Lake Atitlán was breathtakingly beautiful. And I don't say that lightly. The water was the bluest of blues and the skyline around the volcanoes was gorgeous. I took a tour from Panajachel, Guatemala (about 2 hours from Antigua) to villages surrounding Lake Atitlán, including San Juan, San Pedro and Santiago. The lake is the deepest in Central America and one of Guatemala's top tourist destinations. Lake Atitlán is definitely a must-see when in Guatemala.
