The property begins on the southern slope of the Chillán Volcano. It limits to the north with the Nevados de Chillán skI center and to the south with the Ñuble National Reserve. In its highest part, thermal waters emerge with more than 200 liters per second flow and temperatures close to 140 °F. This source of waters makes up the Diguillín river that runs through the field for around 20 kilometers. The estate includes about 4,500 hectares of native forest where the presence of Coihue stands out, which gives its name to the property. There is also a variety of Oak, Raulí, and Cypress from the Andes Mountains.
Currently, the land is visited by hundreds of tourists each year for its high biological value, it's hot springs, and the virtues it presents for the development of adventure sports such as backcountry skiing, mountain biking, and trekking.
This place is very interesting in the biodiversity of the mountain range and this is how you can see wild fauna such as the condor, the black woodpecker, cachañas, chucao, pumas, foxes, wild boar, and some huemul among others.
All these hectares are totally virgin, without any construction, and it is currently declared a Biological Corridor, and World Biosphere Reserve by UNESCO, a great advantage for the development of any tourism project.
