Clare Balding's river adventures continue in the north of England, exploring the mighty River Tyne, following it from the vibrant city of Newcastle, past beautiful towns and villages, remarkable Roman ruins and riverside retreats, into Northumberland towards its source. Among the sights and stops: the iconic Tyne bridge; the historic riverside town of Wylam; fly fishing Series at Watersmeet; and Kielder Reservoir, northern Europe's largest manmade lake.
