Fakıllı Mağarası is simply named after the town Fakıllı where it is located. The through cave is located in upper cretaceous limestones. The interesting thing is that you visit the main passage which is the course of a river, at least most of the year. The tour starts with a walk uphill through a pleasant park to the upper entrance. The river flows through channels below the concrete trail, it was obviously quite tricky to build a trail in the riverbed. Inside the upper entrance it is redirected back into the natural riverbed, and flows through the cave beneath the trail. The tour ends at the lower entrance where the river emerges again.

A show cave in a river cave has various problems. If the river floods during the rainy season in winter, the cave might be closed because of the flood. The water typically floods the trails in various places and the cave is not safe. Also the river brings dirt and sediments which may cover the trail and make it slippery. And finally there are drawbacks with a through cave. The outside air flows rather freely through the cave which causes a big change of temperature depending on season and weather conditions. This is quite exceptional for a cave.

River caves show erosional forms caused by the mechanical weathering and erosion by the water. But this cave also has some nice speleothems. They are obviously located high above the reach of the water and in side chambers. The cave is a show cave for many years and the iron railings show massive corrosion caused by the water of the cave river.
