Derrybawn has a great situation, looking into four glacial valleys and above the well known Glendalough lakes. The summit is the north end of a 1.6km ridge, the best formed in Wicklow. Many of its lower slopes are planted with mature oak trees.
From the north east it is possible to ascend from the large lake's edge at around T1118 9640 A initially using the well developed tourist and forestry paths that go beside the Poulanass waterfall and then, more steeply, aiming for a corner in the forest at T1146 9568 B over small paths. There is an eroded path through high heather to the top. Another possible ascent is from the "Shay Elliott" memorial at around T129 922 C, going W over Cullentragh Mountain (not currently an MV listed summit) and then turning NE on a seriously eroded path through high heather to the south end of the Derrybawn ridge.

Glendalough can be a truly magical place - especially when there are no tourists there. I was lucky to arrive at the foot of Derrybawn (whose western slope is visible in the background) just after sunrise on an autumn morning in 2017. The prevailing weather conditions had contrived to create an eerie mist illuminated by bright early morning sunshine. I can see why the monks who long ago inhabited this place made a spiritual connection with it. Linkback: https://mountainviews.ie/summit/537/comment/19960/

Derrybawn is famous for its 1.5k ridge stretching SW from the summit. Of course there's many more spectacular ridges elsewhere in Ireland such as the Beenkeragh off Carrauntoohil, the Corranabinnia ridge, the Turks, Slieve League, Bhinn Láir and the Teeromoyle Tooth. But if you live around Dublin, the Derrybawn ridge and the Faninierin ridge are really all there is - The Derrybawn ridge being much easier to incorporate into a looped walk.
Sadly the ridge has suffered over the years from trail erosion. There is now a path along its length which has formed entirely in the last 30 years.

Taken from along the ridge, the picture shows what looks like a mountain rescue drill, with the helicopter hovering over the summit.

As far as I can tell, the summit right skyline is Ballinafunshoge. Linkback: https://mountainviews.ie/summit/537/comment/2686/

Derrybawn is the oak-footed southern mouth of the Vale of Glendalough. Steep on its north side, its easily reached from the carpark at the Glendalough Visitor Centre or the car park between the two lakes.
I spent around two years in the 70's mapping it for Orienteering purposes - I know Derrybawn in all its seasons and learnt a bit of its history from the former owner of Derrybawn House.

The view here is from its summit towards the west. The tongue of water to the right is part of Glendalough Upper Lake. To the left of it is the Spink. Skyline right is the SW spur of Camaderry. Linkback: https://mountainviews.ie/summit/537/comment/2685/
