One of the important caravanserais located in Semnan province and south of Garmsar is "Ain al-Rashid" which is located a short distance from Ghasr-e Bahram caravansary.
Eshkaft-e Salman Cave is actually two cave entrances, one of which is much larger than the other. The caves are not very deep and at the deepest point of the caves there is enough light to see.
Ghasr-e Bahram Caravansary is located in the middle of a vast plain and there are no other artificial structures around it for a relatively long distance.
