Weatherman Derek Brockway's walk in Cardigan Bay has something for everyone. For the first half, he explores one of Britain's oldest and largest raised bogs. His route then takes him to a unique railway museum filled with nostalgia, and he also discovers the legend of Cantre's Gwaelod at Sarn Cynfelyna, which stretches an incredible 11 kms out to sea. He finishes at the university town of Aberystwyth with its Victorian cliff-top pleasure park. Derek also has a go at paddling-boarding - which has its challenges.

Derek Brockway is in Pembrokeshire with its majestic cliffs, feeling what it is like to be exposed to the elements. He is thrilled to peek at seal pups along the way, learns how to train a sheepdog, builds a stone wall and helps to create a unique sand circle.
