Height: 720 metres Duff Hill is the 96th highest summit in Ireland.

Summit Cairn, Duff with snow on corrie rim of Mullaghcleevaun in the background. Watch out for foxes in this area as there are several dens on southern slope burrowed under great granite boulders.

Duff Hill can be approached from Carrigvore and Gravale in a ridge walk that takes about four hours - starting and finishing at the car park on the Military Road south of the Sally Gap. The walk can be shortened by using two cars and parking a return car at the northern edge of the woods SE of Duff Hill or lengthened by continuing on to Mullaghcleevaun and descending at Carrigshou.
