MacGillycuddy's Reeks (Irish: Na Cruacha Dubha, meaning "the black stacks") is a mountain range in County Kerry, Republic of Ireland. Stretching slightly over 19 km (12 mi), it includes the highest peaks in Ireland and the only peaks on the island that are over 1,000 metres (3,300 ft). The highest of these is Carrauntoohil (1,038 m), followed by Beenkeragh (1,010 m) and Caher (1,001 m). The range also includes many other Hewitts (peaks of over 2,000 ft). The mountains, part of the Armorican Highlands, are of glacial-carved Devonian sandstone and are on the Iveragh Peninsula near the Lakes of Killarney.
