For many centuries, Bhutan was isolated from the rest of the world. It was only in the 1960s that Bhutan first became connected to India by highway from Thimphu. Then in the 1980s, the first flights from India began arriving in Paro. The infrastructure of Bhutan has improved much over the last several decades. There is now a network of roads entering and traversing the country, as well as one international and multiple domestic airports within the country. Because of its remoteness, Bhutan has no port or railway system.
Paro is the only international airport in Bhutan. Currently, there are only two airlines that fly into Bhutan. You must book your flight with either Druk Air or Bhutan Airlines.
- Druk Air offers more international and domestic routes for travelers. It operates daily flights from Bangkok (Thailand). It also flies two or three times per week from Dacca (Bangladesh), Kolkata, Bagdogra, Delhi, Bodh Gaya, Guwahati, Mumbai in India, Kathmandu in Nepal, and Singapore. (Please check the Druk Air website for the latest schedule).
- Bhutan Airlines offers daily flights from Bangkok to Paro via Kolkata, India, and three flights a week to Delhi via Kathmandu.
There is three port of entry and exit while traveling overland.
- Phuentsholing, (border southwest commercial town), roads, and railways networks are well established with other popular tourist destination namely Darjeeling, Kalimpong & Indian state of Sikkim and the rest of India. And it’s merely 4 hours drive to Bagdogra (nearest Indian airport). Jaigoan is the Indian border town where you have to exit an Indian visa to enter Bhutan and vice versa.
- Samdrup Jongkhar (far south east town). It shares its border with the Indian state of Assam. The nearest Indian Airport is at Guwahati, which takes approx 3 hours to reach Samdrup Jongkhar. It adjoins a small Indian border town called Daranga, which harbors Indian Immigration Checkpost for related Indian visa work.
