The Jomblang Caves are a part of a cave system that reaches the whole of Gunung Kidul. The cave had formed around a thousand years ago when the soil and vegetation had collapsed under the surface of the earth. It had created a sinkhole that was roughly 50 m wide and up to 80 m deep. Over the thousand years, supported by the 'Heavenly Rays,' which is a daily 3-hour window of sunlight that enters the cave, helped an incredible underground forest take root.
The Jomblang Cave are vertical caves with a forest with a diverse type of vegetation from the land above it. Some of the flora still exists because of the water from the Kalisuci river at the bottom of the cave. Besides the cave being unique, the cave has also had a history of the allegedly being used as a place to execute PKI victims and as the location of mass murder.
