Bhutan may be small on the world map but it’s really big if the only means of transportation is by car. There is no trains nor domestic airports yet. I think that it’s nice to stay that way even though it takes a bit more time commuting. More vehicles, tracks and airports means more pollution.
So you will spend quite a lot of time sitting in a car, particularly if you travel to the central Bhutan. At the moment, there is only one highway connecting the west the east. There is a road widening project going on right now that makes the road bumpy and some times rock falls and mud slides, making the commute more challenging. It is more challenging in the summer when it rains a lot.
Having said that, it’s not all that boring on a long car ride. Bhutan is a lush country with a lot of trees and valleys. It’s beautiful everywhere and you will often see some yaks and cows herding along the road. Anther interesting thing is this type of trucks. Local people call it “potato truck” because Bhutan produces a lot of potatoes which are sold to India. The trucks are very charming, with paintings everywhere.
