I climbed with Acomara which charges a good deal less than Aymara although they are the same company and merge the groups together so the people who pay more with Aymara get the same as those who have paid less with Acomara.
Although the ACOMARA AYMARA Aconcagua Expeditiones website is very very good DO NOT BE FOOLED as this is just to cover up how inexperienced their staff are. I recommend INKA. DO NOT USE AYMARA OR ACOMARA _ you WILL REGRET IT!!
This is an AWFUL COMPANY so do not climb with them.
They are extremely UNPROFESSIONAL and my personal safety was put at risk a number of times not to mention me being the only girl and one of the guides making various passes at me. I was made to feel very uncomfortable because I was English (something which I have never experienced before) as one of the guides kept referring to me as greedy British in reference to the Falklands initially but then started incorporating it at eating times so that I felt so uncomfortable I was not eating properly. They left me behind in a snowstorm on summit day. All in all im just glad to have gotten home alive and it has put me off trying again until I am a bit older as I am 24 now but I didnt feel strong enough in myself to stand up for myself as I should have.
USE 'AA' Adventure Alternative ' I climbed Kili with this Company in 2010 and they were faultless OR climb with INKA, I passed climbers climbing with INKA and they only had good things to say about their expedition and guides and equipment etc.
