1x2 - Britain's Biggest Adventures with Bear Grylls

The adventurer continues to explore the UK's natural history, abseiling at Malham Cove in the Yorkshire Dales and getting into danger in a flooding cave. Malham has long attracted tourists and geologists alike to wonder at its beauty and history, as well as walkers attracted to the limestone formation and its surrounding pathways, and Bear reveals a tropical past to one of North Yorkshire's finest features.
