Iran holds some of the best-preserved Islamic architecture anywhere — the square and mosques of Isfahan, the gardens and poets' tombs of Shiraz, the bazaars of Tabriz — along with Persepolis and the desert cities of Yazd and Kashan. The classic route links them by road or domestic flight.
The guides on this page cover Iran as a whole. Spring and autumn are the practical seasons; summer in the desert and south is extreme. Foreign payment cards do not work, so trips run on cash exchanged locally. Dress codes are legally enforced, particularly for women. Entry requirements and regional security conditions change, and current official advisories should be checked before planning.
