Travel Iran

Female tourists must wear scarves to cover their head and neck. It can only be removed in private when there are no people around. The chador is required to visit certain holy sites. Generally these can be hired at the entrance. The arms and legs, at least up to the calf should be covered. If your ankles and feet remain uncovered, you should put on socks or thick tights. Avoid ostentatious clothes, jewellery and make-up. For male tourists, shorts and short-sleeve T-shirts are strongly inadvisable. Generally, non-muslims may enter the mosques (you can keep your shoes on, except when walking on the carpet). Ask before taking pictures, especially of women. It is strictly forbidden to take snapshots of administrative and military buildings.
Be patient! Time and deadlines are not always respected. Have an open mind for the stringence of certain customs may make you lose your spontaneity. Know that a passport bearing an Israeli visa is never appreciated.
