Location: It is located on the northern slope of the Inkaya Hill (515 m) facing Sakarya River; to the immediate south of the Inhisar District; northwest of Eskisehir. It can be reached from the Bilecik-Sögüt-Inhisar-Saricakaya or Eskisehir-Sögüt-Inhisar and Eskisehir-Sarikaya-Mihalgazi-Inhisar motorways. A road leads near to the cave
Structural Properties and formation : It was formed within the Upper Jura Lower Cretaceous aged Bilecik limestones; which is important in improving the solution with its fracture-rich structures; suitable for karstification and cave development. However; insoluble metamorphites underlying the limestones and comprising the karstic bottom level inhibited the cave to grow deeper. It consists of a single gallery with a roof height of 3 to 20 m and width of 4 to 25 m. The bottom is covered by soil; pebbles; debris and big blocks. Located in a vadose zone; it is a fossil cave which halted its development. The Inhisaralti Cave; which is situated 8-10 below looks like a extension of it. Depending on the lowering of the Sakarya River; the underground water in the cave was also lowered; resulting in the formation of a second cave. It is poor in decorations.
Research History: It was explored by MTA; and its map and other characteristics were published in 2001.
Findings: An intense bat population inhabit the cave which is comprised by a very large gallery. The colonies of bats live almost everywhere in the cave.
