| Location: It is located on the northern side of the Mencilis Massif; 20 km north of Safranbolu on the Karabük-Zonguldak motorway. Its square entrance on the fascinating steep rocks can be seen from the road. It is the upper entrance; there are also two more big entrances behind the cave. |
| Geography and Environment: It is a horizontally developed fossil cave. Entered through a big mouth; it consists of a main gallery and two side passages. The branch in the first passage on left leads into a siphon where the water is collected. Immediately 50 m under the mouth of the cave lies a spring drainage; upsurging by a siphon. The siphon inside the cave is probably connected to the main gallery by a shaft. |
