Gilit Salt Lake is the largest desert salt lake in the world. Although it is called a lake, due to the huge evaporation, the actual water content of Gilit Salt Lake is very low and the salt content is very high. It is even known as the lake with the highest salt content in the world. The salt content is even comparable to that of the Dead Sea. If you are lucky, you can see mirages in the desert when the weather is clear and the sun is strong.
