Getting In Bhutan
The best way to enter Bhutan is by Druk Air, the national air carrier. Druk Air is the only airline operating in Bhutan. You can connect to Bhutan on Druk Air from Delhi, Calcutta, Kathmandu, Bangkok and Dhaka.
You may also enter/exit Bhutan from Phuntsholing, a southern Bhutanese border town located four hours’ drive from Bagdogra, India. Travellers who wish to visit Sikkim, West Bengal and Bhutan, Phuntsholing is a convenient spot.
