Vang Vieng is a small town, located around 2 hours north of the capital of Laos, Vientiane. It's surrounded by picturesque, green mountains and The Nam Song River, which slowly flows through the town.
Floating on a huge tube down the river, was (and still is) one of the things to do when you're in Vang Vieng. The waters here are shallow and slow enough to provide you with a very relaxing experience.
Hot air balloons do their flights every afternoon until sunset. They look so pretty in a cloudless, blue sky. One flight costs around $80.
