Beinn a Chlachair lies on its own separate from any connecting Munros. For this reason it is normally climbed on its own but it can be combined with Creag Pitridh and Geal Charn to the north if you are fit. It is a fantastic looking Munro that is well seen from the north in Glen Spean.
The Munro lies at the SW end of a small ridge running SW to NE. There are very steep crags on all of its SE slopes. To the NE of the summit the ridge is bitten into by Coire Mor a' Chlachair which again gives sharp drops to the corrie floor.
The hill can be ascended from either the SW ridge or NE ridge as each have good stalker paths leading to the summit. The NE ridge is probably most popular due to easier access from the A86 road.
From the summit there are good views to be had of the Munros NW of Ben Alder.
Access is normally from the north at Moy Bridge just next to the Laggan Dam. It is a fairly long walk in but no where near as remote as the Alder group to the south.
