Every tourist must take certain necessities depending on his/her itinerary and time. For example the kind of clothing is different from a location to another, so taking suitable ones is very important. Since camping facilities are available in many tourist sites, having the needed equipment is important.    
There are different maps and guidebooks for each province and major cities published by related organizations. Most of them are bilingual (English and Farsi) available in all newspaper stands, airports, hotels etc. These materials have also been published in other languages like Arabic. In the "Series of Guidebooks To Iran" there are the maps of major cities in Farsi, English and Arabic.
