26. Courcheval Altiport, France
The airport for the daredevils, this runway lies in the heart of the Alps, and is one of the most dangerous runways to land because of its short length and a gradient of 18.6%. But if you get over the terror of landing here, the approach shows the sun glinting off the snow capped peaks. Only specially qualified pilots are allowed to operate flights here and the flights are small with seating capacity of not more than 50.
