Ağcaçal Cave - Sinop
It is located in the Agcaçal area at the top of Cevizlibağ Village, 25 km away from Durağan. Some of the columns at the entrance of the cave, which are reported to have formed in millions of years, have been damaged by treasure hunters and unconscious citizens. However, there are many figures formed as a result of melting of limestone in the galleries in the lower parts.
