Cuilags
A 435m hill in the Orkney Islands with at least 150m of prominence — enough to feel like a real summit rather than a shoulder. The modest height belies the quality of the walking.

Standard route
Standard route
A steady ascent on island paths with sea views in multiple directions to the 435m summit. The walking is straightforward with clear views opening up as you gain height. Allow 2-4 hours.
Terrain
Island terrain varying from machair grassland to rocky hillside. Sea salt exposure affects the vegetation. Wind is a constant companion.
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.
