Easiest way to access the summit is to park at R402304 D, outside the forest barrier. There is also another barrier right across the road with plenty of room for parking. Continue up the trail. Views are restricted but after approx 10 minutes you emerge where a large amount of treefelling has taken place. Good views over South Limerick / North Cork on a good day. Continue on this trail until you meet a fork at R414309 E and keep to the right. After about 5 minutes look out for a large clearing area [probably a turning circle] on your left.
Turn left here and keep to the right of the clearing, and scramble up the steepish bank into the trees. You are approx 80 metres from the summit from here. the trees are fairly close together here but somebody has kindly removed the lower branches so access is fine. Summit trig will be on your right on a mossy mound. Sadly no views as completely surrounded by trees. to return retrace your steps. 1 hour approx.

I lived about 1km north of Corronoher from 1960-1971 and climbed it many times. At first there was no plantation or trig point, that happened in the mid 60's I think. There used to be excellent views across the county and even catch glimpses of the Reeks in Kerry. My grandfather was proud to have climbed it in his 80's.

Hi eamonoc, I had forgotten the car hidden in the trees. Yes it was there when I ascended. youre right about the descration of the hills. Sadly not the first out of place motor I've come across on my wanderings. I followed a trail of car parts up to Corran hill on the Nagles. Another car in an impossible location [ the effort it took to get there!!] on one of the Shannon summits, and a lawnmower in the absolute middle of nowhere in the Boggeraghs. Still none of these are a patch on Peter Walkers jetski on where the name escapes me now. Pity, but I suppose hardly surprising. Linkback: https://mountainviews.ie/summit/1184/comment/18019/
