Moving grass or “Chamli-gul” is one of the most outstanding phenomena in Iran and even all over the world that is located in the heart of nature in Takab and is still a sealed secret. In local language, this area means “an island of grass on the lake”. Chamli Moving Grass is a vast area of reeds whose connected roots to each other on the water and non-attached to the ground has made this phenomenon. This grass is like a moving island with an area of more than 100 square meters on a small lake that changes direction and moves by the wind blowing and airflow or a specific hit.

The grass is floating in the middle of the lake and has totally perfect and well vegetation that does not lose its greenness in summer or winter or in cold weather.
