Corbett · Central Highlands
Carn Dearg
Càrn Dearg is the 834m Corbett rising west of Loch Ossian, sharing the Corrour station catchment with Leum Uilleim and the lower Munros to the south. Train access from Glasgow to Corrour makes the hill among the genuinely car-free Corbetts, although the walk-in from the station is long and runs through some of the wettest country in Britain. The summit is reached over rolling grass-and-heather flanks; the views look east across Loch Ossian to Ben Alder and west to the Mamores.
Gaelic: “cairn-topped hill, red” · Pronunciation: karn jerr-ak

From Corrour railway station, follow the path south along Loch Ossian for around 4km. Where the path branches near Corrour Lodge, head south-west onto the open hillside and climb the broad east ridge of Càrn Dearg. A consistent climb up moor and grass leads to the small summit cairn. Return reverses the line to the station — pace it carefully to catch the train back. Allow 6–7 hours from station to station.
Terrain
Estate path along Loch Ossian for the first part — easy walking through one of Scotland's largest privately-owned native pine plantings. Above the path the ground is heather and bog with no real trail. The high point opens onto wide grass with an unremarkable cairn. Drier on the upper hill than the loch-side approach suggests.
In winter
Corrour station stays open year-round; the West Highland Line train is reliable in winter, making this a useful access option when roads close. Snow lies long on the broad summit and Loch Ossian itself sometimes freezes. The path runs through Forestry land that holds drift; navigation in cloud needs care above the loch.
This hill is in the Creag Meagaidh SAIS forecast area. Check SAIS forecasts in winter (December–April).
