Sgurr na Ba Glaise
Sgùrr na Bà Glaise — 'peak of the grey cow' — is the highest summit of the Rois-bheinn group in Moidart, a 874m Corbett standing above Lochailort and the West Highland railway. The mountain forms the central peak of easily the finest small ridges in the western Highlands: a four-Corbett traverse linking Rois-bheinn, Sgùrr na Bà Glaise, An Stac and Beinn Mhic Cedidh in a long day from the coast road. The summit gives views west to the small islands of Eigg and Rum and east to the Glenfinnan Munros.

Park at the Inversilort parking area on the A861 between Lochailort and Glenuig (NM767812). Pass under the West Highland railway line and pick up a path heading up Coire a' Bhuiridh onto the broad east ridge of Sgùrr na Bà Glaise. The route climbs steadily to the summit cairn perched on a low rock outcrop. For the full Moidart traverse, continue west over An Stac and Rois-bheinn for a 9–10 hour day with significant re-ascent. Sgùrr na Bà Glaise alone is 6–7 hours.
Terrain
Lower slopes are heather and bracken — slow in summer growth. The middle section is grass with occasional rock outcrops. The summit ridge is firm rock and grass with mild exposure on the south side. The four-Corbett traverse involves several steep cols requiring careful footwork.
In winter
In winter the Rois-bheinn ridge becomes a serious mountaineering proposition — narrow connecting cols, exposed traverses, and tight daylight windows even on the shortest options. Sgùrr na Bà Glaise alone gives a manageable winter day with snow lying well on the east aspect. The A861 is usually clear of snow but the Glenuig road can be slow.
This hill is in the Glen Coe SAIS forecast area. Check SAIS forecasts in winter (December–April).
