Modern and traditional, secular and religious, rich and poor
Tehran is still relatively one of the safest cities to travel through, particularly considering its size and security. Common sense and the usual precautions against pickpockets in bazaars and crowds should ensure your visit is hassle free. Never take unmarked taxis. Even late at night it is safe in most parts of the city while you will find it still crowded. The fake police that target Esfahan's tourists have also found their way to Tehran in recent years. These are usually uniformed men in unmarked cars flashing phoney IDs requesting to see your passport or search your luggage. It goes without saying that you should just ignore such requests and head to the nearest police station if you feel unsafe. The trouble is that it can be a little hard for the untrained tourist eye to tell these from the real police.
