You will probably come to this mountain after parking at Clydagh Bridge R87450 27780 A. From Clydagh the traditional route is a magnificent circuit taking Cush, Galtybeg and Galtymore with Cushnabinnia included as the last summit. This is however a fair test of stamina so be prepared. Also be aware the summit is not the spot height marked on the OS map. It is in fact a large cairn further west. For a more direct approach follow the way marked trail for L. Curra for some 3km through the forest to where it leads out to open moorland.. Go W up hill to a small but prominent Ring Fort R868259 B.Leave the way marked trail at this point and go SW up the broad spur of Knocknanuss, passing a large cairn en route. Continue up over Pt 766 to meet the wall marking the County boundary. Turn right and go out W across flat boggy ground to gain the high point.

The summit of Slievecushnabinnia is not located at the spot height marked on the OS map as 766m but at a higher point about 500 metres to the West. If you look at the OS map carefully, you can see that the true summit is inside a 770 metre contour. There is a large cairn on the true summit (R 85770 24000 C)(Approx 775m ASL) and Simon3 has a picture of it shown on this page. My photo shows the view from Galtymore showing the 766m spot height and the position of the true summit. On the old half inch OS map, the summit is shown in the correct position with a height of 2,549 ft. Perhaps the 766m spot height actually refers to the name 'Monacloghana' which is printed just below it on the OS map. Linkback: https://mountainviews.ie/summit/64/comment/2082/

It’s hard to know where the top of this mountain is. There is a very prominent cairn near the right angle of the wall, but it didn’t strike me as the highest point. I saw two more cairns over on the way to Carrignabinnia, and went over to investigate them. On the way the ground on the Limerick side of the wall was excellent, while on the Tipp side it was quite soggy. These cairns didn’t seem to be a highest point either but where excellent warning beacons to the steep drop beside them. I headed back to what I judged to be the highest point and, lo and behold, found a little cairn. I include a photo of what must be the top. From this I headed down the spur called Knockanuss. On way I found a very impressive yet seemingly incongruous cairn. From where I followed Lonely Planet’s directions to a grassy knoll, although I actually think it could be the ring fort marked on the O.S. map at R868258 E. From here I turned due east to meet a forestry fence and walked south along it until I found a stile to cross it. Beyond this fence there was a road and I turned left down it until I reached a V where there was a ruined chimney. I took the left at this V which took me back to the Clydagh Valley car park. The Galtees are a cracking range. Linkback: https://mountainviews.ie/summit/64/comment/2101/

Above 700 metres the ascent to the indiscernible summit of Slievecushnabinnia became smothered in low passing cloud. Ahead of me I saw another walker, he appeared and disappeared at intervals through layers of semi transparent mist. Try as I did, I could not catch him. Eventually the phantom vapourised completely as the visibility fell to a few metres. After visiting the many possible summits of Slievecushnabinnia I reached the boundary wall that runs along the top. I huddled in the right angle where the wall turns towards Galtymore. The wind howled most of the time I sat there and then in stunning moments of total silence all sound seemed to be sucked out of the mountains, if you strained you ear you felt you could hear the clouds rustle pass. These sharp transitions into silence left one with a surreal sense of quietude suspended on a sense of anticipation that at any moment the wind would howl again. Only once during my time at the wall did Galtymore emerge, flirtatiously beckoning invitingly over my shoulder for an instant, clear of mist, just as it had been when I climbed it in July.

Slievecushnabinnia, or at least points near it, have a great selection of views. You can see Galtymore and the edge of the fine scarp overlooking Lough Curra and ridge leading to Galtymore. From points near it you can see right into Lough Curra, and also along the northern slopes of the Galtees to the two northerly outliers: Cush and Knockastakeen.

This view shows the substantial cairn on top of the mountain and the wall stretching off to the east. The rock is red sandstone which is the predominant rock on most of the Galtees. The wall makes up the boundary between Tipperary and Limerick. Linkback: https://mountainviews.ie/summit/64/comment/557/
