Blue Lagoon 3

Top choice Swimming

in Vang Vieng

Forget the circus that is the original Blue Lagoon (Tham Phu Kham) and head 14km further west to the Blue Lagoon 3. The azure waters are fed by a natural spring that emerges from a nearby karst limestone peak and it is still relatively quiet compared with its more infamous namesake.

Tubes are available for hire, and there is a small zipline into the water, and a basic restaurant. It's usually quiet in the mornings, but can get busier in the afternoons as schoolkids come to cool off.
