Aonach Mor is connected via a high bealach to its neighbour Aonach in a ridge that runs north to south. Aonach Mor would by its name translation "big ridge" be assumed to be the larger hill (in altitude) than Aonach Beag but it is actually smaller and the name refers to the bulk size of the hill which Aonach Mor is larger. The north slopes of Aonach Mor have been heavily developed for skiing and as such most walkers tend to keep away from here. The ski area also boats downhill mountain bike tracks which are used in the summer months and has been the host to the world championships. The Aonach Mor - Aonach Beag ridge is also connected via a low Col to Carn Mor Dearg to the west. Climbing from the south to this col is a common route to climb the two Aonachs.
From the summit there are superb views to be had of the entire grey corrie ridge to the east. You can really appreciate how vast and complex this particular ridge is from here. There are obviously also fantastic views North tot eh Munros in the great Glen. Since Aonach Mor is so high the views on a clear day can be uninterrupted for extremely large distances.
As mentioned most people climb Aonach Mor (and Aonach Beag) from the south in Glen Nevis. There is parking available at the western head of the Glen with a short walk in through the valley floor.
