Paro Airport is the sole international airport of the four airports in the Kingdom of Bhutan. It is 6 km (3.7 mi; 3.2 nmi) from Paro in a deep valley on the bank of the river Paro Chhu. With surrounding peaks as high as 5,500 m (18,000 ft), it is considered one of the world's most challenging airports, as a select number of pilots are certified to land at the airport.
Located in the Himalayas, it offers a view of small houses scattered around the foothills. Though landing is considered to be tough here, the views over the clear blue waters over the Paro river and the lush green surroundings take the edge off passengers' nerves.
