Welcome. And would you like to tell me something more about the place from where you come from. It seems interesting.
Guatemala is located in Central America, its official language is Spanish (23 indigenous languages have been officially recognised, but all transactions are in Spanish). Some nice touristic places are: Antigua,Tikal, and Lago de Atitlán. More info. at Wikipedia.
