In the hurt of the mountain range, about 25 km east of Tabas, and after the villages of Mehrabani and Kharv (Kharv), there is a beautiful valley path through which water flows, which originates from the springs and waterfalls at the end of this valley. Some of these springs and small waterfalls are hot water and a spring above them is cold water. Hot and cold water move adjacent together without mixing thoroughly.
Also a beautiful and intact historical dam is located at the end of this valley, which is known as the arch or dam of Shah Abbasi.
Shah Abbasi Arch is a historical monument related to the Safavid period, a dam that was built between the two walls of the valley in a narrow passage. The height of this dam is 60 meters and its width is only one meter. There is a short passage under this dam. The task of this dam is to control the passage of large floods that may occur in this valley.
