Derek Brockway explores some of the less familiar stretches of the Welsh coastline. This episode sees him in the dramatic landscape of the north Gower saltmarshes, where he learns of the magical and mystical fairy folk, helps a sheep farmer round up his flock, and even has a go at weaving. Meanwhile, marine biologist Lizzie Daly is tracking trout and Matt Bassett rides the waves on a new ‘adaptive’ surfboard at Caswell Bay.
