Corbett · North-West Highlands
Sail Mhor
Sail Mhòr — 'the big heel' — is the 767m sandstone Corbett standing immediately west of An Teallach above Little Loch Broom. The mountain is in many ways An Teallach's outlying buttress: the same Torridonian sandstone, the same dramatic ridge architecture, just on a smaller scale. The west face plunges into Coire na Feòla in dramatic cliffs; the north ridge gives a fine summit approach with continuous views across to An Teallach's pinnacles. A useful follow-up summit for parties who have already bagged An Teallach.

Park at the Ardessie falls layby on the A832 (NH050897), about 3km north-west of the Dundonnell Hotel. Follow the path up the south side of the Allt Airdeasaidh, climbing past the spectacular falls and into Coire an Eich. From the corrie, climb south-west onto Sail Mhòr's north ridge and follow it to the summit cairn. Return reverses the line. Allow 5–6 hours.
Terrain
Excellent path past Ardessie Falls — among the more impressive cascades in Wester Ross. The corrie above is rough heather and grass; higher up, the route crosses sound Torridonian sandstone, with the west side dropping sharply into Coire na Feòla. The summit cairn sits on a small rocky outcrop.
In winter
In winter Sail Mhòr's sandstone ridge ices up readily and the west-face drops become serious. The Ardessie path freezes hard, especially around the falls. Atlantic systems coming up Little Loch Broom deliver punishing weather. In firm conditions a striking short winter day with An Teallach as a backdrop.
This hill is in the Torridon SAIS forecast area. Check SAIS forecasts in winter (December–April).
