Avisho or Abisho Cave is also one of the notable attractions of Gilan Province, located in Masal in a mountainous area amidst the forests of Shanderman district.
Masal is home to more than 17 large and small caves, with the largest one being Avisho, situated at an altitude of 1300 meters above sea level in a low-water valley.
Avisho is a Talysh language meaning “a place where water falls.” It is said that the cave got its name from a spring located nearby.
So far, cavers and mountaineers have explored and discovered about two kilometers of the astonishing depths of this cave. This cave was registered in the National Heritage List in 2010.
Avisho Cave is a limestone and water cave with seven springs and a river flow inside. In such a way that the water flow can be seen from the beginning to the end of the cave, it has nine main shafts and one secondary shaft. Working your way into the cave, you will see unique and diverse limestone formations. These formations have been created as a result of the dissolution of limestone rocks in water.
The stalactites are among the attractions of this cave, hanging either as columns or located on the ground, and it is interesting to know about the formation of these stalactites, which are actually limestone deposits. Most caves are formed in limestone and gypsum rocks, which contain calcium carbonate that can easily be dissolved by acid.
During rainfall, raindrops absorb carbon dioxide present in the air, becoming acidic and capable of dissolving limestone rocks in them. Therefore, when acidic water containing limestone drips from the cave ceiling, vaporizing, the limestone deposits remain, forming these spectacular stalactites.
On the way to Avisho Cave, you will encounter lush green forests with stunning views and enchanting springs that will make your drive enjoyable.
