The World's Scariest Runways

Tenzing-Hillary Airport
Lukla, Nepal

Who Flies There: Yeti Airlines

Why It’s Harrowing: Recently renamed after the famous Everest climber-conquerers, mountainous Tenzing-Hillary Airport not only has one of the steepest uphill runways in the world, but its drop-off, into the wind shear-prone Himalayan valley below, is sure to give even the heartiest mountaineers pause. Here, daily 30-minute flights from Katmandu are only allowed to land during daylight, weather permitting.
