One of two major Guatemalan ports on the Gulf coast, Santo Tomás de Castilla is a few kilometers south of Puerto Barrios on Santo Tomás Bay. It is Guatemala’s largest and most efficient port on the Caribbean Ocean. It was formerly known as Matías de Galvez, and now handles 77% of the country's exports and half the imports, as well as 20% of El Salvador's imports and 10% of its exports. It is a wonderful place to get an authentic taste of local Guatemalan culture.
