Drive to the port in Belize City via a stop to check out the ATM Caves near San Ignacio. It’s a “hole in the wall” but anything but a cash dispenser! The cave system is a Mayan archaeological site, and contains ceramics, stoneware and, in the main chamber, human bones. This chamber was also discovered to be full of Mayan pottery.
Bones and skulls were revealed scattered amongst the pottery, some - very much intact - including an unbelievably well-preserved complete human skeleton.
If this isn't spooky enough, on your closely guided visit – in which you have to swim, climb rocks and spend hours in the dark - you'll see where the Mayans have manipulated cave formations to create the faces of men and animals, project shadows or serve as makeshift altars. Bats flit around and tropical fish inhabit the waters.
Drive to the port in Belize City. The boat trip by water taxi to Caye Caulker takes about 45 minutes, through turquoise waters and a maze of mangrove islands.
