The comforting voice of Charles Hawes, who is a walking blogger, a very experienced long-distance

Park, because in this series of ramblings, we've decided to take on the challenge of walking every day so yesterday I did the first section of the Dales way you heard it in the programme last week and we started to Viltley and walked to Bolton Abbey and finished at just before Bolton Priory this fantastic ruined medieval priory and now we're at the other edge the western side of before Bolton Priory, this fantastic ruined medieval priory.

And now we're at the other edge, the western side of the Bolton Estate,

starting at Cavendish Pavilion, which is a lovely Victorian-looking cafe.
