A mostly level walk with one longish easy incline. Starting from Bwlchgwyn Aircrew Memorial through Black Wood and Nant Wood following the River Nant y Ffrith to Ffrith Railway Viaduct, returning to Bwlchgwyn, partly along an old packhorse trail.
There may or may not be Forest Operations in the woods and the re-stoning of the woodland track may or may not have been completed, but it is still passable. Some walking on quiet lanes and there may be mud. No cows/horses on the day of the reccy. Coffee at the Memorial before we set off and then a lunch stop.
