Are there official guides in Iran that one can hire? I think sometimes most of Iran and Iraq are in San Diego so perhaps I can track down a guide family here :).
Yeah!
Lonely planet 2005 version, as guide book, is a good one!
All kinda of maps and guides are also available inside the country!
But the travel agency that prepares your entry permit (VISA) will also provide you with a translator or a guide too!
Just make sure you get tour packs from reliable agencies.
Go and visit Shiraz, Esfehan, Masouleh, Kish Island and Tehran!
You'll be fine!
