstic terrain—are a vital source of freshwater. In some areas of the Yucatan peninsula, cenotes are connected by extensive underwater cave systems, —most of them unexplored— that expand over hundreds of miles, conforming one of the largest underground wilderness on earth. Cave diving is possible in many of them, specially in the Caribbean area, as is the case of Dos Ojos, near Tulum while others can be visited only at the surface such as Dzibilchaltun or the Sacred cenote of Chichen Itzá.
