Although the cave was known to the people living in that region, it became open to tourism as a result of the scientific research conducted by Sukru Eroz, a geological engineer from Cebeli Village, between the years 1983-1990.

[1] Prof. Dr. Remzi Dilek and his team from the Department of Geological Engineering at the (Karadeniz Technical University) contributed a lot of research and scientific studies of the cave.

In the area extending between Gümüşhane and Torul, there are extensive formations consisting of various types of extrusive, igneous rock, including andesitic and basaltic lavas, tuffs and agglomerates.

Karaca Cave is rich in dripstone formations of many different shapes and colours, including stalactites, stalagmites, and travertines.

The travertines vary in colour from white to dark blue, revealing the presence of high levels of iron and magnesium minerals in the cave waters.
