The adventurer has ditched the celebs and is back doing what he does best in his new series where he heads out on a journey of discovery across England, Scotland and Wales to experience the British Isles at their most spectacular. He begins with a trek around Snowdonia, a landscape shaped by volcanic eruptions and continental fractures. He then takes a fast boat crossing Cardigan Bay, which at 50-miles wide is the largest bay in Wales. He also learns more about Britain's smallest bat, and searches for an eco-system hidden in the depths of the North Wales countryside. He's some man though, all the same.
