Yeak Laom Lake is located about 5 kilometers southeast of central Banlung. This beautiful lake is a crater formed after a volcanic eruption over 4000 years ago; the diameter of this lake is about 800 meters and it bears about 50 meters of clear water.

At one end, there are two wooden platforms for tourists to view the lake up close, but some people cannot resist a dip to feel the warmth of the water for themselves.
