For over a thousand years, Iran was the beating heart of the ancient Silk Road — the great trade highway connecting China, Persia, and Rome. Our Iran Silk Road tour 21 days follows the original Shāhrāh-e Khorāsān (Khorasan Highway) through its authentic caravan cities: Tabriz, Qazvin, Tehran, Isfahan, Yazd, Kerman, Damghan, and Mashhad — four of which served as the capital of Persia. Iran’s Silk Road legacy still breathes in its grand bazaars, 999 Safavid caravanserais, a Zoroastrian fire burning since 470 AD, and some of the world’s most breathtaking Islamic architecture. This Iran Silk Road tour 21 days is your chance to travel the road itself — not just visit the cities it created.
