Foel Goch is a stand alone Nuttall that sits just outside Snowdonia National Park near Bala but is still in the Arenig mountain range. Follow this link for my route to the summit.
Basically followed the Nuttalls route up and back. Unlike them I had no difficulty keeping to the path all the way. It is very evident on the ground as long as you watch whete you sre going. Great viewpoint.
