Located about 16 Miles from San Ignacio you find probably the largest collection of Maya pottery in the world. Che Chem ha (Cave of the Poisonwood water) is about 800 ft long was used by the Maya for many centuries for food storage and rituals. The cave is not as spectacular in terms of its formations of stalactites and stalagmites like others in the country but pottery shards litter the entire floor and in some corners you find complete but small pieces: and if you look closely you can see details on the relics.
