The Museo de la Cultura Maya, on Avenida Héroes near the corner of Mahatma Gandhi, is the standout sight in Chetumal and a useful warm-up before any trip to the Maya ruins of southern Quintana Roo or Belize. The exhibition is organised around the three levels of the Maya universe — underworld, earth, sky — using a central ceiba-tree sculpture that runs through the building.
Displays are bilingual and emphasise concepts rather than relics: how the Maya counted and wrote, how the calendar worked, how astronomy informed religion and farming. Interactive tablets let you write your name in glyphs and run through Maya mathematics. Open Tuesday to Sunday, around US$4 entry. Allow two hours.
