Ali Sadr Cave, a must-see natural attraction in Iran for cave and mountain enthusiasts.Ali Sadr Cave or Saard, meaning cold, is a grand river-cave system located around 75km to the north of Hamedan (in a province by the same name). It is usually considered suitable for a one-day trip. You can expect lots of local touch experiences because it is among Iranian tourists’ favorite destinations, especially at weekends.

All in all, spending one, two or even three hours, crossing a dark cave by paddle boat and in some parts, walking across some points can be wonderful and special for anyone fascinated in rare natural attractions like this.


Due to a network of watery passageways, channels, and lakes which are spread around over several kilometers, like Katale Khor system in Zanjan province, Ali Sadr Cave is one of the largest water complexes lying and operating under the surface of the earth in the world.

There are no living creatures in the cave’s water and it is totally colorless and odorless. The water is so transparent that one can see to the depth of 10 meters with the naked eyes in ordinary light.

The height of some parts of the cave reaches up to 40 m and the depth of the river in some parts is 14 m. The temperature inside the caves is 16°C and the water is always 12°C, so it is rather cold and putting on some extra clothes may be useful. So far, 14 kilometers of the cave’s canals have been explored, but only some four kilometers have been illuminated and ready to use. In winter Ali Sadr Cave is open from 8 a.m. to 4 p.m., however in summer it’s open till 9 p.m.
