Standard route
heather moorland 50% · granite rock 35% · grass slopes 15%
From Lochranza, follow the Glen Chalmadale forestry track for a kilometre then climb the eastern slopes through rough ground to the summit ridge. About 8km return with 500m of ascent; three to four hours is comfortable.
Terrain
Bracken and heather on the lower slopes (vicious in late summer), then granite boulder fields and short turf on the summit ridge. A few steeper sections need hands for balance.
In winter
Snow accumulates on the north-east aspect from January and can linger surprisingly long. The summit boulders are slick when wet or icy — steady footing essential.
