Cavers enter the cave through its upper entrance in Doğanalanı, where it starts with a 17 m (56 ft) descent.

[4] The otherwise horizontally developed cave has a length of 4.86 km (3.02 mi),[4] which makes it the longest in southern Marmara Region and the eighth-longest in Turkey.

[3] The cave features speleothems such as stalagmites, stalactites, pillars, wall and drapery dripstones, and around 60 pools and ponds of size 3–4 m (9.8–13.1 ft).

The water level of the ponds and the lake varies depending on seasonal effects.

But in 2012 the Mağara Araştırmacıları Derneği Bursa Şubesi (Bursa Branch of Cave Researchers Association) objected to these plans with the argument that the cave will lose its naturalness and turn into a picnic area.
