Now there's a lot of propaganda in the west that leads us to believe Iran is dangerous and travellers shouldn't go there.
Obviously there are major political disagreements between several governments and the Iranian government and this should be taken into account.
But at a human level I have met many Iranians travelling elsewhere in the world and have found them to be friendly, charming, and hospitable. I have also met several western travellers who spent time in Iran, including hitchhiking around the country, who only have wonderful things to say about the country and its people.
As a traveller I've learned to trust the most what I hear from other travellers about a destination, especially ones which prefer similar ways of travel to myself. I've also learned to trust the opinions of inhabitants of countries bordering on the destination country the least.
Yet some people still insist that Iran is not safe for a traveller, or that it depends greatly on which area of Iran.
I can look up for myself the general travel advisories issued by governments and disclaimers in WikiVoyage. So please don't regurgitate those an answers.
I want to know from travellers who've been there, from Iranians, or from references to specific incidents targeting foreigners/westers about which parts of Iran are no problem, and which parts should be avoided, even by experienced intrepid travellers.
(I realize any advice won't apply to Israeli citizens unfortunately. I'm Australian.)
