Is Isfahan safe for solo female travelers?

In general, for ladies I would say moderate safety. The most important problem would be with men trying to harass you orally or physically. Also you must be very careful with your personal belongings such as your phone or wallet. Also, be careful with motorcycle

It's fine but there is some problems with ur hijab and we have lots of religious people so the may act like strict parents in street about what you wear But not all of them And others are really hospitable and kind

In general, Isfahan is classified as one of the safest cities in Iran, much more safe than the capital and other major cities. I've personally never had any dangerous or concerning experiences although I must mention the frequent catcalling we experience on the streets if we're walking alone.
