"Ellie Harrison and John Craven are in the beautiful Wye Valley on the border of England and South Wales.
Ellie faces her fear as she scales a sheer rock pinnacle called the Longstone, before zipping along a wire high above the ground in a risky manoeuvre called a Tyrolean Traverse. John is going back in time to take a look at how the 12th Century monks of Tintern Abbey once lived and worked this landscape. He will also be learning all about their relationship with agriculture, living off the land and their penchant for a rather unusual but increasingly more common tipple."
