Lugduff

Lugduff at 652 m, is the 154th–highest peak in Ireland on the Arderin scale, and the 186th–highest peak on the Vandeleur-Lynam scale. Lugduff is situated in the southern sector of the Wicklow Mountains range, and forms a broad horseshoe around the Upper Lake of the Glendalough valley with the mountains of Mullacor 661 m, Conavalla 734 m, the hydroelectric station at Turlough Hill 681 m, and Camaderry 699 m.

Lugduff's steep western slopes, have a distinctive "corrugated" profile, and form the deep valley sidewall of the eastern flank of Glenmalure; Lugduff's western walls also sit at the T-junction of the Fraughan Rock Glen hanging valley with the Glenmalure valley.

Just below Lugduff's summit, lies the popular 8-kilometre boarded mountain path of The Spinc White Trail around the Upper Lake of Glendalough. To the south of Lugduff is the subsidiary summit of Lugduff SE Top 637 m.
