With a few hours to spare on a trip to the Nephins I decided to try a walk N of Lough Nafooey. My plan was to follow the skyline above the Dooletter Valley taking in Skeltia on the ascent and Leynabricka on the descent. I parked the car at the carpark overlooking the lake (Ref: 983603 H) and headed up the hill. On reaching Skeltia my curiosity was aroused when looking at the map by the deep valley running SE from Mám Trasna summit, and from which the Srahnalong River flows. I headed E to have a look and once I had sight of this magnificant valley from above my route plan immediately changed. It is narrow, deep, with tumbling streams, and layer after layer of craggy edges running up the NE face of the valley. I decided I simply had to descend through this wonderful place. I first headed NW and then made my way into the head of the valley N of the major stream feeding the river below. The descent was steeper than it needed to be,as I made my way to the NE side of the valley to the foot of the craggy edges before dropping down to the river. Once the river was reached it was a pleasant walk out the valley. It was well worth it, and it reminded me of a scaled up craggy version of the Macha na Bo/Glennahoo valley E of Beenoskee on the Dingle Peninsula. Stay on the L bank as the land the right has been broken up with loads of fencing at right angles to the river. Returned to the car via the bog roads and col at Ref: L99111 60648 F and a heathery descent to the road (not recommended). Plan to return. Linkback: https://mountainviews.ie/summit/132/comment/1104/
