Summary for Slieve Rushen (Sliabh Roisean): Heather-topped hill with good views

Picture: The 'summit' in a winter coat.
It is possible to drive up a narrow forest road to Corn WF (H23164 21626), (Corneen Wind Farm) where there is parking for a few cars. This will take you to about 350m ascent, however after that, depending on conditions, it can still be a difficult walk to the NNE through 1.3km of heather and reeds. The high point is a slightly elevated mound of heather sticking up out of the bog. Excellent views to the west towards Cuilcagh, Benbrack etc. Despite the relatively short distance, allow 1.5 hours return journey to car, thanks to the terrain.

Busy hill with remote top

Slieve Rushen is situated in both Cavan and Fermanagh. The county boundary – and boundary between Northern Ireland and the Republic – crosses Slieve Rushen, although it doesn’t come closer than 1km of the summit, meaning that the summit itself is in Cavan. Although only 404 metres in height, Slieve Rushen is a large hill, measuring about 6 kms at its widest, and 10 kms at its longest. Slieve Rushen has attracted all sorts of commercial activity, including wind farms, quarrying and forestry operations. I discovered a full size two lane tarmac road complete with central white lines running east- west at the 200 metre elevation mark, even though it is not marked on any OS map. This was clearly built for the heavy machinery driving around the hill. I discovered it at A (H23425 20139) and I followed it east until it was blocked by a barrier at B (H26154 20501). I could only gaze at it disappearing into the distance ahead as I turned my car around. A warning sign written in both English and Polish was a reminder of the Celtic Tiger that would have brought so many workers to the commercial activity on the hill. There are several tracks running off the road which could give access to different areas of the hill. Despite all of the evidence of commercial activity, the summit itself is a pristine area of bog and heather, with no evidence of previous walkers. There aren’t even any animal tracks to help you through the sometimes difficult heather.

I opted to park at Corn WF (H23164 21626) and take a walk across the bog for about 1.2km to the summit. There is room for a few cars here, and there are a couple of wind turbines. There are no gates or keep out signs on the approach. The last few hundred metres up to this parking spot is a steep track. From here it is a case of heading NW over the bog to the unmarked summit. The ground is curiously spongy and it is slow going in places. It was freezing when I was there, and still soft, so I imagine it’s wet and difficult at other times. Slieve Rushen is a hill with no discernible high point, with a flat heathery summit unmarked by even a stone. There is a slight heathery bump about 80 metres north of the given MV grid ref which may be slightly higher than the surrounding bog, but I think a metre here or there wont matter to many.

There are quite good views of the surrounding plains, but it is the view west to the Cuilcagh – Benbeg – Benbrack area of upland that really catches the eye. These can all be clearly seen along with further outliers like Mullaleam and possibly even Belmore Mountain to the North West. There are no doubt several other routes up this hill, which could make use of the forestry along the southern and eastern slopes, although I get the feeling the summit is not visited very often. One note of caution. Despite the many wind turbines on the hill, the featureless nature of the summit area with nothing for 1km in any direction means that this could be a tricky place to be in poor visibility. Linkback:

Not a bad way to finish a local 100!
by Geo 8 Sep 2013
After a damp Slieve Glah and a particularly horrendous high-step over the vegetation on Bruse Hill, we followed wicklore's excellent directions and grid references up to the end of the track on Slieve Rushen. The reward after number's 98 & 99 of my local list was a nice easy, soft walk across the bog to the 'summit' of my 100th local hill woohoo! Lots of whooshy wind turbines and the sound of boy racers burning rubber on the access roads below us were our soundtrack. It was hard to exactly pin-point the summit but we went with the little 'bump' impaled by a piece of timber. Linkback:

Snowed under
by Colin Murphy 23 Jan 2023
It's amazing sometimes how winter can transform an otherwise ordinary little hill into something beautiful. Slieve Rushen is a tramp through heather to a broad mound with a slightly smaller mound marking its high point. But the views from the top on this snowy January day made the effort worthwhile.
