Moderate fitness: able to sit in a low paddle boat for extended periods and manage short stairs or uneven footing at entry points.
Venture four kilometers into Puerto Princesa’s subterranean river on a private paddle‑boat journey that stretches the usual cave tour to about three hours. Expect close quarters, dramatic limestone formations, and a hearty Filipino lunch back on Sabang beach.
The motorboat pushes away from Sabang’s mangrove fringe and the island’s heat draws back like a curtain — suddenly the mouth of a cave yawns ahead, a dark throat that will swallow the day. On this private 4‑kilometer excursion into Puerto Princesa’s subterranean river, visitors trade bright sky for an amphitheater of stone: low-slung chambers where water carries echoes and the boat’s paddle ticks against limestone ribs.

Tours run best November–May; book at least a week ahead during peak months to secure private slots and hotel pickup.
Cave lighting is limited in deeper sections; a dimmable light helps with footing without disturbing wildlife.
Use dry bags for cameras, passports and phones — humidity and splash from the paddle boat are constant.
This trip involves cramped seating and long sitting periods; not recommended for pregnant travelers or those with serious back or heart conditions.
Declared a UNESCO World Heritage Site, the park preserves karst landscapes and an underground river that reflects Palawan’s complex geological uplift and sea‑level changes over millennia.
Park authorities limit visitor numbers and enforce no‑touch rules to protect fragile formations and bat roosts; choose operators who support local conservation fees and community programs.
Secure footing during boat transfers and on wet docks is essential.
Protect electronics and documents from splashes and humid cave air.
Hands‑free light helps when moving in darker cave sections and for photography.
Breezes on the water and sudden tropical showers make a lightweight layer useful.
