An early off-road guide book based on OS maps - forgotten the name - recommended a classic route on bridleways to the east of the above track. From Bugeilyn boat house to the derelict farmhouse at Maesnant, emerging on the east side of Nant-y-Moch, it was something of a nightmare, with bogs and a risky stream crossing. I was glad to get out. But it was as wild as you could get.
