Suitable for travelers in good general health who can handle short hikes, uneven cave passages, and periods of standing on boats.
A compact two‑day loop from Puerto Princesa that pairs the Puerto Princesa Underground River with a zipline, mangrove paddle, coastal waterfall walk, and a guided cave exploration—finished with a spa session to unwind.
The first light at Sabang slices across limestone cliffs and spools of mist that cling to the sea. You step off an air‑conditioned van with a salty wind in your face and an audio headset in your pack, the promise of an underground river—and two full days of kinetic, varied terrain—waiting ahead.

Phones and cameras ride better in waterproof sacks—cave boats and mangrove paddles are splash-prone.
Morning departures mean calmer paddle conditions, smaller crowds at the Underground River, and cooler hikes to the falls.
Expect sand, muddy mangrove banks, and slippery cave steps—grippy, quick‑dry footwear helps.
Bring pesos for park fees, food stalls, and tips; some remote vendors don’t accept cards.
The Puerto Princesa Underground River sits within karst terrain formed over millions of years and was designated a UNESCO World Heritage Site and one of the New 7 Wonders of Nature for its intact cave system and biodiversity.
Park permits and guided access minimize impact in sensitive cave and mangrove zones; visitors should stick to paths, avoid single‑use plastics, and use reef‑safe sunscreen to protect coastal ecosystems.
Protects electronics and a change of clothes during boat rides and waterfall visits.
Provides grip on wet rocks, mud and cave steps while remaining comfortable in heat.
Useful for navigating darker cave sections and for hands‑free lighting in the Hundred Caves.
Sun protection for beach and zipline; repellent for mangrove and forest sections.
