Bwlch and Glyders

Derek tackles two of our well-loved mountain ranges - the Black Mountains in the Brecon Beacons and the Glyders in Snowdonia. Starting in the small village of Bwlch, his walk explores the history of the Rhiangoll Valley and the village of Cwmdu, before hitting the hills to follow the Beacons Way, up and over and back to Bwlch. His next challenge is to climb one of Wales' super-mountains - Glyder Fawr at over 3200ft! It's tough going, with scrambling and thick fog - will he get to the top?
