In reply to Welsh Kate:
I see what you mean about #10. I think there are sections of the route that are mandatory to avoid sensitive areas. Not sure if that section is though... having said that, that's the way I would go as far as the top of Cwm Moch. From then on I'd stick to the ridge. Off-piste in the Rhinogydd isn't much fun! 😮
