Descend nearly 60 meters into a karst sinkhole and watch a single column of sunlight pierce an ancient underground forest. This guided, full‑day Jomblang Cave tour combines hands‑on vertical caving with a riverine cave system and dramatic photo opportunities.
More ways to explore the area's outdoor wonders
You step to the edge of a collapsed roof and the world falls away: a vertical shaft yawns down through green shafts of light, and the forest inside the sinkhole seems to breathe on its own. The Kalisuci river at the cave's base pulls at your attention, its current shaping pools and passageways below as sunlight threads through a single circular opening—locals call it the “heaven’s light.”
