Elegug Stacks are two limestone towers standing just off the Castlemartin cliffs, packed in spring and summer with breeding guillemots and razorbills — ‘elegug’ is the local word for guillemot. They lie within the Castlemartin firing range, so access along the road and cliff path depends on the army’s timetable; check whether the range is open before setting out. The Green Bridge of Wales is a few steps further along.
