Weatherman Derek Brockway is in the South Wales valleys walking from Wales's highest town, Brynmawr, to the pretty market town of Abergavenny about nine miles away.

On the way he meets celebrity artist Nathan Wyburn and becomes friendly with some rare breed pigs. Wildlife expert and action girl, Lizzie Daly, goes paragliding over the Blorenge mountain and Matthew Bassett learns about an community enterprise which produced streamline furniture and fed families

Derek-the-Weather visits the stunning village of Beddgelert in Snowdonia to walk a 6-mile circular route with awe-inspiring views. On his way he visits a copper mine; helps National Trust volunteers build a footpath and learns the heroic – but fanciful – story of a hound that gave the village its name. Meanwhile wildlife expert Lizzie Daly gets up early to photograph mountain goats and Onkar Singh Purewal lends a hand to top off a slate sculpture, inspired by the landscape.
