Corbett · Glen Etive
Glas Bheinn
This Glas Bheinn — "green hill", a common Highland name — is the 789m Corbett on the eastern fringe of the Black Mount, in the rough country between Glen Etive and Loch Tulla. The hill is overshadowed by its Munro neighbours in the Black Mount but offers a quieter alternative with one of the most striking views of the Stob Ghabhar massif. The summit is a small cairn on a grassy dome with steep crag-broken flanks dropping into Glen Etive on its west side.
Gaelic: “grey-green” · Pronunciation: glass bheinn

Standard route
estate road 30% · rough heather 30% · grassy ridge 30% · summit dome 10%
The most direct approach starts from Forest Lodge at the head of Loch Tulla on the A82 and follows the estate road west toward Clashgour. About 3km along the road, step off and climb pathless heather and grass to gain the broad south ridge of Glas Bheinn. A steady plod up the ridge reaches the cairn. About 14km return with 647m of climbing. Sometimes combined with Beinn Mhic Mhonaidh or extended toward Stob Ghabhar for a major day.
Terrain
The Clashgour estate road is firm gravel. Above the track the lower hill is rough heather and peat; the upper ridge is short grass with intermittent crag bands. The summit dome is broad mossy grass. The west face is steep and crag-broken — keep east of the summit cairn on descent. No exposure on the standard line.
In winter
A reasonably serious winter hill — the west face becomes a serious snow slope after westerly storms, and the summit ridge can hold cornices on the west edge. The A82 corridor is gritted but the lay-by ices. Forest Lodge accessibility is reliable in any conditions. Best done as a clear-weather day.
This hill is in the Glen Coe SAIS forecast area. Check SAIS forecasts in winter (December–April).
