Bhutan prices tourism per person, per night, with a fixed minimum package. Here's exactly what that covers.
All internal taxes and charges, and a Sustainable Development Fee of USD $65 per person, per night. This fee directly funds free education, free healthcare, poverty alleviation and infrastructure across Bhutan.
Rates above come directly from the old site and should be re-verified against the current Tourism Council of Bhutan schedule before publishing — Bhutan's tourism levy structure has changed more than once in recent years.
