There are 2 ways through which you can enter Bhutan:
The best way to enter Bhutan is by Druk Air, the national air carrier. The following cities are connected to Bhutan with Druk Air flights.
- India: Delhi (DEL), Kolkotta (CCU) & Gaya (GAY)
- Nepal: Kathmandu (KTM)
- Bangladesh: Dhaka (DAC)
- Thailand: Bangkok (BKK)
- Burma: Rangoon (RGN)
Druk Air is the only airline operating in Bhutan. As Druk Air flights may be delayed because of weather in the monsoon (July & August), it is advisable to keep a 24-hour gap before any onward international connections.
Bhutan Travelers can assist you in arranging your Druk Air flights. For the Druk Air reservation, we would require your full names as in your passports. We will buy your Druk Air tickets and send them to you in advance or to the respective Druk Air check-in counters from where you board your flights. You may collect them at the check-in counter on arrival.
There is one overland entry and 2 exit points:
Both entry and exit can be done via Phuntsholing
You can enter/exit Bhutan overland from the Indian state of West Bengal into Phuntsholing, border town in southwest of Bhutan. Four hours drive from Phuntsholing will take you to Bagdogra in the state of West Bengal (India) which is the nearest airport from Phuntsholing. Phuntsholing serves as a convenient point for the travelers wishing to visit the Indian states of Sikkim, West Bengal along with Bhutan. The drive from Phuntsholing to Thimphu takes six hours.
Only exit can be done via Samdrup Jongkhar
Samdrup Jongkhar is in southeast, 110 km from Guwahati, India, which is nearest to the Guwahati Airport. From Guwahati, you may fly into other Indian cities like Delhi, Bombay or Kolkotta and to your onward flight connections. This exit is more convenient if the travelers do not wish to travel back the same lateral route to Paro for the flights and who would like to combine Assam trips with Bhutan.
