Paro International Airport, Paro, Bhutan

If you want to visit Bhutan, chances are you'll have to fly into Paro, the only international airport in the country. "Anywhere where there's mountainous terrain there's a challenge," says Captain Sitarz. And Paro is no exception. Soaring through 16,000-foot Himalayan Mountains with whipping winds gets your adrenaline pumping as you approach the 6,050-foot runway, located in a deep, tree-lined valley. According to the website of Drukair, the only airline serving Paro, "each flight is a mesmerizing aeronautical feat and offers an exciting descent into the kingdom." But fear not: Pilots are specially trained to fly into Bhutan, and accessing the airport is entirely dependent on good weather conditions.
