Tonduff (Irish: Tóin Dubh, meaning 'black bottom')[2] at 642 metres (2,106 ft), is the 169th–highest peak in Ireland on the Arderin scale,[3] and the 202nd–highest peak on the Vandeleur-Lynam scale.[4][5] Tonduff is in the far northeastern section of the Wicklow Mountains, in County Wicklow. The main flat summit is sometimes listed as Tonduff North, while the subsidiary summit, Tonduff East Top 593 metres (1,946 ft), is sometimes listed as Tonduff South.[2][6] Tonduff East Top has a prominence of only 15 metres (49 ft), which just qualifies it as an Arderin Beg.[7] A bog on the western slopes of Tonduff, the Liffey Head Bog, forms the source of the River Liffey; bogs on the southern slopes of Tonduff, forms the source of the River Dargle.[8]
