Obviously, I won’t miss that. The most famous thing to do in Vang Vieng when you are young and crazy !
So what is this concept ?
People are coming here to float along the river in an inflatable rubber ring. And on the coast, you kind find a lot of outdoor bars where you can drink A LOT. They have these concept of buckets, same than in the Thaï islands, which is very nice.
They have also some attractions in the trees where you can bounce on the rope such as Tarzan, use some homemade tyrollean, swings and so on.
The only thing is that it might be dangerous as there are some rocks in the rivers and you need to be careful where you land. Vang Vieng is well known for the numerous accidents caused by these attractions with people too drunk.
But a part from that, it is very good and it is a good way to meet new people.
Just have a look at this video and you will understand why this experience is a must do.
