The south coast is dominated by high cliffs, which rise to at Skate Point ("Rubha Sgait") in the south west. Barra Head itself is the southern prominence located mid-way along the south coast. The highest point of the island is Sotan, a Marilyn whose summit lies above high cliffs between Barra Head and Skate Point. This eminence is easily reached from the track that leads from Achduin to the lighthouse that passes just to the north of the summit, which is only from the cliff edge. The skerry of Bird Rock guards the coast far below. The lighthouse is located near the prominence of Sròn an Duin, just east of Skate Point and above the narrow chasm of Sloc na Bèiste (ravine of the monster).
