Glas-bheinn Mhor

Glas-bheinn Mhor (651m) — the big grey hill — sits south of Strathconon in the NH43 square between the River Meig and Loch Luichart. The flat rocky summit looks east toward the Affric watershed and north back across Strathconon to Beinn Mheadhoin and An Sidhean.

Gaelic: “grey-green, big” · Pronunciation: glass bheinn vore

Start from the small lay-by at Strathconon Lodge. Cross the bridge over the Meig and follow the estate track south-east, then strike up the broad north spur on rough grass and bog. The angle eases on the upper plateau; aim for the highest of the scattered rock outcrops to reach the cairnless top.

Terrain

Hard estate track then trackless grass and peat on the north spur. The summit plateau is a flat tableland of grass and lichen-spotted rock — a compass bearing helps confirm the high point.

In winter

The Strathconon hills hold modest snowpack but the plateau plays tricks in flat light when wind crusts the ground. Glas-bheinn Mhor's open top picks up easterly drift from the Affric divide; spikes are usually enough but the lack of features makes navigation the chief concern.

Outside the SAIS network. No Scottish Avalanche Information Service forecast covers Glas-bheinn Mhor. SAIS forecasts six areas only — Northern and Southern Cairngorms, Creag Meagaidh, Lochaber, Glencoe and Torridon — and this hill is outside all of them, so there is no avalanche forecast to read for it. In winter, use MWIS West Highlands ↗ for mountain weather, judge snow stability from first principles, and treat any cornice or wind-loaded slope with extra caution.

Before you go

Hillwalking carries real risk and the responsibility for any day on the hill is yours. Conditions in Scotland change fast and can differ sharply from the forecast — check the weather and the ground before you commit, turn back when the day stops working, and carry map and compass with the ability to use them rather than relying on a phone.

The distance, ascent and time shown on this page are editorial estimates for the usual line, not measurements from a recorded track — that is what the ~ means. Treat them as a rough shape of the day. Your own pace, the conditions and the exact line you take will all move them.

Mountain forecasts: MWIS and the Met Office mountain forecast. Access rights and responsibilities are set out in the Scottish Outdoor Access Code.

We check what we publish, but we cannot check the route on the day you walk it. Nothing here is a substitute for your own judgement.
