Bhutan remained largely isolated from the rest of the world up until the early 1960’s. Entering the country was difficult as it was only accessible by foot from two main entry points, one in the North and another from the South. The Northern route was through Tibet, crossing high mountain passes that were inaccessible due to the snowfall and severe winter. The second entry route from the South came through the plains of Assam and West Bengal. The high, frozen passes in the North and the dense, jungles in the South made it extremely difficult to enter the country.
However, with the visit of honorable Prime Minister Mr. Nehru the construction of motor able roads came to picture. With the immense support from the Indian Government and carefully planned economic development has made the country much more convenient to travel. Today the main roads entering the country are through Phuentsholing in the south, linking Bhutan with the Indian plains of West Bengal, through the border towns of Gelephu, in the central region and Samdrup Jongkhar, in the east, that link with the Indian state of Assam.
Bhutan does not have a well-developed public transport system, so you will largely have to rely on tourist vehicles hired from Thimpu or Paro for the duration of your trip.
