Guatemala's largest lake, Lago Izabal, is located in an isolated, stunningly beautiful, forested section of the country, which is largely ignored by tourists. The river port town of Fronteras, commonly called Río Dulce, is the only major settlement in the area, and is located at the narrow section where Lago Izabal becomes the Río Dulce, which flows northeast toward Livingston and the sea.
