Weatherman Walking

Derek Brockway returns with a new series of rambles around Wales. Tonight he heads to mid-Wales and the spectacular scenery of Devil's Bridge and the Rheidol valley. He's joined by Lisa Jenkins, who trained here for a walk to Everest base camp, and she puts Derek through some punishing hill climbs. For the second walk Derek goes south to Margam Castle near Port Talbot. Showing him round is James Cowan, who has a special interest in the supernatural tales connected to the castle.

This week Derek Brockway takes a walk with a difference, his partners are a pair of llamas! Together they explore the beautiful Berwyn Mountains in north east Wales. Derek also visits Tenby, leaving the tourist hotspots behind to discover more about the town's hidden past.

This week, Wales's favourite weatherman Derek Brockway is out walking at opposite ends of the country. First, he's high in the wilds of Snowdonia with disabled rambler Terry Taylor as they explore an old Roman road leading across the Carneddau Mountains. Later, Derek goes south to Skomer Island off Pembrokeshire. Guided by the warden Bee Buche, Derek gets a close-up view of the puffin population before staying up late to see the reclusive Manx shearwater.

This week, Derek Brockway's walks are full of history and amazing building feats. First he's on the banks of the Menai Strait walking between two brilliant bridges, the Britannia Bridge and the Menai Suspension Bridge. His guides are local WI members, and it was on Anglesey that Britain's first ever WI meeting was held over 100 years ago. Later, Derek treks between two captivating castles, at Caerphilly and Castell Coch, and even gets a chance to dress up as a medieval knight.
