Djouce at 725 metres (2,379 ft), is the 74th–highest peak in Ireland on the Arderin scale, and the 91st–highest peak on the Vandeleur-Lynam scale. Djouce is situated in the northeastern section of the Wicklow Mountains, and dominates the views of the Wicklow Mountains from Roundwood to Newtownmountkennedy. Djouce is one of a few Irish mountains for which the Irish Office of Public Works (OPW) maintain a boarded mountain trail, using railway sleepers, from its base to a point close to its summit; making the mountain even more accessible to the public, but while also protecting the underlying bog and soil from human erosion. Djouce is popular with hill walkers, and it lies along the 131-kilometre Wicklow Way; on its southern slopes at a senic viewpoint is the J.B. Malone memorial stone, dedicated to the creator of the Wicklow Way.

In these lists of mountains in Ireland, those within Northern Ireland, or on the Republic of Ireland – United Kingdom border, are marked with an asterisk, while the rest are within the Republic of Ireland. Where mountains are ranked by height, the definition of the topographical prominence used to classify the mountain, is noted. In British definitions, a height of 600 metres (1,969 ft) is required for a mountain, whereas in Ireland, a lower threshold of 500 metres (1,640 ft) is sometimes advocated.
