We can take a tour and visit some of these caves. The main reason why young people come to Vang Vieng is to go Inner Tubing. You basically rent a tube in town, they bring you upstream and you jump in your tube and follow the flow. There are several bars along the way where you can have a drink. Most bars have a swing from where you can jump in the water. The only thing people care about during tubing is having fun. You can also go down the river on a Kayak. West of Vang Vieng across the river you will find the Blue Lagoon. The Lagoon is great fun for swimming and you can also visit the cave that is nearby. You can reach the Blue Lagoon by bike. For those who like to walk, it is a 7 kilometers hike.
