Xingyi Wanfenglin Airport — Xingyi, China

Xingyi Wanfenglin Airport, in China's mountainous Guizhou Province, keeps its single runway at a high 4,150 feet above sea level, set on the karst plateau terrain that defines much of southwestern Guizhou. Xingyi sits close to where Guizhou, Yunnan, and Guangxi meet, in one of China's less-visited interior provinces compared with its major coastal cities. The field spares travelers the winding mountain roads that would otherwise make the trip to larger Chinese cities considerably longer and slower across this rugged terrain.
