Story by theus from Amsterdam, The Netherlands, submitted on 29/08/2014
From Lanslebourg, one of the most beautiful climbs in the Alps (world?). After a few hard kilometres to start with, you''ll have an easy road to Bonneval. Here, the real climb and the real scenery of the Parc National de Vanoise starts. Exceptional, Lord of the Rings could have been shot here!
