Standard route
heather moorland 60% · grass slopes 25% · rocky summit 15%
A direct ascent from the A83 at Furnace climbs steeply through hazel woodland before reaching open hillside above. The line is short but unrelentingly uphill; allow 2 to 3 hours return.
Terrain
Lower slopes are mixed woodland and steep grass. Above the trees the going is short heather, with bare slabs at the rocky summit knoll. The gradient is the chief obstacle.
In winter
A short hill but the steep grass slopes can be greasy in rain or treacherous when frozen. Avoid the direct approach in icy conditions.
