Select participants and date
You step off the air‑conditioned van with the heat folding around you and a green wall of rainforest rising like a live map. The road from Puerto Princesa eases into palms and limestone karst; at Sabang, wooden bancas bob in a narrow inlet, waiting to carry you toward the cave mouth. The river itself seems to breathe—dark water slipping into a throat of stone where light stops and the cave begins.

Adventure Tips
Expect government‑timed entry
The cave is managed by the national park and entry is scheduled—allow time for lines and delays, especially on cruise ship days.
Bring a waterproof bag
Bancas and the jungle path can be wet; protect cameras and phones with a dry bag or waterproof case.
Closed‑toe shoes for the approach
The trail to the jetty can be muddy and uneven after rain—wear grippy, covered shoes for the jungle walk.
Go early to beat crowds
Morning departures reduce wait times and offer better light and cooler temperatures on the transfer road.
