Corranabinnia, near Mulranny, is the apex and the highest pt of the Glendahurk Horseshoe. It's a highly rated peak, noted for the fine ridge which extends to that of its SW top. There are staggering views of Clew Bay, Croagh Patrick and Achill.
Corranabinnia is far from roads hence there are few practical routes and these all include other peaks.

S. The most trodden route is the circuit of Glendahurk Valley, taking in the Bengorms and the 2 Corranabinnia’s (minor scrambling on a spectacular aréte between the two) Start anti-clockwise from L91061 97962 A or 300m further S where there is a stile on the right. Demanding 15k, ascent 1,000m, give about 6 hours.

NW. This potentially v boggy route starts at F86600 07169 B, near some old houses. Head SE from here crossing nearly 5k of bog before rising steeply to summit C’binnia SW top via its N spur. From here it’s a fine ridge walk NE to C. To get back to the start, head for Glennamong and take its NW spur to the beckoning bog below. Take care when crossing streams near the start as many of them have silted up and are more like slowly moving bog. 6 hrs+ for circuit.

A more ambitious circuit starting further E near Srahmore and centering on the Glennamong Valley is also possible. This takes in Tirkslieve, both Glennamongs, Corranabinnia and the two Bengorms, before dropping to the road near Furness. 20k+, with some road walking - 8 hours.

Notable tracks include track/3472, track/3551 and the long, circular track/3784. Linkback: https://mountainviews.ie/summit/98/comment/4858/

I walked this impressive hill in the fine spell of early September 2023, approaching from the S and parking at L 912 977 C next to the old farm building. Access to the open hill from here was over an adjacent stile and a gate at the far side of the field and then one more fence shortly after (I was unable to find another gate though). The route to Ben Gorm is clear to follow, next to a stream and some posts indicating the presence of a "mass rock" further up the hill. I never did find the rock, but the top of Ben Gorm was reached easily enough and when the cloud cleared for a while, the views E and N opened up, with Lough Feeagh below and Birreencorragh beyond, and the next two tops to the N , marking the way to Corranabinnia itself, with its head still in cloud for the moment. It looked fairly imposing for this solo walker, but as it turned out, the undulating route over the other two tops was an enjoyable trek over good , firm ground and rocks, with the odd easy semi-scramble in places. Approaching Corranabinnia and being careful in the fast moving cloud scudding across, to keep well away from the steep drop on the E side, there was a bit more rock-hopping involved which needed a little concentration. I reached the summit in about 3 hrs 45 minutes, taking it steady. Looking across the ridge walk to the SW top, it was an easy decision, especially in poor visibility: No chance! The approach looked pretty intimidating - more so than I was expecting from walk descriptions and photographs - but I expect the conditions added to that impression. In any case, I decided to leave that top for another day and another approach. Looking back down the inbound ridge and deciding on a return route, I dropped down from the nearest col at approximately F 914 977 D. In retrospect, I would not recommend this route in anything other than good , dry conditions. It calls for some concentration and a more sensible route would probably be to either re-trace the outbound route and accept the extra ascent involved, or take the last col before reaching Ben Gorm, which seemed to offer a more gentle and grassy descent. In any case, I followed the infant river from the top of the valley for a good hour or so, and the going was surprisingly good and firm underfoot. However, eventually the river takes a W turn into the forestry and the path becomes a bogfest of unresolved groundwater; there is nothing for it but to walk on adjacent to the fence for another hour or more and then cross SE from the end of the forestry , and cross the stream to reach the starting point. I would advise anyone dropping down from one of the cols to maybe stay as high on the flank of Ben Gorm as possible to keep the solid ground underfoot and cross the stream higher up to re-join the path. Total elapsed time about 6hrs 30min. All in all, a great climb, and definitely a return visit to tackle the SW top in better conditions to enjoy the views across this superb hill range.

This summit ,while 5 metres lower than than the highest in the range,remote Slieve Car, is the high point of the western Nephinbeg ridge. It commands splendid views, particularly south over Clew Bay and west toward Achill (lower photo) It also forms part of a fine 20km. ridge circuit including BenGorm and Glenamong.
This took almost 8 hours using 2 cars, one left in a large recessed entrance at L956 985 E and finishing in the carpark at the start of the Bangor Trail. Without cars a somewhat longer variant could be done from Traenlur YH, using the ford at F 947 024 F. Top photo shows the view west from near Corranabinnia main top showing the ridge to the SW top.

A MountainViews walk took place on Saturday 7th October. It was led by MountainViews member Liz50, and 17 hardy souls set off on this tough and demanding walk. We completed a counter-clockwise loop of the Glendahurk circuit in the Nephin Begs. Two members planned to join us as far as Ben Gorm NW Top, and the remaining 15 continued on the full circuit.

From L91061 97962 A we started with a bog walk to Ben Gorm (582m). This early ascent of over 530m over tiring bog meant that (A) we got this nasty slog out of the way early, (B) we could approach the infamous Corranabinnia arête later from a more favourable NE-SW direction. Given the cloudy and sometimes wet conditions, and mix of ability amongst the group, it was a wise decision by the experienced Liz50 who has traversed the arête from both directions previously and understood the best approach for our group.

After Ben Gorm we dropped 230m to the col and ascended over 110m to Ben Gorm NW Top. Looking back at Ben Gorm from Ben Gorm NW gave another reason to be glad of the counter clockwise route – imagine facing that 230m haul up Ben Gorm towards the end of a clockwise walk?!
The 300m climb from the col below Ben Gorm NW up to the main Corranabinnia summit was demanding and included some light scrambling over some steep rocky ground. The infamous views were denied to us by cloud but the delicious home-made chocolate and oatmeal treats being passed around kept us otherwise engaged! With approx. 950m of accumulated ascent so far under our boots we knew that the majority of the climbing was done but that the section requiring most concentration lay ahead.

Liz50 ably navigated us down towards the arête. It suddenly appeared as the ground gave way on the right to sheer and craggy drops that disappeared into the mist below. The ground to the left (south side) fell away steeply in a tumble of rocks and steep grassy slopes. Liz50 brought us along a narrow route on the southern side several metres safely below the jagged and brooding arête. While protected from the worst of the exposure, concentration was needed as we delicately clambered over and around rocks and focussed on not slipping on the wet ground. Time momentarily took on a different speed as it was all about one slow foot and handhold in front of the other. Eventually we reached a place where a scramble up a very steep grassy slope took us suddenly onto the summit area of Corranabinnia SW. Despite the cloud we had seen enough of the arête to appreciate its challenge, and to feel a sense of achievement having completed the crossing.

Several kms of bog walk down the southern spur of Corranabinnia SW brought us back to our starting point. The cloud cleared at around 450m allowing us to once again admire the view of Clew Bay and out to Clare Island. At over 1000m of ascent, this 16.5kms, 6+ hour route over Corranabinnia is demanding, and the arête should be approached with caution. But what a great walk!

In my opinion, the Corranabinnia horseshoe is one of the most challenging hikes in the west of Ireland, with in excess of 1000m height gain over about 14km. The ascent to Bengorm (582m) is gradual but the soft peaty underfoot conditions make it a real slog. The final climb up to the trig station at the summit of Corranabinnia is also challenging. The arete ridge between Corranbinnia main top and SW top is not as intimidating as I expected - but maybe that's because the cloud didn't allow us to see the full extent of the drops on either side! The photo shown is looking across the ridge to the SW top and believe it or not is taken in the same direction and not far to the left as milo's photo on the same mountain!
