The Call Of The Wild

Little more than 100 years ago, Scottish mountains standing at more than 3,000 feet were virtually unknown. Today they are familiar terrain to many thousands of climbers, thanks to Victorian adventurer Hugh Munro's determination to list the high peaks which now define the highlands and islands of Scotland. This documentary tells the story of the magnificent peaks that bear his name and the people who have been possessed by them. The birth of this obsession - now known as Munrobagging - is a twisting tale of intrigue, which presenter Nicholas Crane unravels high on the ridges and pinnacles of some of Scotland's most spectacular mountains.
