Carn Dearg Mor
Carn Dearg Mor — "the big red hill" — sits in the empty country between Glen Feshie and the Geldie Burn, on the south-west flank of the great Cairngorm plateau. At 857m the rounded red-granite summit is a Corbett in stature though surrounded by Munros; its 290m of re-ascent off the high plateau is what earns it the classification. The view east takes in the full sweep of Cairn Toul, Braeriach and Carn an Fhidhleir — a properly arctic Cairngorm panorama with no road in sight.
Gaelic: “cairn-topped hill, red, big” · Pronunciation: karn jerr-ak more

The shortest line is from Achlean in Glen Feshie, taking the public footpath south through the pinewoods then climbing east up open heather and granite gravel to the summit dome. A longer alternative starts from Linn of Dee via the Geldie path. Both involve about 15km return with 754m of ascent. Many baggers pair this hill with Mullach Clach a' Bhlair or An Sgarsoch for a long, committing south Cairngorm day.
Terrain
The Glen Feshie path is firm and well drained through the pinewoods. Above the trees the ground turns to red granite gravel and short heather — easy walking with little path. The summit dome is featureless with the cairn on a small platform of broken granite. No exposure or scrambling anywhere on the hill, but the open ground gives no shelter once above the trees.
In winter
A bleak winter day on the open south-Cairngorm fringe — full plateau wind exposure but with gentle gradients and no significant avalanche slopes. The Glen Feshie pinewoods give shelter on the approach. Drifting fills the upper slopes; navigation in whiteout is the chief skill. Access roads to Achlean or Linn of Dee can be slow after heavy snow.
This hill is in the Northern Cairngorms SAIS forecast area. Check SAIS forecasts in winter (December–April).
