Reached only by chartered boat from Castlebay or Mingulay landings, weather permitting. From the usual landing place at the bay, climb pathless grass and rock slopes to the 197m summit. Allow 2-3 hours on the island.

Terrain

Hebridean maritime grass, rocky outcrops and bird-burrowed turf on a steep-sided uninhabited island. Cliffs around much of the perimeter — keep well back from edges. No tracks.

In winter

Winter visits are effectively impossible — boat operators do not run, and Atlantic gales lash the island. Summer-only objective in settled weather.
