Some routes are 10 to 11 kilometers long and all lead to "The Island", a centrally located large atrium.
Due to the difference in temperature outside and inside the cave and the coolness of the air within it, it is one of the attractive attractions for the summer season's hot season.
In the Ali-sadr cave you will encounter fantastic geological landscapes and you can see the miracle of nature closely.
Some caves pass 10-11 km, but still not all canals and communication networks of the cave have been discovered. Now, after a creeping cave, the pedestrian cave begins in the cave, and tourists after a relatively long distance Once again, they have been traversed by boat, but they are now discovered 14 kilometers from the caves, but only 4 kilometers from the streets, which are covered with a light-emitting diode, are visited.
