I'm just back from a trip in Iran. I made more than 4,000 km in two weeks: Tehran, Zanjan, Hamadan, Kermanshah, Shush, Ahwaz, Shiraz, Yazd, Esfahan, Kashan, Qom, Tehran. I used the map all the time. I found it easy to use. The major historic and archeologic sites are on the map. The secondary roads of interest are shown. The mountains are correctly represented. All the roads we followed in our trip are on the map. I found little inaccuracies in the layout of a few secondary roads, but they did not bother me. The scale is 1:2,000,000. I recommend this map to any traveler in Iran with or without a guide.
