You can find the Guatemalan jumping pitviper in southern Mexico, specifically in southeastern Chiapas. It also lives in southern and central Guatemala, and western El Salvador. The first place this snake was officially found was near San Augustín in Guatemala. This area is on the southern side of a volcano called Volcán Atitlán.
