The cave contains a natural 'gong' rock that serves as a percussion instrument, producing distinct tones when tapped.
The cave system consists of seven distinct rooms, with names such as Sendang Bidadari and Ruang Kristal.
The stalactites and stalagmites within the cave are considered 'living' as they continue to grow due to active water seepage.
The site was officially opened as a tourist destination in 1996 after being discovered by local residents.

It is a karst cave system located within the Punung district of the Pacitan Regency.

Wear footwear with high-traction soles as the internal paths can be slippery due to constant dripping water.
Bring a microfiber towel or tissue, as the humidity inside the cave will cause perspiration and may result in dripping water on your clothes.
Carry a small flashlight if you want to inspect the rock textures more closely than the ambient LED lighting allows.
Avoid visiting on local public holidays or weekends if you prefer a quiet experience, as the cave becomes very crowded.
Avoid touching the stalactites, as oils from human skin can disrupt their natural mineral growth process.
