What is Jomblang Cave?
A huge collapsed sinkhole in the Gunung Kidul karst region, south-east of Yogyakarta. Visitors are lowered about 60 m on ropes into an ancient forest at the bottom, then walk through a muddy cave passage to Grubug cave, where, around late morning, sunlight pours through an opening in the roof as a dramatic beam: the "light of heaven".
Price and booking
The standard fee of about Rp 500,000 per person covers the descent and ascent by rope, a guide, helmet, harness and boots, and lunch. Many tours from Yogyakarta add transport (and sometimes Pindul Cave tubing or Timang Beach) for an extra fee. Check whether the entrance fee is included before booking a package, and bring cash.
Limited places
Because the light only appears for a short window, there's essentially one main session a day with a limited number of people. Book a few days ahead, more in Indonesian holidays.

History and geology
Jomblang Cave is a vertical sinkhole, about 60 m deep, formed thousands of years ago when the ground collapsed into the limestone karst of Gunung Kidul. At the bottom, an ancient forest grows in the sinkhole, and a passage leads to Grubug Cave, where a hole in the ceiling lets a shaft of sunlight, the "light of heaven", shine onto the cave floor in the late morning. The site was opened to visitors in the 2010s, and numbers are limited to protect it.
