Jomblang Cave is a vertical collapse doline type cave. This cave was formed due to the geological process of the sinking of the soil and the vegetation on it to the bottom of the earth that occurred thousands of years ago. This collapse forms a sinkhole or well which in Javanese is known as luweng. That’s what makes it unique because in the cave there is a cave mouth area of ​​about 50 meters. This is often referred to as Luweng Jomblang. Jomblang Cave is located in Gunungkidul Regency, DI Yogyakarta.

Currently Jomblang Cave is a place for ancient plant conservation and has been developed into a special interest tourist spot which is managed by local residents or residents. To descend this vertical cave, the manager has provided complete equipment according to caving safety standards in vertical caves.

The sunlight streaming in from Luweng Grubug as high as 90 meters forms a pillar of light, illuminating the beautiful flowstone and the depths of the pitch-dark cave. Water dripping from a height also beautifies the scenery. It is not wrong if many people are amazed to come here when they see the nature paintings known as “lights of heaven”.
