As I started out, mist was descending from the south over the col between Bautregaum and Caherconree down into Derrymore Glen. Baurtregaum NW was coming in and out of view.
I followed the rocky track into Derrymore Glen (along the west side of the river) from the Dingle Way to the North. Kept going south until almost reaching the largest lake towards the head of the glen where it is easy to step across the multiple shallow, narrow streams and head north-eastwards to reach this subsidiary top.
Crossing the streams further north would be more difficult as they have cut ravines and there is a deep cutting stream flowing out of the col between this top and the Scragg spur to the north east.
Upon reaching BNW, having completed my sole objective on this evening outing and with thick mist above the 700 metre mark I had the choice of retracing my steps back to the beautiful glen or finding a route back down to the north.
Reaching for Adrian Hendroff's book on Dingle I noted his suggestion of heading north east to point 657, marked as Scragg on the OS (a nice viewpoint in its own right), then north/north west down the steep slope of Scragg. With hindsight, I really don't think this is a good way down. As Hendroff notes (though I would rather caution), the lower reaches of the northern slope of Scragg, (as is the case seemingly pretty much with the lower northern reaches of all the Slieve Mish), are heavily cloaked in very deep heather, grass, and worse still, bracken. It is quite difficult to safely make your way down as the high bracken in particular conceals a multitude of ankle snaring hollows, rocks and crevices. At the very least, this should not be attempted without sticks. I was very happy to have exited this "wouldn't wish on my worst enemy" purgatory and safely find my way back to the Dingle Way.
That said, the glen itself is a marvellous place to visit, so if I had my time again, I might have tried to get back down the steep slope towards the larger lake and enjoy the views of the cascading streams down the walls of the glen in the swirling mist.
