Lake Atitlán (Lago de Atitlán) is a large endorheic lake (one that does not flow to the sea) in the Guatemalan Highlands. While Atitlan is recognized to be the deepest lake in Central America, its bottom has not been completely sounded. Estimates of its maximum depth range up to 340 meters. The lake is shaped by deep escarpments which surround it and by three volcanos  on its southern flank. Lake Atitlan is further characterized by towns and villages of the Maya people. Lake Atitlán is about 50 kilometres (31 mi) west-northwest of Antigua. (text from Wikipedia)
