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.

[5] Just over 3 km to the east-northeast of Cruach Mhór, across a sharp notch, is the lesser peak of Cnoc an Bhráca 731 metres (2,398 ft).

[2][5] On the summit of Cruach Mhór is a stone grotto built by a local farmer who hauled up the cement on his back, and its small statue is changed every year.

[7] Cruach Mhór does not appear in the MountainViews Online Database, 100 Highest Irish Mountains, as the prominence threshold is over 100 m (328 ft).
