Can I travel on my own without booking the trip with travel agent in advance?

All tourists to Bhutan must travel in a pre-booked tour package. It is not to censor your movement but to manage tourism in a sustainable way, to grow sensibly without taxing on the environment and its rich and intact culture. Having paid for a package tour, you can be flexible in the tour program, change the tour to see or do what interests you most and see as much to an extent feasible.
