Standard route
heather and bog 65% · grass slopes 25% · rocky summit 10%
A short steep climb from the A815 north of Strachur. Forestry tracks help with the initial ascent but rough open ground is unavoidable for the upper third. Round trip 2-3 hours.
Terrain
Mixed forestry rides, heather and grass. Boggy hollows on the southern flank can be avoided by following the ridge directly.
In winter
Frost firms up the heather and makes for pleasant walking. Genuine snow cover is unusual; gaiters and a torch are typically all you need.
