Derek heads off on two contrasting walks - one in rural Radnorshire and the other along the clifftop footpaths and beautiful bays of Anglesey's far north coast.
In the middle of Wales, the first walk takes Derek on a nine-mile loop, starting and ending in the market town of Rhayader and taking in the Gilfach Nature Reserve along the way. He then heads along Anglesey's costal path from Wylfa, through the harbour town of Cemaes Bay to Porthwen.
