Absolutely not! You cannot obtain an entry visa to Bhutan unless you have pre-arranged a land tour itinerary with a licensed and approved tour operator, and have paid the requisite nightly all-inclusive government tariff. The Bhutanese government restricts independent visitors to uphold its stringent cultural and ecological values. However, once in Bhutan, you can still enjoy a considerable degree of flexibility during hikes, visits to local markets and villages, and interactions with locals. You have the option to arrange your own private tour without joining a group, but it must be prepaid and pre-arranged.
