This mysterious 8-kilometer valley near the city of Tabas is considered as one of the most important natural resources in Iran and it is said that is the place of jennies and demons.
The erosions during so many years have built beautiful structures which are beyond imagination. Every corner touches your heart and every color takes you to heaven. Many explorers compare there to the Grand Canyon in USA.
The local people believe that Kal jeni is still used by demons as they hear their voices but the truth is that the powerful winds blowing there make those voices and it is so amazing that the place of demons seems like a comfortable place for angels.
There are also so many chambers which used to be used by humans and many believe that they belong to the followers of Mithraism or even Zoroastrianism.
If you are a seeker of natural comfortable and calm places, we suggest you visit the Grand Canyon of Iran.
Remember that the best season to visit there is autumn.
