Alisadr: World’s largest water cave located in Hamedan

Alisadr: World’s largest water cave located in Hamedan

As one of the main natural attractions of the western province of Hamedan Province and the world’s largest water cave, Alisadr is ranked among the most popular sites of Iran with thousands of visitors year-round, especially in the spring and summer.

This cave is located in Kabudarahang, a town located 60km from the provincial capital city of Hamedan. The distance between Kabudarahang and Alisadr Village is 50km, wrote.

Evidence shows that during the Safavid Period, locals used cave water through hand dug canals, but they did not know anything about the cave until 1963, when a group of 14 climbers had the responsibility to discover the cave’s length, width, depth and height by making a narrow entrance of about 50cm leading to one of the main parts of the cave.

The hole that only professional climbers could get through remained the only access to the cave until 1974, when Abdullah Hajiloo, who headed the Hamedan Mountaineering Board, expanded its width by five meters, with the help of locals. The following year, they founded a concrete platform set for walking visitors, and with the provision of lighting facilities, Alisadr was prepared for the public.

Alisadr is among the few water caves in the world. Its Jurassic Period rocks take you back to 190 million years ago. As you walk through the entrance, you will be greeted by a cool atmosphere that will make you forget the heat outside. The lake here is so clear that its bottom can be seen. You have to wear a life jacket and get on the boat and go through the natural labyrinth of the cave. You get off the boat somewhere and continue your journey.

The cave lake is fed by underground springs and by rain water intrusion. There is no living creature in this water except unicellular organisms, algae.

Reaching 14 meters wide in some parts, the lake water is neither salty nor colored. So far, about 14 kilometers of the cave passages have been discovered, but only four kilometers are illuminated.

Crossing the winding corridors with crystalline ceilings and boating in clear water through the fascinating stalagmite formations that have been shaped over millions of years is what awaits you there. The strange names you see on the boards also represent strange shapes of stones; names like pillars, eagle claw, dragon claws, etc.

Due to the lack of light in the cave, living creatures find it difficult to live in such environment. Plants can’t grow, except for some unicellular organisms and algae that have been recently introduced to the environment from outside, considered to be invader elements.

A few years ago, a scuba diving team encountered an unknown crustacean while exploring the waters of Alisadr Cave, but they were not able to sample the species. After that, a team of university students entered the cave and found the creature with a length of two centimeters. It looks blind and does not need light. The creature probably feeds on minerals and unicellular organisms of the cave.
