Passing through Italy, France and Switzerland and circling the mighty peak that is Mont Blanc, the aptly named Tour Mont Blanc is one of the world's great walks. Passing scenes capable of inducing wobbly knees, a mix alpine cottages, glacial remains, snow capped mountains and valleys that stretch into eternity, the walk, which takes a week to complete, is for those predisposed to wanderlust. Aided by a mule called Coco and fuelled by a diet of bread and cheese (the wine would prove too heavy to carry), my own venture around the mountain has been etched into my memory - the thick forests, mirror-like lakes and towns abandoned by time are not something you ever really forget.
