Belize is home to the largest cave system in all of Central America. Visitors never cease to be amazed by the awe inspiring stalactites and stalagmites inside the caves, though the ancient Maya took a very different view of these magnificent structures. The Maya believed the caves or actuns as they were known, were a portal to Xibalba, the underworld, and used them for religious ceremonies. One should only explore caves with experienced tour guides that have expertise to guide you.
