Getting from Kathmandu airport to the city center

Fastest options: prepaid taxi or hotel transfer. Best value: local bus or shared microbus.

Kathmandu is served by Tribhuvan International Airport (KTM), Nepal's only international airport, located approximately 6 km east of the city center. Despite the short distance, airport transfers to city center destinations can take 20 to 60 minutes depending on traffic conditions, which are notoriously congested in the Kathmandu Valley. Transport options include prepaid taxis, metered taxis, hotel shuttles, ride-hailing services, local buses, and private transfers. The airport has a dedicated prepaid taxi counter inside the arrivals hall, which is the recommended option for first-time visitors.
