There are two theories about Cajas name’s origin. The first theory. Cajas is an original word from the Quichua language: Caxas and its meaning is: cold. The second theory considered comes from the appearance, geological formation and height of its mountains that visually form boxes that surround the lagoons in its interior. The Cajas National Park is impressive for its beauty and its vast extension of 28,544 hectares. At times the national park seems to find no limits in nature. Mountain after mountain, peak after peak caresses the sky with its different morphologies, as the altitude range in the national park goes from 3,152 (10341 feet) metres above sea level to 4,445 (14583 feet) above sea level.
