Cruach Mhór is at the far eastern section of MacGillycuddy's Reeks in County Kerry, Ireland's highest mountain range. It is the first major peak in the MacGillycuddy's Reeks Ridge Walk when started from Kate Kearney's Cottage in the Gap of Dunloe. The ridge between Cruach Mhór and Cnoc na Péiste , is marked by The Big Gun at its centre, and is considered as offering some of the most exposed and serious hill walking in Ireland (equivalent to The Bones on the nearby Beenkeragh Ridge). The Macgillycuddy's Reeks Ridge Walk continues along this ridge to Maolán Buí and on to Carrauntoohil, Ireland's highest mountain.
