Select participants and date
The van eases out of Puerto Princesa before dawn and the road becomes a ribbon through palms and limestone ridges. Wind-bent trees lean as if pointing the way north; fishermen on the shoreline wave sleep from their small banca boats. After an hour or two the pace changes — the air smells of mud and salt, the mangroves grow thick, and a cluster of karst towers appears like weathered sentries guarding the river entrance. This is Sabang, and the underground river waits.

Adventure Tips
Arrive early
Morning departures are cooler and typically have fewer boats waiting at the cave entrance—plan for a 6–8 hour day including transfers.
Bring waterproof shoes
The walk to the river can be muddy and the boat dock wet; closed-toe water shoes or sturdy sandals prevent slips.
Pack cash for local fees and tips
Some small local surcharges, souvenirs, or guide tips are often paid in cash at Sabang.
Protect cave wildlife
Turn off flash photography inside the cave and remain quiet—bats and nesting birds are sensitive to disturbance.
Local Insights
Wildlife
- Long-tailed macaque (crab-eating macaque)
- Various bat colonies and nesting swiftlets inside the cave
History
The park was designated a UNESCO World Heritage Site for its intact karst systems and biodiverse coastal forests; local Tagbanua communities have long managed resources here.
