Bhutan

Known for its landscapes and ancient Buddhist monasteries, Bhutan is an emerging destination on many savvy travelers' radars. It's no easy feat getting to the country, but dedicated travelers will be rewarded with incomparable Himalayan scenery and a spiritually rich culture that is both enigmatic and endearing.

Bhutan has one international airport in Paro, which is often ranked as one of the most dangerous airports in the world, thanks to its location in the middle of a steep, narrow valley.

Bhutan's two national airlines (Drukair and Bhutan Airlines) are the only air carriers permitted to transport international travelers in and out of the country. Direct flights to Paro are only available from a handful of Asian cities, including Bangkok, Delhi and Singapore.

All visitors must book their trip through a Bhutanese tour operator, which handles all mandatory visa arrangements, but costs a minimum of $250 per day.

So what makes Bhutan worth all the pre-arrival trouble? Travelers say Paro Taktsang alone is worth the hassle. Known as the Tiger's Nest, Paro Taktsang is a 17th-century Buddhist monastery that sits precariously on the edge of a cliff, overlooking the upper Paro Valley.

For adventure enthusiasts, Bhutan's Himalayan treks are unparalleled. Lodging options across Bhutan range from budget-friendly to luxurious.
