From Karl og Kerling you can return to Vesturdalur by walking a 7km trail around Eyjan, a mesa-like ‘island’ covered with low, scrubby forests and small ponds. Follow the river south to Kallbjarg, then turn west along the track to the abandoned site of Svínadalur, where the canyon widens into a broad valley, and follow the western base of the Eyjan cliffs back to the Vesturdalur parking area.
