The dominating mountains in the Chilean Lauca National Park are the two Payachatas (twins) Volcan Parinacota and Volcan Pomerape. The first one is with 6342 meters sea-level slightly higher and it is a perfect cone, one of the most beautiful mountains on earth. Both are covered with snow and ice. They are located on the border to Bolivia, there in the Sajama National Park .
On foot of the Payachatas are the picturesque villages Parinacota (Chile - West side) and Sajama (Bolivia - East side). The most popular and common ascent to Volcan Parinacota is from Sajama via the northern ridge, which arises from the saddle between the two volcanoes. It provides beautiful views to the southern glacial face of Volcan Pomerape and to Bolivia's highest mountain on the opposite side of the village: Majestic but icy Nevado Sajama (6542 meters sea-level).
Due to the high altitude of the village Sajama (more than 4200 meters) good acclimatization is mandatoty. On the Chilean side are some nice tours to gain it properly.
