Transport in Bhutan uses about 8,000 kilometres (5,000 mi) of roads and four airports, three of which are operational and interconnected. Paro Airport is the only airport which accommodates international flights. As part of Bhutan's infrastructure modernization programs, its road system has been under development since the 1960s. There are no railways, and as Bhutan is a landlocked country with no major waterways, there are no ports.

Paro International Airport is the sole international airport of the four airports in Bhutan. It is 6 kilometres from Paro in a deep valley on the bank of the river Paro Chhu. With surrounding peaks as high as 5,500 metres (18,000 ft), it is considered one of the world's most challenging airports, and only a very small number of pilots are certified to land at the airport.
