This Bolivian eco-region is one of the mostly appreciated places because of its biodiversity and impressive scenery. It extends through paths of amazing mountain peaks, canyons covered by woods and water falls. It is the point of encounter of two regions: the “Amazonía” and “el Chaco”. The spurs of the western chain of mountains that, lying almost rectilinear from south to North, briskly turn towards the northwest, towards Perú, find here a point of inflection. This excursion is one of the favorite one among nature lovers because of the possibility of seeing condors, a great variety of mammals and rodents.
