Corbett · Argyll & Bute
Cnoc Coinnich
Cnoc Coinnich is the 763m Corbett standing between The Brack and Beinn an Lochain at the centre of the Arrochar Alps, above the Rest and Be Thankful. The name means 'mossy hill', a description that holds up after rain. The mountain is overshadowed by its better-known neighbours — The Cobbler, Beinn an Lochain, Beinn Narnain — but the summit gives one of the cleanest viewpoints of the Arrochar group at modest height and effort. Newly added to the Corbett list after a 2012 re-survey reclassified it from a Graham.

Park at the Ardgartan car park on the A83 (NN272039), where the Brack also starts. Take the forestry track east through Coilessan, then turn south up Coilessan Glen on a path that climbs steadily. From the bealach between Coilessan and Cnoc Coinnich, climb west onto the broad summit ridge. The cairn sits on a small rocky outcrop. Return reverses the line, or extend with The Brack from the same forestry start. Allow 5–6 hours.
Terrain
Forestry tracks and a rebuilt path cover the lower slopes — kept up by the Forest Park. Above the trees the going turns to heather, grass and small rock outcrops. The summit area is broad with a modest cairn perched on low rock. Notoriously boggy underfoot, even in dry weather — the name is accurate.
In winter
Maritime Arrochar winter — snow is intermittent and rarely deep, but the rocky upper section ices up readily. The Ardgartan road stays open year-round. Cold easterlies funnelling up Loch Long can be ferocious on the open ridge. Pair with The Brack for a Corbett double from the same forestry start.
