William and Kate left Belize after a four-day visit in which they enjoyed the nation’s heritage, Mayan culture and dancing with the locals.

Their next stop is expected to be in Jamaica as part of their Caribbean tour, where they will then visit Trench Town, the Kingston neighborhood where reggae artist Bob Marley grew up.
