Climbed Knockbrack on the 08/03/2009, from a different side to those in other comments. Left car at Gowlane Cross (91751), about 2 miles from Kenmare town (past the Church and schools and straight on), and walked north east along the tarred road. After approximately half a mile, there is a large newly build shed just off the tarred road on the left hand side (924758 C) with a gate in front which is just closed by a wire. I left the tarred road and went through the gate, past the shed and up a track that leads from behind the shed along by the base of Knockaganuish Mountain on the left (West) wide and on to Cummerslaun Lake. Near the lake a river crosses over the track, and at this point (925774 D) I turned off the track and followed the river back to its source, Lough Nambrackdarrig, which is in the valley between Knockrower, Dromdiralough and Knockrower. Going wasn't easy as weather was very bad, snowing and windy, but terrain was fine - though should bear in mind that the north side of the river has a track carved by quad bikes and there are few natural fording points in the river during rain. When I got to the lake, (944783 E) I headed south east across about 50 yards of very boggy ground towards a very distinct rock on the west side of Knockrower which is clearly visible against the sky, and from there made my way east to the summit. Some rocks and boulders, and one set of crags about half way up and which are easy enough to get around, but otherwise no real obstacles. The top is not very clealy defined, no cairn, so its a bit of guessing and sizing one outcrop of rock against another. In wandering around the top I found the two lakes marked in all maps near the top, on the day I was there one was all but frozen over. Some spectacular scenery from the summit, though the conditions were alpine with snow and a strong gale which almost bowled me over a few times. No big cliffs though, pretty safe there. Walked down pretty much the same route, though this time circled Lough Nambrackdarrig to the east and north before finding the river again and following it back to Cummerslaun. Overall it took about 4 hours, though stopped a lot to take photos. Linkback: https://mountainviews.ie/summit/255/comment/3635/
