Permit application to the Ejercito de Chile (for time period of Nov. 30th to December 25th and for the peaks of Tupunagato, Nevado de los Piuquenes and Cerro Alto - change accordingly to your dates and goal(s))
Before voting this one down (and causing it to disappear) because it does not show a nice mountain reconsider - this picture is posted in combination with permit infos for Tupungato and for people who want to do Tupungato self-organized, and speak not too well Castellano/Spanish.
This is a mountain information side. This is relevant info that can save you hassle.
