Located at the midpoint between Vientiane and Luang Prabang, the town of Vang Vieng is popular with backpackers for its adventure sports and scenic limestone mountains along the Nam Song River. You can rent a motorbike to explore the countryside and be met with tropical forests, rice paddy fields, and local villages, and blue lagoons. Hidden behind the green is the Kaeng Nyui waterfall, to which you can get by following a dreamy jungle trail. Immersing yourself in the crystal-clear, turquoise water of the Blue Lagoons is the best way to relax in Vang Vieng. The Nam Xay viewpoint, which takes about 30 minutes of hiking, gives you panoramic views of the town. You can also visit the Tham Chang Cave, a natural Buddhist sanctuary to make the most out of your trip here.
