Until 1960, it was too difficult to enter into the Kingdom of Bhutan. The dense jungles in the South and high frozen passes in the North made the entry extremely difficult. However, now it is much more accessible through many international and multiple domestic airports due to planned economic development.
Bhutan can be easily reached by air, train and road from various countries. Many countries have direct flights to Bhutan. By land, there are two entry roads through Phuentsholing and Gelephu, linking with the Indian states of West Bengal and Assam respectively. Read here about How to Reach Bhutan easily :
