Cerro Aconcagua (6,960m/22,837ft) is the highest mountain in South America and is one of the "Seven Summits". It is located in the Andes mountain range, in the province of Mendoza, Argentina. The summit is located about 15 kilometres from the international border with Chile.
Having been already twice to Cerro Aconcagua, in my opinion the climb is not very technical. That of course is depending on which route you choose. I have approached the mountain in February 2012 via Punta de Vacas and in November-December 2013 via Horcones.
In 2012, I was quite ill a couple of weeks before the expedition started. I had hoped before departing for Argentina that I was in good health again. Unfortunately that was not the case. As I got higher on the mountain, my Bronchitis flared up again and I had to come down from High Camp. That was the end of the expedition.
In 2013, everything was going as planned. As we reached High Camp the winds became too extreme for proceeding safely. We were forced to return back down to Base Camp. The high winds unfortunately did not weaken and that was the end of the expedition.
I am looking forward to "Round Three" on Cerro Aconcagua in the future.
