Jomblang cave is a vertical cave with dense ancient forest below. A 300 meter alley with its beautiful natural ornament will bring you to the edge of Gua Grubug (Grubug Cave), a place where you can see light from heaven. Jomblang cave is famous for its eerie stories, in fact the locals are scared of the horrible history of the cave. But don’t let this discourage you!!! Once you get to the bottom, all the fear and fatigue will be replaced by a feeling of awe of the dazzling Jomblang Cave. Indeed the journey down the cave is strenuous and needs a lot of fortitude, especially for first timers.
Jomblang is one of hundreds of cave complex in Gunungkidul that becomes well known because of its uniqueness. In 2011, it is used as the object of a program called Amazing Race America. Located on the range of karst hills in the southern coastal spread along Gombong, Central Java up to karst area in Sewu Mountain, Pacitan, West Java, this vertical cave has collapse doline. It was constructed from a geological process when the land and its vegetation vanished into the bowel of the earth thousand years ago. The ruins formed a sinkhole, which in Javanese language was called sumuran or luweng. As a result, the cave which has 50 meter diameter was later named Luweng Jomblang.
To enter Jomblang cave, we need to master single rope technique (SRT). Everyone who wish to do caving in this place should use special equipments based on the caving safety standard in a vertical cave and should also be accompanied by the experienced caving trainers. An adventure to the deep part of the earth was soon started by leaving the basecamp to get to the edge of the cave as the track. There were some tracks in Jomblang cave with various heights, from 40 up to 80 meters. Since this was the very first time for us to do vertical caving, the shortest track, known as the VIP one, was chosen. The first 15 meter from the VIP terrace was a slope that was possibly stepped, and we continued to go down on a 20 meter rope to get to the bottom of the cave. The feeling of scared and nervous when we hung in the air was suddenly disappear when we stepped our feet on the ground.
Surprisingly, the view in front of us was awesome. When we were above, we could only see barren region with hardwood and when we were hanging on the rope to get to the bottom, we could only see karst, but in the bowl of Jomblang cave we could really see the green view of fertile and dense vegetation. Various kinds of moss, fern, bush, and big trees densely grew. A forest with different vegetation from the land above it was usually called ancient forest. Since the geological process of the land happening in the past, those vegetations were continuously growing up to now.
Once at the bottom of the cave, you can relax a bit before continuing to trace the 300 m/984 ft tunnel that connects Cave Jombland with another cave called Grubung, where you will be able to see light from heaven!! To attempt to descend the cave, you need to always be accompanied by a qualified guide and must be equipped with tools which have passed safety standard for caving. The best time to cave here is between 10:00-12:00 when the sun is shining above your head so as to enjoy the heavenly light.
