At 6959m Aconcagua is the highest peak in the Andes. It is also the highest in the world outside of central Asia. It was also one of the first major peaks in the Andes to be climbed - the first ascent was in 1897 by Zurbriggen and Vines.

Today Aconcagua is one of the busiest peaks in the Andes, with thousands of climbers coming every year to attempt the normal route. Although not technically difficult the normal route is still a demanding ascent, both physically and mentally. it may be the highest peak in the world you can walk up, but only if you have done a lot of walking and are very experienced. The Polish glacier provides a more interseting and scenic route to the summit, though it is by no means very difficult.
