Creag Mhòr reaches a height of 1047 metres (3435 ft) and qualifies as a Munro and a Marilyn. It is commonly climbed with the neighbouring Munro of Beinn Heasgarnich, which stands 3.5 km to the NE, the two mountains form the high ground between Glen Lochay and Loch Lyon. Creag Mhòr is one of the remotest of the southern highlands being situated about eight kilometres from the nearest public road, it is surrounded by other high ground which make it difficult to get a good view of the mountain from any valley, and the best aspect is obtained from the surrounding peaks. The mountains name translates from the Gaelic as Big Rock, an unusual name for a hill which is mostly grassy, however its top has craggy areas and the name refers to a series of rocky buttresses near the summit.
