Standard route
island track 20% · rough gneiss 40% · rocky ridge 30% · summit area 10%
Park near Bunavoneader on the A859. Follow the old whaling station track east into Glen Ulladale, then climb the south-west spur directly. The upper ridge winds round small lochans onto the summit cairn.
Terrain
Stripped Lewisian gneiss slabs, peat hags and tussocky grass — classic Hebridean walking surface. The summit area is intricate and there are several knolls before the true top.
In winter
Snow rarely sticks at Hebridean altitudes but ice on the gneiss slabs is treacherous. The hills here catch the full force of North Atlantic gales — wind, not snow, is the season's main hazard.
