Birreencorragh is probably one of the more accessible of the higher Nephin Begs in my limited knowledge and experience; having walked only a couple of the others so far. My visit coincided with glorious weather in early September 2023, and I used Simms and Whilde's "Walk Guide - West of Ireland" as my reference for access and parking, which proved to be very reliable. So I approached from the NE , turning off the Castlebar-Bangor road R312 at an unsignposted crossroads at G 042 118 H and then left immediately after crossing the Deel River towards the townland of Glendavoolagh, which is also marked on a stone at the turnoff. Follow this narrow road as it progresses into the narrowing valley, Park at G 022 096 I . Dropping down to the river, I found the crossing fairly straightforward after a few days of dry weather. There is then a short and reasonably steep pull up through heather until the gradient eases off fairly quickly. Thereafter the ascent is over decent, firm ground, as one makes progress up the gentle N-S spur to reach the natural break point with a cairn and the remnants of the fenceline at G 021 071 J which disappears for the rest of the climb. The summit was clearly visible from here in the conditions I had, but I think there were a couple of small waymarking cairns as far as I recall, for more inclement conditions. The view on the ascent opens up the whole of the northern section of the Nephin Begs, with Slieve Carr and Nephin Beg prominent in view, and Lough Feeagh and the undulating ridge walk from Ben Gorm to Corranabinnia off to the west. I completed the circuit to return via the West Top (551 mtrs) G 014 049 K and down the S-N ridge towards the Deel River (incidentally, the main salmon spawning stream for the mighty River Moy- most productive salmon river in Europe) and the farmstead over good firm ground. I should mention that after crossing the river and approaching the farm, I saw a notice on the gate which is clearly to deter unauthorised entry and with safety disclaimers etc. Fair enough. After some scanning around, I found that there was a stile in the fence running up the W side of the hill on the E side of the farm. Crossing the stile, there was an open gate across a small field, and then it was just a case of walking across to the river where it met the public track and crossing a wooden gate cum stile after negotiating the river. It is then just a walk down the public road to the start point. In summary, I would call this route a thoroughly enjoyable introduction to the Nephin Begs with no great access problems, and not too long an undertaking of 5-6 hours at a comfortable pace, but with still a sense of the vast openness of this beautiful mountain range.
