The easy inclined broad slopes which go south west from the summit descends to the 795 metre col at the head of Butchart's corrie from here the neighbouring Munros of The Cairnwell and Càrn a' Gheòidh can be easily climbed. 200 metres west of the col is Loch Vrotachan, owned by the Ballater Angling club this offers good trout fishing at a height of 750 metres. The summit itself is made up of small light coloured quartzite rocks, giving the mountain a distinctive appearance. There are twin summit bumps with the western top having a height of 903 metres while the true top lies 400 metres to the east and is marked by a small pile of quartzite boulders. Càrn Aosda very much belongs to the eastern half of Scotland and all drainage goes via Glen Clunie and the River Dee to reach the east coast at Aberdeen.
