Paro International Airport

Bhutan's sole international airport (IATA: PBH), situated at 2,235 m elevation in a deep valley of the Paro Chhu river, surrounded by peaks reaching 5,500 m. Considered one of the world's most challenging commercial airports, it requires pilots to hold a special qualification to navigate the steep, winding visual approach — only a handful of pilots worldwide are certified to land here. The single runway serves Druk Air and Bhutan Airlines with flights to destinations across India, Nepal, Bangladesh, Thailand, and Singapore.
