Crossing Turkey to go into Iran
starting from Cesme (west coast Turkey) and having to pass to Iran, there are many routes but - generalizing - one on the north (Ankara, sivas, erzurum, dogubeyazif) and one on the south (konya, adanadyarbakir, Van)
The south one would drive to cross the border with Iran, in the south, at Kapikoy border, smaller custom, while the northern one drives to the most busy Bazargan, (lotta truks etc)
The southern seems to be more panoramic (lake Van, etc)
The distance is not too different, approx 1900/2000 km.
Anyone may give me suggestion on the better one ?(taking into account the customs issues)
