Paso Guillaumet
Guillaumet Pass

Itinerario detallado

In this technically complex expeditionary traverse, we have the chance of getting so close to the eastern face of Fitz Roy massif, that we can almost touch it. It is a physically demanding trekking which requires technical equipment use. Besides, there are great height differences to be climbed, exposure to crevasses on great Piedras blancas glacier and some sections of low difficulty rock climb.

Day 1:
El Chaltén – piedra del fraile – Piedra negra high camp

Day 2:
Piedra negra – paso Guillaumet – Paso Superior

Day 3:
Paso Superior – laguna de los 3 – El Chaltén

It is vital for each participant to check all his/her equipment properly before traveling. Said equipment must be in good conditions, it must be comfortable and of course, it must be apt for the purpose. If at half the traverse, any element of the equipment fails, we will not be able to go on normally or of course replace it.
As for clothes, we always recommend synthetic ones, especially for the inner ones and the torso ones: if you wear sweated cotton t-shirt, you will suffer cold very much until our body helps it dry.
