“Caspian Sea, the largest landlocked lake in the world, is located in northern Iran. The Iranian Caspian coast including the three littoral provinces of Gilan, Golestan and Mazandaran, with its thick forests and large-scale rice paddies presents a striking contrast to the dry inner plateau of Iran.
A four-hour drive from Tehran, the Caspian is Iran’s Riviera, with a narrow plain of paddyfields and orchards separating the sea from forested mountains where bears and leopards roam around ruined Mongol castles.”
