Paro Airport, Bhutan

Only eight pilots worldwide are certified to land here, threading between 18,000-foot Himalayan peaks through a valley so narrow that solely visual approaches are permitted. Since 2008, there have been zero fatal accidents here—a testament to the stringent certification, though 15% of flights are aborted due to unsafe weather. This exclusive pilot group, requiring over 500 hours of specialized training, makes Paro a terrifying yet meticulously controlled experience.
