Laguna Diablo and Cagliero glacier

On the edge of this lagoon, and with an almost surreal presence in this remote area, is the mountain refuge Puesto Cagliero. This retreat allows you overnight stays in its comfortable facilities enjoying the unbeatable views of the glacier and the lagoon next to the warm heat of the fireplace.
