River Tees

Kirsten O'Brien takes a 15-mile walk along the River Tees near Barnard Castle, exploring the history of Upper Teesdale. Kirsten meets some of extraordinary people who call its banks home and takes a wild swim in its white waters.

Kirsten begins her trek at South Gare near Redcar - a childhood playground for Kirsten and her brother - and then takes in High Force, Middleton in Teesdale and ancient Egglestone Abbey.

Along the way, she samples the local cheese, learns about the Dale's wildlife and meets an artist who specialises in canine portraits.
