The Papallacta Hot Springs One of the most important natural resources of the complex is the thermal waters, which were already valued by the Incas. For them, Papallacta was a healing center and an obligatory step for tired or wounded warriors. Currently, the site is opening a space in international tourism. The phenomenon that occurs here is called boiler. In the old days, there was a very large volcano that lost its pressure and formed a magma chamber inside. Due to the pressure of the mountain, said chamber collapsed and created the derivations. The hot water coming from the crater runs through the existing cracks from the earth's crust to the magma. The contact of the water with the vapors causes the liquid to come out through the cracks
