Ali Sadr Cave

The UNESCO tentative listed Ali Sadr Cave as a world natural heritage. It is 75 km away from Hamadan and brings awe and astonishment to whoever cast his eyes on it. This outstanding cave system, discovered by a group of mountaineers in 1963, grants you access to the longest subterranean water caves in the world. Formed during the second geological era (about 190 million years ago), this astonishing cave is carved out by various water springs near the cave. The eye-catching rock formations of the cave are created by the deposition of pure calcium carbonate during several long years. The labyrinthine network of channels inside the cave leads to several halls and chambers with their walls and ceilings covered with stalactites. In some sections, where there is no water, you can see beautiful stalagmites on the ground.

As you enter the cave, there is a short walking path which takes to the water. Then, to continue your subterranean adventure, you have to get on one of the boats available there. During your journey, you will pass through various unbelievable paths with a stable air and water flow. The height of the ceiling reaches up to 10 meters in some points. In the middle of the cave, there is a large pool, about 5-meters deep, which multiplies the beauty of your surrounding space with the calmness of its cold and clear water. The water level fluctuates during the year, as its different traces are marked on the walls. Interestingly, there is no fauna inside the cave. In several parts, the rock formations take special forms, for example, an inscription of the name of God in Arabic transcription (Allah).

So far, only about 14 km of the total area of the cavern is discovered, nevertheless, it attracts thousands of visitors from all over the world every year.
