About this tour
Float through an underground river inside a natural cave system in Bali's Tegallalang region on this four-hour expedition. You'll drift through passages carved by water over centuries, past limestone walls and rock formations, with enough current to keep things interesting without demanding paddling effort. The experience balances genuine exploration with relaxation—a rare chance to move through an active cave river rather than simply viewing one from a walkway.
Highlights
- Float through an active underground river within a natural cave
- Navigate gentle rapids at a leisurely pace
- Limestone formations and geological features throughout
- Private transport included to and from cave entrance
- Lunch provided after the activity
- Safety gear and briefing before you start
What to expect
You'll arrive at the cave site and receive a safety briefing covering the tube descent and river navigation. After gearing up with helmet and life jacket, you'll wade into the cave entrance and board your tube. The river carries you through dark passages lit by your helmet lamp, past shadowy rock walls. Water temperature is cool and refreshing. The flow includes small rapids that jostle you gently but don't require active paddling. The entire float lasts roughly two hours depending on current. You'll exit, dry off, and have lunch before heading back.
Good to know
Moderate fitness required—the cave entry involves wading and tube handling. Not suitable if you have spinal issues, are pregnant, or have cardiovascular concerns. Wear water shoes or sandals with grip. The cave is genuinely dark; your helmet lamp is essential. Water level rises during heavy rain; check conditions beforehand.
