A small, uninhabited marine island lying 3 km west of Aughris Point, off the west coast of County Galway. The island, with a largely sheer cliff coastline, rises to 60 m in height. It is of archaeological interest for its ancient monastic settlements.
The cliffs and undisturbed coastal grasslands of High Island provide an important site for breeding seabirds. Fulmarus glacialis also breeds in nationally important numbers (350 pairs, 1987).
