Corbett · Central Highlands
Beinn Iaruinn
Beinn Iaruinn — 'the iron hill' — is the broad-shouldered Corbett rising above the Parallel Roads of Glen Roy, the famous Quaternary shorelines that puzzled geologists for a century before being recognised as ice-dammed loch terraces. The 804m summit sits above the parallel roads themselves and gives a unique vantage on the geological feature visible right below. Beyond Glen Roy, the view sweeps west to Ben Nevis and the Aonachs across the Great Glen and east to the Monadhliath. A characterful Lochaber-edge Corbett accessible from Roy Bridge.

Park at the Glen Roy NNR viewpoint car park (NN298857), with its small layby and information board explaining the parallel roads. Continue up the glen road on foot for about 2km, then turn west off the tarmac and climb steeply onto the south-east shoulder of Beinn Iaruinn. A sustained heather-and-grass ascent leads to the summit cairn. Allow 4.5–5.5 hours.
Terrain
Tarmac glen road on the approach. The hillside above is heather and grass dotted with occasional rocky knobs on the upper crest. The top is a wide rounded dome capped by a substantial cairn. Drier underfoot than the western Lochaber Munros because Glen Roy sits in a partial rain shadow.
In winter
Snow lies well on Beinn Iaruinn's east-facing slopes through midwinter. The wide ridge gives easy walking under cover with no avalanche issues on the standard line. The Glen Roy road slows when iced but stays driveable. Modest cornicing develops on the north-eastern lip of the summit dome — give the edge a wide berth.
This hill is in the Creag Meagaidh SAIS forecast area. Check SAIS forecasts in winter (December–April).
