The name of the cave comes from the Turkish word “gök” which means “sky”. It is supposed that this cave has served as a sanctuary thousands of years B.C.
Gouk In is located along the river Dishlik dere, on the road to Krumovgrad and near the Rock Arch in the Oreshari region. From the inside of the cave there is a beautiful view of the surroundings and the river Dyslick dere.
The opening to the cave is wide with an oval shape. Because of its wide-formed entrance, the cave is relatively well lit. The cave is relatively small and has only one level with a displacement of only 5 meters. It is a dry cave, there are no calcite formations such as stalactites and stalagmites. Today, it is inhabited by bats. The cave is not an official tourist destination but is accessible for visits. In order to get into it, you must climb a not very steep stretch above the river.
