Calcehtok Caves

The Calcehtok caves are said by some to comprise the longest dry-cave system on the Yucatán Peninsula. More than 4km have been explored so far, and two of the caves’ 25 vaults exceed 100m in diameter (one has a 30m-high ‘cupola’). The caves hold abundant and impressive natural formations, human and animal remains and plenty of artifacts, including many haltunes (stone basins carved by the Maya to catch water). Archaeologists have found and removed ceramic arrowheads, quartz hammers and other tools, and you can still see low fortifications built by the Maya who sheltered here during the War of the Castes.
