Standard route
heather moorland 55% · grass slopes 30% · rocky summit 15%
Start near Kilmarie or the head of Loch Slapin and climb the broad north-east ridge over rough grass and rock. The summit reveals a panoramic view of Bla Bheinn, Marsco and out to Rum. Around 8 km return.
Terrain
Pathless heather, peat hags and boilerplate basalt slabs make navigation slow. Boots cope better than approach shoes on the loose upper ground.
In winter
Snow rarely lingers but freezing rain glazes the slabs. Strong westerlies funnel up Loch Slapin and make the ridge feel exposed even at modest height.
