Glas Bheinn Mhor
Glas Bheinn Mhòr (997m) — "big grey-green hill" — is the central Munro of the upper Glen Etive cluster, sitting between Ben Starav to the west and Stob Coir' an Albannaich to the north-east. The hill has a distinctive shapely pointed summit visible from the head of Loch Etive and forms one of the key tops on the classic Glen Etive four-Munro round. Almost always combined with Ben Starav and often Stob Coir' an Albannaich on a long horseshoe.
Gaelic: “grey-green, big” · Pronunciation: glass bheinn vore

See Ben Starav for the standard pair route from the Etive footbridge at Coileitir. After Ben Starav, descend the east ridge to the deep bealach, then climb directly onto Glas Bheinn Mhòr — about a kilometre of sustained climbing on grass and broken rock. From the summit, push east to Stob Coir' an Albannaich for a longer round, or drop south-east into Coire Chaorach to return to Glen Etive. The Starav + Glas Bheinn Mhòr pair runs roughly 13km with 1300m of climb.
Terrain
The connecting ridge between Ben Starav and Glas Bheinn Mhòr is narrow turf and broken rock with one short rocky step. Glas Bheinn Mhòr's summit cone is a tight, pointed top with very little flat space. The drop south-east to Coire Chaorach for descent is steep grass — slippery in the wet. The north-east ridge towards Stob Coir' an Albannaich is broad and easy.
In winter
A serious Glen Etive winter day, often done alongside Ben Starav. The summit cone develops continuous cornicing depending on wind direction. East-facing slopes load with wind-blown snow under westerly weather. Glen Etive's narrow single-track road can drift closed and there is no mobile reception anywhere along the glen. Consult SAIS Glencoe for avalanche guidance.
This hill is in the Glen Coe SAIS forecast area. Check SAIS forecasts in winter (December–April).
