Caana, or Sky Temple, at Caracol archaeological site in western Belize, is one of the largest, most impressive pyramids in the Maya world. Even more than a thousand years after it was built, Caana remains the tallest manmade structure in all of Belize. Caracol is located at the end of a long, red-clay road near the Guatemalan border. On December 21, 2012, the Belize Institute of Archaeology issued special camping permits and off-hours access to travelers. The reason? 13 b’aktun: the completion of the Maya Long Count calendar.
