Travel to Bhutan is highly regulated in order to minimize the impact on the society and nature of Bhutan under the policy "High Value, Low Impact Tourism". It is a government regulation that foreign tourists must use a licensed Bhutanese tour operator or one of their international partners.
Citizens of all other nations must arrange visas in advance, which are stamped into passports on arrival upon presenting a visa clearance letter at the port of entry. Visas only issued when arriving on a pre-booked tour with (as of 2014) a fixed price of $200 per day in low season and $250 per day in high season. Discounts also apply for minors and larger groups while and surcharges exist for groups smaller than 3. The minimum daily package required for visa processing covers accommodation, food, guide and vehicle with driver. Part of it goes towards free education, free healthcare and poverty alleviation.
All visitors must hold a passport valid for 6 months.
