At 582 metres (1,909 ft), Glendoo Mountain among the 40 highest summits in the Wicklow Mountains. The summit itself isn't particularly impressive and the terrain can be extremely boggy after rainfall. However, the hike to the top does provide exceptional views across Dublin and can be combined with a visit to nearby Cruagh Mountain.
