Càrn Dearg (Corrour)

Càrn Dearg, at 941 metres, is a remote peak between Rannoch Moor and the Ben Alder range above Loch Ossian, almost always climbed together with neighbouring Sgòr Gaibhre from either of two possible railway stations.

The route starts from Corrour Station, following tracks around Loch Ossian past the lodge and through birch woodland before crossing open ground towards Càrn Dearg's slopes — an alternative approach from Rannoch Station follows a fine estate track past the ruins of Old Corrour Lodge, from where a faint trod climbs the north bank of a burn, aiming for breaks of grass among the heather-clad slopes, before delightful grassy ground leads to the summit's large, well-formed cairn.

From the summit, a faint, worn path heads east before turning north-east down Càrn Dearg's broad shoulder, becoming more obvious as it cuts through heather to the peaty, often soggy bealach of Màm Bàn. From here, easy progress continues on a path climbing gently up Sgòr Gaibhre's grassy western shoulder, passing impressive erratic boulders on the way to the second summit.

The combined round taking in both Munros can be approached from Corrour Station, from Rannoch Station via a longer horseshoe over the Corbett Beinn Pharlagain, or as a train-assisted point-to-point walk between the two stations — a popular and efficient option for those without transport concerns, walking from Corrour and returning to a car left near Rannoch, or vice versa.

The round trip is typically six to eight hours depending on route choice; several regular visitors caution that even seasoned hillwalkers have become disorientated on this remote, largely featureless terrain in poor visibility, with one detailed account describing a serious navigation error in low cloud.

There is no road access to Corrour; trains run from Fort William or Glasgow via the West Highland Line. Rannoch Station, with road access via the B846, offers an alternative starting point and is also served by the same rail line.
