Overview

On the slopes of Carreg Goch, in the centre of The Black Mountain, lies the wreckage of Wellington Bomber MF509. A memorial close by commemorates the 6 Canadian crew who perished in the crash on the night of 20 November 1944.

We will climb steeply above the valley of Craig-y-Nos initially to find the Saith Maen line of neolithic standing stones, before traversing rough ground between tarns to the crash site.  Continuing, we pick up the Old Coffin Route that leads us through the hills back to our start.

Coffee and cake at the country park café after.
