The Kingdom of Bhutan is a tiny landlocked mountainous country in South Asia, located in the eastern Himalayas mountain range between Tibet (China) in the north and India in the East, West and South. You can visit Bhutan either by air or by road, just depending on your choice.
By road: The only way is from India because the border with Tibet (China) is completely closed. Phuentsholing (Chukha district, western Bhutan) adjoining Jaigaon (Alipurduar district, West Bengal), Gelephu (Sarpang district, central Bhutan) adjoining Dadgiri (Chirang district, Assam), Samtse (Samtse district, western Bhutan) adjoining Chamurchi (Jalpaiguri district, West Bengal) and Samdrup Jongkhar (Samdrup Jongkhar district, eastern Bhutan) adjoining Mella Bazaar (NK Darrang, Assam) are only land border areas that open to tourists. As of now, only Indian tourists can enter Bhutan via land entry points (Gelephu, Samdrup Jongkhar, and Samtse).
By air: There are two airlines in Bhutan. They are Druk Air (The National Airline of the Kingdom of Bhutan) and Bhutan Airlines. There is only a solely Paro international airport in Bhutan. Druk Air connects Paro with Bagdogra, Kolkata, Delhi, Gaya, Guwahati of India, Dhaka (Bangladesh), Kathmandu (Nepal), Bangkok (Thailand), Dubai (United Arab Emirates) and Singapore. Bhutan Airlines connects Paro with Delhi, Kolkota, Mumbai, Bangalore, Gaya, Kathmandu, Sharjah (United Arab Emirates), Ho Chi Minh (Vietnam), and Bangkok. Their flight schedule is changed by season, but usually there are several flights per week from Kathmandu, Delhi, Dhaka,
Kolkata, Sharjah, and Singapore. Only flight from Bangkok to Paro is every day. Bookings are
made through your travel agent or online. Airport departure tax is included in air fare.
You should check your passport’s validity as it is required to remain valid for at least six months at the time of departure and two blank pages to issue the visa/ travel permit. In addition to that, all tourists (excluding tourists from India) visiting Bhutan must have a e- visa issued by the Department of Immigration of Bhutan prior to boarding of the flight. Indian tourists need an e- travel permit. You will be asked to show your e- visa/ e- travel permit at the time of check-in or otherwise, will be denied at the check-in counter. Note that Druk Air and Bhutan airlines will not be liable for any claims arising thereto.
