Sgurr Dhomhuill Mor
Sgurr Dhomhuill Mor — Donald's Big Peak — is the highest summit of the Ardgour group north of Loch Shiel, rising to 713m in a tangle of rough, little-visited ridges. Its prominence and isolation make it one of the wildest Marilyns in the region. From the top the eye runs across Moidart's lochs and forests to the Rough Bounds of Knoydart, with Beinn Resipol prominent to the south.
Gaelic: “sharp peak, big” · Pronunciation: skoor dhomhuill more

Best approached from the south end of Loch Doilet or from Polloch on Loch Shiel, climbing rough open hillside north then west to gain the south ridge. The final summit slope is steep grass and broken crag. Allow seven to eight hours for the full round.
Terrain
Lower slopes are deep heather, peat and felled forestry on the Polloch side; higher up the ground firms into knobbly schist and short turf. Plenty of small crags to weave around on the summit ridge.
In winter
In good cold conditions the upper slopes hold useful snow and the summit gives a fine winter day, but the long approach and lack of paths mean a full kit including axe and crampons. White-out navigation on the broad summit demands care.
This hill is in the Glen Coe SAIS forecast area. Check SAIS forecasts in winter (December–April).
