Climbing the Coire a' Mhuilinn Path
From Ullapool, follow the A835 to Braemore Junction and the A832 west to Dundonnell on Little Loch Broom. Start from the Dundonnell Mountain Rescue layby, cross the road and take the path through gorse and up Meall Garbh into Coire a' Mhuilinn. Steep scree and boulders lead onto the ridge and a short Class 2 climb reaches the trig point, with a dramatic view of the Corrag Bhuidhe pinnacles. Usually combined with Sgurr Fiona; the full ridge traverse is a Grade 3 scramble. The upper corrie holds snow into spring, and wind funnels across the crest. Carry a map and compass, as there is no signal above the road.
