The ascent combines the evergreen forest and the vestiges of the last eruptions, combining trekking in the forest and volcanic scree with easy climbs on rocks during the summer or on snow during the winter and spring. In its upper part, there is a large crater on the east side and a rock pyramid on its main summit (southwest).
Rising almost 1,500 meters above the surrounding peaks, with a truncated shape as a result of a violent eruption in 1893 and presenting significant volcanic activity in 2015 and 1961. The Calbuco receives its name from the first peoples who traveled through these lands and although Kallfüko is not its only denomination, it is the one that has transcended and speaks of the mountain of blue waters where the evergreen forest, “coihues”, “ulmos”, tepa and of course the “murtas” predominate. And where foxes, pudúes, pumas, and a great variety of birds inhabit, from the “chucao” in the deepest of its forests to condors in the ravines and rocks of its upper part.
Its climb is a long day that runs along its south face, in the Llanquihue National Reserve, and that will demand a long approach through an evergreen forest that treasures in its interior several “Alerce” trees. Following the course of the Blanco River, we will first try to reach the place where a rustic shelter used to be located. Once in this place, we will replenish our energy with the views that we will achieve by gaining altitude and continuing the ascent in a rockier terrain, with rocky climbs to reach the base of the summit tower. In winter and spring, it is possible that this stretch is snowy or icy!
The return to the vehicle is long. Therefore, the maximum starting time will be 2 pm. With this, we will have a demanding day, with great views, lots of green and, we hope, a beautiful summit of the volcanoes of southern Chile!
