Carn Liath is part of a 3 Munro group known the Creag Meagaidh group. Carn Liath is the most eastern Munro in the group and sits as a high point on a long ridge running from the summit of Stob Poite Coire Ardair in the west to the River Spey in the east. To the north there are easy slopes leading down to the Glenshirra Forest but south there are much craggier slopes particularly west of the summit where the back walls of Coire Ardair are a formidable sight. The summit is rounded in comparison to its more pointed neighbours.
From the summit there are fantastic views west of the complex Creag Meagaidh and the back headwall of coire Ardair.
As mentioned Carn Liath is normally climbed in a group of 3 Munros from south at the A86 where there is a large car park. Carn Liath itself is normally climbed from the west by the connecting ridge with Stob Poite Coire Ardair.
This is a superb walk and is widely regarded as one of Scotland's best hill walking expeditions.
