Weatherman Walking S11E01 - Dinefwr Park and Sully

Derek's back! With 8 more incredible walks around Wales. He's on ranger duties at a country estate in Carmarthenshire, exploring Dinefwr Park's 800 acres of magical medieval landscape and getting up close and personal with a very rare cattle breed! In the Vale of Glamorgan, Derek's joined by one of the nation's favourite Olympians, Colin Jackson. Together they're exploring a 5 mile coastal route that has it all...Dinosaur footprints, WW2 gun battery remains, the site of a major communication breakthrough AND an iconic Victorian pier.
