Derek Brockway is 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 is joined by one of the nation’s favourite Olympians, Colin Jackson. Together, they explore a five-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. Show less
