Standard route
Standard route
A short, accessible walk with Atlantic exposure and views to neighbouring islands to the 228m summit. The low altitude and gentle gradients make this achievable in 1-3 hours.
Terrain
Mixed island landscape with coastal rock, peat and grass. The sea is visible from most points on the walk.
In winter
Maritime climate means mild winters with little snow but persistent wind and rain. A good option when mainland hills are in full winter conditions.
