Crossing from Sea:
Very few foreigners use the sea routes, though these makes an interesting way of arriving or departing. The problem lies with sporadic boat services, so before venturing on a sea trip, you should contact a travel agency or information offices at the ports to check for updated schedules. On the Gulf side, car ferries operate between Dubai (UAE) and Bandar Abbas (Iran), and between Bahrain and Bushehr (Iran). On the Caspian Sea, boats run between Baku (Azerbaijan) and Bandar Anzali or Noushahr (Iran).
