The summit overlooks great areas of Cork farmland and some of Kerry. There is a good view of the gracious Paps to the SW. It can be reached from the Duhallow Way to the north and east, with particular starting points such as W196893 A or W177850 B. Or make it part of a ridge walk from Caherbarnagh from which it is separated by around 650m and a NE facing corrie.
Going is good on the summit with short grass or heather though some of the lower slopes are harder. The exact top is somewhat vague. Linkback: https://mountainviews.ie/summit/157/comment/4917/

The Derrynasaggart mountains would not win any awards for their looks.
At first glance a vast, sodden expanse of bog carpeted in rough Ling and Tussock Sedge
that have made many a better man than me reach for his Lucozade.
Look again though and the rich geological history of the area comes to light.
The sharp edge of Devonian Old Red Sandstone of the Derrynasaggarts wedged against the
older Namurian rocks to the north divided by the Killarney/Mallow faultline.
The rich glacial deposits piled against the northern slopes recall times when these
hills carried their own receding Ice-cap 130,000 years ago and somewhat obscure the impressive
fault scap which is visible in a only few places such as Lough Gortavehy.
To the west the sensual Paps contrast with the violent, twisted slopes of Crohane and Stoompa rising above the tranquil Lough Guitane
betraying the outpourings of lava and volcanic deposits in the late Devonian era that formed them.
But enough of the geology lesson, what of the views? what of the views!
On a clear day in early March, the snow capped Kerry Highlands....... magnificent!

Wish the view was as good as the photo by Jackhill the day I took my camera. Going up can often be easier than coming down and today we came down from Glanaprehane on the closer fallaway ridge by moving out to the end of it turning right near the end and then left again. Much easier to go up. The boggy soft ground is a help but a few more rocks would make a man feel safer on the way down. To go up, in my opinion its one of the best challenges to reach the higher Caherbarnagh apart from taking it straight on from the coom (very hard) or firstly ascending Stoukeen considering any ascent from the Clydagh valley is pretty damp. This said I would alternatley recommend an ascent from W177 850 B as the driest from the Clydagh valley which is beautiful and long valley which is nice and quiet as there is only one way in and out for normal traffic.

Approached Caherbarnagh NW from Knocknagowan via Caherbarnagh, I had planned to head on to Knocknabro and back up the road in Clydagh valley, but the going is so tough over the tussocky boggy ground from Clydagh I decided to head back the way I came.
The views to the North are lovely and the valley between Caherbarnagh NW and Caherbarnagh looks like a great climb, I'm sure it's horribly slippery though.
Reaching the summit of Caherbarnagh NW, I came across a tiny cairn which needs some urgent help, so if you've got some room in your backpack for a few rocks, you know what to do. Linkback: https://mountainviews.ie/summit/157/comment/6745/
