It is impossible to predict the flight time to Bhutan from the US, as there are no connecting flights available. First, you must travel to a nation that offers flights to Bhutan in the first place – India is one of the most common, but you can also reach Bhutan from Thailand (Bangkok International Airport). Bangkok offers direct flights to Bhutan and it takes about 2h to make the flight to Paro. You will usually land at Paro International airport, which is the primary point of entry for international travelers. It is located just a few miles from the city of Paro, and flying into the airport is an interesting experience, as you get closer to the mountaintops than with almost any other destination in the world.
There are no direct flights from the US to Bhutan and no connecting flights are possible, either. In order to reach this mountainous nation, you will need to first decide which country you want to visit that is served by Bhutan Airlines, as this is the only way into the country. Flights to Bhutan can be arranged from Bangkok, as mentioned, but also from Kolkata and Delhi. Flight times vary depending on your point of origin, but range from 2h – 3h 20m. This does not include the flight time from the US to your second destination city, which can take 24h or more depending on your point of origin and the number of stopovers on your flight.
Reaching Bhutan from the US is no easy feat, but getting around the country is simpler. You will find plenty of taxis on offer in Paro, as well as in cities like Jakar and Thimphu. Unlike cities in some other nations, Bhutanese use meters, but they are not always used, so make sure you get a price before you set off. Note that there are no railways in this nation, and there is only a single main road, called the National Highway, which at present is a combination of one and two-lane roadways. Car rental is not an option in Bhutan and you will need to hire a tour operator to provide road transportation to wherever you intend to go. There are options for air travel, though, as the nation has several domestic airports, although flights are often limited.
While Bhutan might be small and relatively inaccessible, there are things you can find to enjoy here. One of the most popular options is to visit Buddha Dordenma, which is a stunning, tall Buddha statue. Khamsum Yulley Namgyal Chorten and Punakha Dzong are also popular destinations. If the weather is good, it is worth traveling through Dochula Pass for the stunning scenery. Chele La Pass is also an interesting place to visit. Finally, you may also like to visit the Tango Buddhist Institute for architecture.
Yes, you will need a passport to enter Bhutan as a US citizen. You will need one blank page and at least six months of validity remaining. You will also need to pay for a tourist visa before you can enter the country, and vaccinations are suggested by not required.
