Hi,
My personal favourite is "Clear Waters Rising" by Nicholas Crane, the story of one man's walk from Cape Finisterre to Istanbul =10,000km.
Nick decided to follow the mountain chains through Europe ie Santiago, Cantabrians, Pyrenees, Cevennes, Alps,Carpathians and finally the Balkan Mountains, all of this (largely) unaccompanied and just after getting married. He camped or lived with shepherds, cheesemakers etc. while making this non-stop journey.
A wonderful tale well told.
Brits may recognise Nick from his subsequent TV programmes 'Coast' and 'Map Man' and currently 'Great British Journeys' .
Enjoy
Dael
