Vang Vieng Warnings and Dangers: 14 reviews and 11 photos
Don't want to discourage you from both but it's worth warning: deaths have already been reported of few people who got drunk (or stoned) and drowned when tubing in Vang Vieng. It can be so delusing: waters of Song river are rather lazy, not often with rapids and in certain parts deep. It is safer you take tuk-tuk back to your guesthouse when you're not clear in your mind than going to tubing. You can still do it next day.
Now most of bars by river and all of them in island have been closed since a few years ago.
The choice is yours but be sure of what you're doing and don't take playing with water so innocent. That's one of the dark sides of fun tourism in VV.
