Rig-e Jenn is a desert region with sandy hills (dunes) in the central desert of Iran. This area is located south of Semnan, east of the salt lake, north of Anarak and west of Jandaq.
Due to its large size and lack of springs or water wells, the area has not been the passageway for caravans in the past, and only a few groups have moved to the area in recent years.

There are no springs or water wells in this area.
In 1900, Sven Hedin, a Swedish desert explorer, crossed the western and southern margins of Rig-e Jenn. He later wrote in the Book of Deserts of Iran about Rig Jen in detail. In 1930, Alfons Gabriel passed through the southern part of the Rig-e Jenn. Since 1997, groups of desert explorers have gone to different parts of the Rig-e Jenn with desert vehicles and even on foot.
