This lake is located in the Govi-Altai province, it is surrounded by sand dunes and drains into the Zavkhan river. The lake encompasses an area of 4km2. The flowers that grow on its edge and the many birds that fly together over its body make this lake incredibly beautiful.

Locals call this the “Switzerland” of the Gobi. Ereen lake has a special structure that does not allow it to be filled up by sand even though it’s located in the middle of the desert. On windy days it looks like the sands are moving, yet even then the lake is still fresh and clear. When people are thirsty, they assume the lake is a mirage because of the how this looks. On very hot and dry summer days, it is amazing to see this deep blue fresh lake.

According to legend, there are 2 host children of the lake. Early in the morning, at sunrise they play on top of the dunes, however when people near they recede into the lakes water. According to legend if you see those kids it symbolizes that you will have good fortune in the future.
