This area completely off-the-beaten-track will surely fulfill the most demanding trekker regarding encounters (miners, Indian healers, etc…) and Andean open spaces. This region located between 4000 and 5000 meters above sea level, is difficult to access and as a consequence little visited. The way is bordered on the West side by eternal glaciers and on the East side by deep valleys leading directly to the Amazon. The delight of the scenic beauty and the particular atmosphere of the kallawayas lands (frenetic gold rush, Indian medicine) will largely outweigh the trouble of your efforts. Bellow the hillsides on which we progress, the Amazon stretches as far as the eye can see. We only have to loose a little elevation and we enter in pour Madidi Park, starting here and finishing a lot lower, near Rurrenabaque. It is said that they are the last direct descendants of the Tiwanaku lords whose language they still speak is the Pukina. They are also, and above all, the last knowledge holders of the powerful plants of the Altiplano. Principal summits: Chaupi Orkho: el. 6 040 m.a.s.l.
