The following are certain things that you have to keep in mind while traveling to Bhutan, which I came to know after my recent trip to Bhutan. I thought of writing about them here so that it is useful for others who are also planning for a trip there.
There are two ways to get inside Bhutan. One is to enter via Phuentsholing and the second option is to fly up till Paro and land there. To come out of Bhutan you can use the above two routes or come out through Samdrup as well. But you can’t enter through Samdrup.
For Indians you don’t need a get a visa in advance to enter Bhutan. You can get the permit on arrival, either at Phuentsholing or at Paro. You will initially get a permit for 7 days at Phuentsholing and using it you can visit only Thimphu and Paro. To stay more or visit other restricted places which I visited like Haa valley, Punakha or Bumthang, you need to renew your permit in Thimphu. The immigration office is located at Norzin Lam in Thimphu.
Bhutan follows a different timezone than India. It is GMT + 6 hours, which is 30 minutes ahead of Indian standard time. Once you cross Phuentsholing all times which are displayed are in Bhutan timezone. We missed our bus to Thimphu from Phuentsholing because of this timezone difference.
