Chno Dearg
Chno Dearg (1046m) — "red nut" — is the higher of the two Munros above the deep glacial trench of Loch Treig, paired with Stob Coire Sgriodain to the south-west. It is a broad whaleback summit looking out over the West Highland Line as it runs along the shore of Loch Treig to Corrour. Best climbed as a horseshoe of both Munros from the small hamlet of Fersit, which sits at the head of the loch and the start of the rough track south.
Gaelic: “red” · Pronunciation: chno jerr-ak

Park at Fersit at the end of the side road off the A86 west of Tulloch. Cross the railway via the level crossing and climb the broad north-west ridge of Stob Coire Sgriodain, with views straight down the length of Loch Treig. From Sgriodain drop east-south-east to the col and climb directly onto Chno Dearg via its broad west shoulder. Return north over Meall Garbh and down to Fersit. Around 14km with 1100m of ascent for the pair; Chno Dearg alone is 11km with 850m up.
Terrain
The Fersit approach crosses the railway line — be alert, this is the working West Highland Line. Above the crossing the ground is wet boggy moor with no clear path; pick a line up to the broad north-west ridge of Sgriodain. Higher up the ridges turn to short grass and gravel, easy walking. The bealach between Sgriodain and Chno Dearg is broad and wet. The summit area of Chno Dearg is a large flat top with the cairn marking the modest high point.
In winter
A relatively benign winter Munro pair, but the open whaleback summits are fully exposed to westerly weather coming off Rannoch Moor. The east face of Chno Dearg above Coire an Easain Bhig holds wind-loaded snow. The A86 to Fersit is gritted but the Fersit side road can drift closed. Phone signal is intermittent. SAIS Creag Meagaidh applies to the western corries.
This hill is in the Creag Meagaidh SAIS forecast area. Check SAIS forecasts in winter (December–April).
