Plans redrawn from Jones, K. (1992) The Caves and Mines of the Sychrhyd Gorge

Will’s Hole cave lies under Craig-y-Ddinas (Dinas Rock) in Pont-Nedd-Fechan near Rhigos.
A Welsh legend claims that King Arthur and his knights lie asleep under
this rock and they will arise again
when Wales is in danger, and a famous Welsh folk tale is the story of
the
treasure of Craig-y-Ddinas.
We used to explore these caves with these stories fresh in our minds.
