There are only two of ways to enter Bhutan. One is by taking a flight directly to Paro, which is what all the international tourists do. And the other is by road through the border town of
Phuntsholing. Independant travel is discouraged in Bhutan and traveling inside the country is expensive for most tourists. They have to cough up close to 250$ per day for the pleasure of visiting the country, so you dont  get to see independant backpackers there.Â
This article is mostly intended for the tourists from the Indian sub-continent for whom the above restrictions don't apply. There are however a few permits to be obtained after which they are free to travel on their own within this magnificent country.Â
