Tham Nam (Water Cave)
Vang Vieng has traditionally been renowned as a dreamland for hiking, trekking, climbing, swimming, and tubing because of the abundance of natural areas in the area. Tham Nam is the one that stands out the most from the rest on the list. The name "Nam Tham" translates to "Water Cave," and while this cave is just approximately 500 meters long, it offers a lot of entertainment.
It begins at Nam Song's tributary and ends at the low entrance. During the rainy season, when the water level rises significantly, tourists can go tubing inside the cave and drag a guide line to go in and out. With a headlamp, you can appreciate the cave's splendor while having a great time. In the dry season, on the other hand, you can wade inside the cave and perhaps have a brief water fight!
