If you are planning to visit Iran one of the areas you must see is the Zagros Mountains . While trekking remote valleys and settlements you will come across nomads from pre-historic era. This article in Nature will shine light on the authenticity of the area. All of the treks I guide and organize are in remote pristine areas of the Zagros well away from the touristy zones. You will need to be physically and mentally fit and prepared to trek for several days on difficult terrain carrying your heavy backpack. The reward is out of this world. https://www.nature.com/articles/srep31326
