| Location: It lies to the southeast of the Uluabat Lake. By turning left from the Cali junction on the Bursa-Mustafakemalpasa motorway; Doganalan Village is reached; following the Mustafakemalpasa signs. In order to reach to the exit-mouth of the cave; a turn should be made to the direction of Uncukuru-Ayvaköy before Doganalan. As the crow flies; there is a 4 km distance between the mouths of the sinkhole and the spring. |
| Geography and Environment: It was formed within the Jura-Lower Cretaceous limestones. It grew horizontally except the entrance. It is a through cave with double entrance. There is a vertical descent of 17 m immediately after the entrance; and a ladder should be used for descending. The mouth of the entrance; where the Karadonlu Creek disappears forming a 10 m waterfall; can be easily found along the course of the water. There are plenty of lakes inside the cave; which can be passed despite the fact that the level of water increases in spring. After the hall right down the descent; the main gallery starts; continuing with an inclination of 1-2% and the width varies between 4 and 10 m. There are many chimneys; which are considered to carry the water from the surface dolines and which also have large travertine depots underneath. Surfaces covered with a slippy layer makes it difficult to climb. Among decorations; particularly of interest are stalactites. |
