Opposed to general misconception Iran is a relatively safe country for tourists & travellers. However, like everywhere else in the world, It is good to take some general precautions.Pickpocketing might happen so watch your wallet and valuable goods. Robberies and assaults are rare, but not unheard of. Travellers have hitchhiked across deserts, stayed in the homes of strangers and left bags in restaurants and cafes without any problem. Tourists are advised to avoid boarder to Afganistan as some routes are used for drug trafficking. But there are no issues along the main tourist trails.
