This unique cave was caused by a geological shift that created a massive sinkhole that stretches some 300 vertical feet below the surface. Travelers who wish to explore the rocky crags and impressive natural light shows this destination is famous for must navigate a well-worn path using a single rope line, which may prove challenging for some. Not for the faint of heart, visitors must wear coveralls, boots, a helmet and headlamp on their journey into Jomblang.
While vegetation above ground is mostly barren and dotted with hardwood trees, adventurers will find lush green landscapes and fertile fields visible from one of the cave’s most popular vantage points, which makes this trip a truly memorable experience. Those in the know recommend hiring an expert guide since the descent can be rather technical, and local operators will also be able to point out rock, crystal and fauna to interested travelers.
Jomblang Cave is located in Gunungkidul in the Karst Hills. Visitors can access Luweng Grubug via an easy to navigate 300-meter alley that connects the two. Travelers will find the best time to visit the caves is between 10 a.m. and 12 p.m., when the sun lights paths from above.
