Park at W01491 77290 A, walk up the track, head for the summit, admire turbines and Crohane. Linkback: https://new.mountainviews.ie/summit/799/comment/5558/

Park at the Millenium Forest car park at W04507 78877 B (on the western side of the road). Walk back to the car park entrance and keep an eye out for a narrow forest trail just to the south of the main one. Follow this trail over 15 mins until it eventually meets the original track at approx. W03426 78984 C. Go left here and keep left at the next intersection which you will shortly encounter. Keep on this track until you meet a fire break on the left about 200m after a ruined shed. The break is at approx. W02671 78738 D. Go south through the firebreak and head for the obvious high ground. You'll pass 4 or 5 fences en route and travel across a few broad and relatively dry ledges as well as the ubiquitous false summit. I got to the top in under 2 hours. From here there are really great views mainly to the north, south and west.
I descended in a easterly direction, veering south east after 500m. The going was easy and I was down at W04291 75914 E in no time, scratching my head as to how to descend to the main road. I decided on heading down very steeply in a NE direction to the beckoning flat farmland below. It wasn't the greatest decision I ever made as the descent was very steep, wet and rough and there was a stream going parallel to the road which proved tricky to cross. If I was to stand at that point again I would head in a more southerly direction to give a safer descent, albeit with a longer road walk back to the car. Much better if you had a second car or a bike to avoid walking back on this busy, narrow road.
The circuit took 3.5 hours and was most enjoyable - if rugged, isolated boggy terrain is your thing I recommend it strongly. Linkback: https://new.mountainviews.ie/summit/799/comment/21875/

I followed markmjcampion's route description uphill from the northern side. Terrain was tricky enough, especially with very saturated ground. I didn't fancy going back the same way so followed some quad tracks down towards a fence and found a nice track off. It did mean a long walk back on farm / forest tracks but it was probably just as fast as navigating steep wet rocks and a river. Track 5360 if anyone else want's a circular route.
