White Coomb

The highest of the Moffat Hills, sitting above the Grey Mare's Tail waterfall and the hanging corrie holding Loch Skeen. A brilliant winter outing on a list usually thought of as gentle, with steep cornice-prone edges in cold weather.

Path from the NTS Grey Mare's Tail car park, climbing past the waterfall to Loch Skeen, then up the steep grass slopes to the summit dome.

Terrain

Good path to the loch. Steep grassy ascent above. Pathless on the summit plateau.

In winter

Gets full winter conditions in cold spells. Cornices form on the lee edges.

Outside the SAIS network. No Scottish Avalanche Information Service forecast covers White Coomb. 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 Southern Uplands for mountain weather, judge snow stability from first principles, and treat any cornice or wind-loaded slope with extra caution.
