Park at a small field entrance at R94525 53427 A on the narrow roadside where there was room for only one car.Walk back up the road towards Hollyford and cross the first gate to your right.
Be aware this is farmland so access may not always be possible so if you can ask the farmer.
Follow the fence/ditch on the left uphill, initially next to a tree lined stream, crossing two fences and a farm track to the summit which is marked by a few stones next to a wire fence.
An alternative start point is R955 542 B where there is ample parking by an abandoned house as oldsoldier mentions. From here it is a short walk up a rough track, a grassy pathway and across a field heading for a large wind turbine which is part of Glenough Windfarm which officially opens in June 2012. The actual summit is a short walk behind the turbine by a clump of trees. Linkback: https://mountainviews.ie/summit/771/comment/5530/
