Beinisvørð (sometimes written Beinisvord) is a 469-metre sea cliff on the western side of Suðuroy, rising sheer from the North Atlantic to form one of the most dramatic coastal profiles in the Faroe Islands. From the sea it is an almost vertical wall of basalt and grass; from the village side it is a steep green mountainside scored with the lines of old paths.
You can walk to the top from Sumba in about 40 minutes — a steep ascent with no technical difficulty but requiring good boots and a head for exposure at the top. The views from the summit are immense: the whole jagged west coast of Suðuroy running north, the Atlantic horizon, and on clear days the distant shapes of the neighbouring islands. The viewpoint at Hesturin, accessible by road, gives a good impression without the full climb.
