Siyalan is a giant mountain that rises to the south of the Caspian Sea south of the coastal town of Shahsavar (Tonkabon) in the western portion of the Central Alborz Mountains of northern Iran.

In a few short Kilometers, this valley reaches the narrow strip of land between the Caspian Sea and the Alborz Mountains. Read More
