Caspian Coast of Iran, also known as Northern Iran (Persian: shomal) is a beautiful tropical and highly touristic region along the coast of the Caspian Sea.
The “sea” is, in fact, the world’s largest salt-water lake bounded by Russia in the north.
This region is, by far, the top tourist destination for the domestic travel because of its tropical wet climate. Foreigners go see Persepolis or Yazd, in the middle of the desert. But the vast majority of Iranians already know the arid landscape that covers most of Iran. They have a soft spot for the lush greenery of shomal.
The north coast is bounded by the Alborz Mountains on the south side, which are covered by deep forests. The region comprises the three provinces of Gilan, Mazandaran and Golestan, which are major sources of agriculture.
