Set in Guatemala's western highlands, Lake Atitlán fills a vast volcanic caldera. Its deep blue waters are framed by steep crater walls and the cone-shaped volcanoes Atitlán, Tolimán and San Pedro. Wooden piers stretch into the still lake, emphasising the contrast between its calm surface and the rugged terrain shaped by volcanic activity.
