Edit (12-12-17) : I have found a partner, but if you are willing to join, we're open!
I will be peak-bagging in Chile and Argentina from mid-January to late-February. Objectives are first Marmolejo and San José, then Ojos del Salado and Llullaillaco, then Mercedario and Aconcagua.
I chose non technical routes since I planned on going solo, but I am comfortable on alpine PD and basic glacier travel if we are a team.
Even if you don't want/need a partner to climb with, I will be more than happy to share some of the transportation costs if you are also heading for one of these mountains.
I am from Canada, and speak English, French, basic Spanish and basic Chinese.
Anyone has tips on renting a car in Copiapo to drive to Ojos del Salado, and hitchhiking from Barreal to Mercedario?
And which permit you have to get for Aconcagua if you go in by the Horcones valley and out by the Vacas valley?
