Do and Dont's in Tehran

Probably Tehran is the first city you will arrive to in Iran, if you are going by plane. It is not the most interesting city in Iran, but you can enjoy it anyway :).

Firstly, BE CAREFUL ABOUT TAXI DRIVERS. Do ask for a price before you go anywhere, otherwise they will have a ride around Tehran and charge you like for limousine. Most of them don't know English (also, if you ask them, they will say "of course", but then it turns out that "of course" is the only thing they are able to say). Learn basic persian phrases, like telling the destination, numbers, bargaining and whatnot. It's useful and not that hard. :)

Secondly, make a plan before you go. Wandering around Tehran is not  pleasant experience, especially in the rush hour. Expect a REALLY bad traffic and pollution. Crossing the street is not an easy skill, and it may give you a heart attack. And so does walking on the pevement, since the motorbike drivers don't care , and drive there as well. And usually faster than you'd expect. I was warned that pickpocketing is a problem in Tehran, but I haven't felt endangered anyhow.
About the pollution... well if you are an asthmatic, do take a hygienic mask. Seriously, I don't have any problems with lungs, but sometimes I was choking of all this dust in the air.

Thirdly, you can skip many places in Tehran, but don't forget to go to the Museum of Jewels , the Bazaar and Azadi Tower. They're just worth visiting.

The bazaar isn't as amazing as in Esfahan, but still impressed me. Maybe you will not find all these amazing hand-made Persian things there, but you will get to see daily life of Iranians. I bought some interesting things there anyway, which I couldn't find anywhere in my country for sure. And again... they're cheap! :D

Transport in Iran

Generally there are three ways of transport between cities- bus, train and plane. We have chosen bus and train, and both were fine.
Transport is generally cheap (they've got a petrol, right? :)). From what we heard, a plane is about 40USD. For both train and bus we paid not more than 5 USD. At first I was more favorable to the train , since I saw how Iranians drive, but now I'd rather recommend a bus.

The train.
The train was just fine. We've chosen "the first class" , which was a simple carriage with couchettes. Not sure if the air conditioning was there, it wasn't unbearably hot, but not cool either. It was possible to sleep there anyway (I slept like a child. But don't forget to drink a lot, I woke up completely dehydrated).
It is also a great opportunity to talk to Iranians, they are so talkative and communicative.
Also, there's a restaurant compartment and water in every compartment.
Oh, and Persian restrooms of course. Not in the best condition. Not at all .
Ah, and the strange thing about the tickets. You can't buy them on the train station , you must go to a travel agency. But it's not far at least :)

The bus
Take the "VIP" buses. They're air-conditionned, with really confortable seats, which you can set in horizontal position. Literally! Also you'll be able to get some snacks and cold water all the time. We had one stop, in the middle of the desert, next to Qom. Really scruffy place, don't eat anything there. :)
