Six kilometers from Qom, there is a mountain that has been considered by the mystics from long time ago. According to narrations and quotations, on the top of this mountain there was a cave that was the place of worship of khidr the prophet. Then a mosque was built in the cave, and there are still people going to the mosque for worship.
From the top of this mountain you can see the whole city of Qom. This mountain is also considered by the residents of Qom in terms of recreation, and on the holidays many people go to the mountain.
