Courchevel Altiport, France

Courchevel Altiport’s 525-meter runway, inclined at 18.5%, demands 30% more precision than the typical alpine airfield, making it the scariest in France. Pilots rely solely on visual cues for a near-vertical descent in a single direction, with no instrument approaches available. Featured in a James Bond film, this runway forces pilots to abort 40% of landing attempts annually despite 6 months of training by Air France. Its sheer cliff drop-off adds a permanent risk of catastrophic error, surpassing #7 Gibraltar’s highway crossing in sheer nerve.
