Iolo Williams explores the Brecon Beacons over a period of one whole year. It’s a stunning national park covering an area of over 500 square miles in south Wales. Four 30 minute episodes covering the four seasons were produced for BBC Wales
Iolo Williams ends his journey in the autumn. It’s a time when the National Park is at its colourful best. The fall sees thousands of fieldfares arriving from Europe who are escaping from the colder continent to the relatively less severe climate of Wales. In a water mill in the Usk Valley, bats feed up for the last few nights before they disappear to hibernate in caves. Water birds are also arriving on Talybont Reservoir ready for winter. Iolo looks for cave spiders and discovers hundreds of sea trout migrate upstream to the Carmarthenshire uplands.
