Knockcraugh Hill has left its mark on me, or rather several!
Approach this hill from the main road beyond Nad turning off at W43042 86051 C.
You will be on a paved road for a kilometer and after that a gravel covered forest track.You can follow this track down the other side of the hill to W40198 82769 D but the surface is truly terrible.
I started at a forest entrance W40556 85813 E and followed a good forest road to W402270 F 86067, went left up a ride to W39898 86028 G and left again up a ride to the summit. These rides are awful , full of soft ground, bog , briars and thigh high grasses that seem to tangle your feet with every step. The summit (if you can find it for sure) seems to be in a dense clump of conifers.
Looking at the map now perhaps there is an easier ascent along the track to the west?
The photo shows I hope the density of vegetation at the summit .
On the plus side it only takes an hour to bag , but its been a long time since I've been so wet, dirty and sore. Linkback: https://mountainviews.ie/summit/676/comment/4225/

This summit now has become very easy to access due to the construction of a windfarm access is via road at W3886383768 A which has now been upgraded and no problem to drive up to the windfarm roads at W3943885201 B in actual fact i drove to within 20 meters of the summit which has now been leveled and is now home to Turbine 3 . No problem finding the summit now folks. Linkback: https://mountainviews.ie/summit/676/comment/18297/

Expecting a horrid experience I was pleasantly surprised by the route from the west.
There is a small road at W38850 83800 H which turns into a rough forestry track, it's drivable in a normal car up to about W394 852 I where there is space for about 2 cars to park. The road continues if you got something a bit more robust to a small boggy track at W39806 85448 J. This track brings you within 75m of the summit, then you need to dodge through some trees to reach the co-ordinates and there is nothing to mark your achievement, but it's a 20 min bag if you must.
