Cuello is a Maya archaeological site about 5 kilometres west of Orange Walk Town on private agricultural land. Unlike Lamanai's dramatic jungle setting, Cuello is modest in appearance — the visible structures are low mounds among sugarcane fields — but its archaeological importance is exceptional. The site has produced evidence of Maya settlement dating to around 2500 BC, making it one of the earliest known Maya communities in Belize.
Visiting requires arranging access through the rum distillery that owns the land (Cuello Bros, Orange Walk's local distillery). The combination of archaeological site and working rum operation makes for an unusual excursion, and the distillery tour is worth including. The site itself rewards visitors with an interest in Maya prehistory more than those looking for photogenic pyramids — bring the context you've gathered from the Banquitas House of Culture.
