With the most UNESCO sites in the entire Central Asia region and the 10th most in the world, Iran is a land of natural and human feats that transcend generations, environment, and dynasties. You could dedicate an entire month to exploring the 24 UNESCO sites that fall between the Gulf of Oman, the Caspian Sea, and the Persian Gulf, and still hardly scratch the surface.
What makes Iran particularly intriguing is the mosaic of both human and natural diversity: from Armenian Monastic sites, royal residences from the Qajar era, cave dwellings from agro-pastoralists, preserved Persian civilizations, Roman art, Zoroastrian volcanic sanctuaries, colossal sand formations, and so much more.
With an endless amount of ways to incorporate UNESCO sites into an itinerary, the question at the top of your mind will be how soon you can come back. Visiting Iran is a trip of a lifetime.
