You’ll have a selection of Belizean and Guatemalan crafts to choose from when visiting any archaeological site, as vendors typically set up rows of stalls with similar gifts, crafts, textiles, and basketwork. You’ll also see slate carvings, a recently resurrected skill of the Maya.
Among the leading slate carvers are the Garcia Sisters, Lesley Glaspie, and the Magana family. Their work can be found in several Cayo shops as well as elsewhere in the country (especially Aurora’s shop near the entrance to Cockscomb [1]). The Garcia sisters helped revive the slate craze, and their quality has always been high.
Mennonite furniture pieces like hardwood chairs and small tables, make possible to take-hame items. Orange Gifts (in Cayo and San Pedro) has the best selection of crafts for sale in the country.
