Blue Lagoon

There are several Blue Lagoons (1, 2, 3).

Blue Lagoon 1 is the most visited place by travelers. You can see people playing in the water (jumping on trees).

Each place has its pros and cons.

Watch the YouTube video. Cleanup is very tidy.

You can rent a buggy and drive on dirt roads to the Blue Lagoon.

Also, you can do various activities (zipline, longtail boat, kayak, cave exploration on a tube) in Vang Vieng, so please refer to the video https://youtu.be/m_1jCknKasw .
