Derek Brockway's in Flintshire, at the most northerly point of mainland Wales. He starts off at the site of the Point of Ayr Colliery, where he meets John Wiltshire, passionate about keeping the memory of the mine alive. Derek also lends a hand, helping endangered species in the sand dunes, and little terns who nest on the beach just over the Denbighshire border. In ‘Sunny Rhyl' he learns to kitesurf and do the surfers' shaka.

The final episode in the series and Derek Brockway is in the Vale of Glamorgan on a walk of contrasts. On his journey he takes part in a lifeboat challenge, walks a guide dog puppy, sledges down a spectacular sand dune, rides a horse on Ogmore beach and fishes off the rocks. He's also joined by a group of women walkers who end the series toasting marshmallows on the beach in the shadow of one of Wales' most stunning rock formations.
