I did an evening ascent of this hill in early September 2018, estimating that I would comfortably complete the first top and get back with plenty of daylight. Parking at Belfarsad Bridge where there is a good space for a couple of cars L748 985 C, I followed the road south and accessed the bog approach behind the house at L748 981 D (after asking permission from the owner) and heading broadly SSE towards the west flank.
In hindsight, the approach described from the bog track north of the bridge would probably have been easier, but I hadn't done my research here at that point.
No matter, the walking was not too heavy underfoot until the steep climb through dense heather began. There was the odd bit of a sheep trail , but basically it was a case of ploughing on with frequent stops to get a breath and look back at the views opening up of Achill Island, and watching for the regular squalls approaching from the Atlantic so that I could crouch down and stay as dry as possible until they passed quickly. Stupidly I had not put my waterproof overtrousers on although managed to get the jacket donned before the first deluge hit !
After about an hour or so, the approach ridge was reached, and the going became much easier through short grass and rocks, to reach the trig point and take a few shots before the light started to fade. I was lucky that the weather cleared for the last of the day, giving spectacular clear light and tremendous vistas back to Slievemore, Croaghaun and Achill Sound nearby, and the expanse of Ballycroy National Park and the Nephin Beg range beyond Bellacragher Bay.
The return was broadly by the same route, but I would suggest the bog road mentioned above. It might be a bit longer, but looks less arduous. Total time taken 3-4 hours with photo stops and general dawdling and gawping at the top.
Definitely one for a longer exploration at another time, taking in Slieve Aghkerane and the rest of the ridge.
I climbed Slievemore the next day – and was blessed with glorious weather - but I would rate this hill even higher for scenic appeal. Highly recommended as an area and an individual hill ascent. Linkback: https://mountainviews.ie/summit/405/comment/20797/
