5Narsarsuaq Airport

There are multiple reasons why this airport in the southern part of Greenland is scary.

It’s situated amid Fjords—great for a picture but not so perfect for planes. The approach to the 6,000-foot runway through fjords is tricky and pilots need to make a 90-degree turn, which can be challenging due to strong winds. Then there are nearby volcanoes that erupt ash and reduce visibility.
