Parinacota is a stratovolcano with a height of 6,348 m on the border between Chile and Bolivia in the Atacama Desert area. It is located in the Lauca National Park, 145 kilometers east of Arica in the Cordillera Occidental of the central Andes. Together with the neighboring Pomerape volcano, which lies northeast of it, it forms the Payachata complex. At its feet lies Lake Chungará. His current activity is limited to fumarole activity. More general information can be found on Wikipedia.
The normal route from the Bolivian side starts between the two volcanoes Parinacota and Pomerape and can only be reached with off-road vehicles. The climb goes quite directly towards the summit, although the path is usually not visible because it is covered by snow or snow. However, that's not a problem, you just go straight up until you reach the highest point. You won't be confronted with any major technical difficulties, but the climb will take longer due to the high altitude and the quite a few meters in altitude that have to be covered. Acclimatization in advance is definitely recommended. Breaking into the frozen snow cover on the surface also doesn't make the climb any easier.
However, the gigantic view of the enormous crater, of the Parinacota and the Sajama, as well as the Altiplano, Acotango and much more, rewards all the effort.
