Weatherman Walking: Prestatyn and Newport

Derek finds hidden treasures at opposite ends of Wales and discovers his artistic side. Both walks show the amazing places tucked just a stone's throw from busy Welsh towns. Singer Mike Peters from The Alarm is Derek's guide in the hills above Prestatyn - guitar in hand. In Newport, Joseph Anthony Connor, a mobile digital artist, is Derek's guide. Derek finds that a smart phone or a tablet can take the place of easel and paints. But how will his picture turn out? A beautiful walk along a canal with 14 locks - but soon the weatherman finds himself sheltering from a monsoon under the M4.
