Volcano, 3776 mts. South face. Technical climbing (AD, ice: IV). From San Martin de los Andes (100 Km) / Junin de los Andes (60 Km) to Huechulafquen
lake (Paimun area). It is possible go by car/bus till the ranger office (900 mts. over the sea level). What I usually do is from
there hike till 2600/2700 mts. in the first day, it takes ~6 hours (years ago was a small vivac, however nowadays is not 'cause
an avalanche and it is necessary to carry a tent or similar). Second day, with crampons to 2850 Mts. where the "colada" is
(quite small ice-passage between two enormous exposed rock walls), after that ice/snow climbing till 3400 Mts., time depend
on ice conditions, which are very changeable so it is necessary to look for the best way on the moment: "vamos viendo" is our
most used Spanish expression. From there is just a hike to the summit (be care on the last 150 mts. 'cause of crevasses).
Descent is by the same route or by the north face.
