The existence of nature’s carvings through million years in the beautiful form of stalagmites and stalactites in the corridors and halls is showing off and adds to the beauty of the Cave.
In some corridors animals’ skeletons were found which are not similar to nowadays animal and probably belong to the extinguished generations of the past ages.
It’s good to stay in Zanjan’s hotels, plan one day trip to Cave and back to Zanjan again. It will take about 6 hours ( 2 hours driving there ,2-3 hours visit the Cave , 2 hours drive back to Zanjan). (Rich C.; Reviewed March 2016)
This cave system is much less popular than Ali-Sadr Cave further south - which is a shame, given the extent and quality of the grottos. There is the (unfortunately expected) colored lighting, but even that cannot hide magnificence of the glaze-like stalactites.
Getting there can be a bit complicated without a private car: Shared taxis might take you as far as Garmab from either Bijar (changing at Khoorkhoreh and Tatardeh) or Zanjan (probably changing in Qeydar), from where you can hire a taxi. Alternatively, hire a taxi for a day - we paid appr $15 Bijar return. This would allow for a combined visit with Takht-e Soleyman. (a_appelt from Aarhus, Denmark; Reviewed June 2016)
The name, Katale Khor, means “mountain of the sun”. Geological studies in 1984 showed that the cave formation dates back to the Jurassic period. It is believed that the cave is connected to Ali Sadr Cave in Hamadan province. The road from Zanjan to Katale Khor passes Soltaniyeh, an ancient Ilkhanid city. The cave was discovered about 90 years ago. It has many remarkable scenes that is rare to see in other area even if exist. I took several photo from the different part of 2500 meters walking distance within the cave. (Kaveh H. from Ottawa, Canada; Reviewed April 2016)
