The third of three, Blue Lagoon 3 is an hour away from Vang Vieng and so the farthest. However, there are ziplines, swings, balancing beams and bamboo rafts for you to play with, and the water is shaded by the mountains nearby. As such, the water is refreshingly cool. Despite the entry fee, which is also 10,000 kip (US$1.50), and the distance, Blue Lagoon 3 is the local favourite.
