Blue Lagoon
Blue Lagoon (Tham Phu Kham)
A clear, emerald pool about 7 km west of town. You can jump from a large tree, and a reclining Buddha sits inside the nearby Phu Kham Cave.
Blue Lagoon (Lagoon 1) lies about 7 km west of Vang Vieng town, near Nam Thong village. It is a pool formed where streams flowing from the foot of Phu Kham Mountain converge, with water that appears bright blue or jade-green and is crystal clear. A large tree by the pool offers jumping platforms at different heights, and you can swing on a rope into the water or simply sit on the wooden platforms to sunbathe and eat grilled snacks. Bamboo rafts, swings, and food stalls are nearby. Behind the pool, a steep stone staircase climbs about 15 minutes to Phu Kham Cave. Inside, the cave is spacious, with a bronze reclining Buddha among the stalactites. Sunlight streaming through the entrance forms light beams. A headlamp is recommended for exploring deeper into the cave. Admission is a small amount of kip. Because Lagoon 1 is crowded, Lagoon 2 and Lagoon 3, farther on, offer a more natural setting.
Getting there: Rent a motorbike, bicycle, or 4WD in town and drive west on the dirt road, crossing the toll bridge over the Nam Song. It takes 20 to 30 minutes. You can also charter a tuk-tuk.
Tips: Check the water depth before jumping, and wear a life jacket if you cannot swim. The road is muddy during the rainy season.
