The amazing Chahkooh canyon is a view of eroded rocks with the depth of 100 meters that is one of the most important tourist attractions of the island in the middle of the monolithic stone mountain cut crosswise. The valley has four straits from four sides, which have been wide at first and their width gradually reduced insofar as the walls distance may be about half of a meter in some parts.
There is little light in space because of the high walls.
The type of Chahkooh rocks is sedimentary known as limestone related to the Zagros Mountains. Chahkooh is a wonderful valley created by water erosion and dissolution led to the creation of parallel lines in the Chahkooh valley walls, deep and long slots and a variety of holes in shape and ledges on the perpendicular body of the valley and rocky streams in the valley floor.
