Bhutan’s tourism sector is closely monitored by the government. It is mandatory for all foreign tourists, with an exception to nationals of India, Bangladesh and Maldives, to book their tour through a tour operator. In simple words, travelers cannot simply book their flights to Bhutan and travel around on their own. On booking a guided package tour through an agent, your visa, hotel, transportation, guide, driver, etc will be arranged. Your visa will be given to your operator on full payment of the trip package cost. In a nut shell, you cannot travel to Bhutan independently and it is obligatory that you book your holiday with a registered tour operator.
