Puerto Princesa Underground River: How to Book, Permits & Fees
Puerto Princesa Travel Guide
The single most important thing to know about the Puerto Princesa Underground River: you must arrange it in advance, because the national park admits only a limited number of visitors each day on a government quota. Here is how booking, permits and fees actually work — and whether to join a tour or do it yourself. When you are ready, compare river tours on Puerto Princesa Tours.
What the Underground River is
Officially the Puerto Princesa Subterranean River National Park, it is a UNESCO World Heritage Site (inscribed in 1999) and one of the New 7 Wonders of Nature (2012). The star is an 8.2-kilometre underground river, of which about 4.3 kilometres is navigable, running through a limestone cave beneath the Saint Paul Mountain Range and out to the sea. Our Underground River page covers the natural history in full; this guide is about getting yourself there.
Do you need a tour, or can you DIY?
You can visit independently, but most people don’t, and for good reason. Going it alone means arranging your own transport to Sabang, securing a cave permit, paying the separate fees, bringing valid ID, and potentially queuing for a boat slot behind the organised groups — waits of two to three hours are common on busy days. A tour rolls the transfers, the permit, the fees, the boat and lunch into one booking, and gets you a slot. Here is the trade-off:
| Approach | Roughly costs | You handle | Best for |
|---|---|---|---|
| Join a tour | From about $47 per person | Nothing — pickup, permit, fees, boat and lunch are arranged | Almost everyone |
| Do it yourself | Around ₱1,085 (about $25) in fees and boat, plus your own transport | Transport to Sabang, the permit, ID, fees and the wait | Confident independent travellers with time to spare |
For the small difference in price once you add transport, the organised full-day trip is the stress-free choice for most visitors.
The permit and the eco-fee
Entry to the cave requires a government permit, which is processed in advance — which is exactly why advance booking is required and why tour operators ask for your details ahead of time. You will also pay a small Eco-Tourism Development Fee (around ₱150, roughly $3), and you should carry valid photo ID, which is needed for the permit. On a tour these fees and the paperwork are handled for you; doing it yourself, you arrange them at the park office or wharf.
How to get to Sabang
The park is reached from Puerto Princesa city by a 1.5 to 2 hour road transfer to the village of Sabang, then a short motorised boat ride from Sabang Wharf to the park’s beach landing. From there a paddle boat takes you into the cave. Tours include the drive and both boat rides; independently, you would take a van to Sabang and pay for the boats there. Coming from further afield?

What the cave tour is like
The visit itself is a roughly 45-minute paddle-boat tour covering about the first 1.5 kilometres of the river. You wear a helmet and life vest, an audio guide narrates the formations, and the boatman uses a spotlight to pick out the stalactites, stalagmites and the thousands of bats and swiftlets overhead. Guides keep noise to a minimum to protect the wildlife, so the cave stays hushed and dark — part of what makes it feel so otherworldly.
Best time and how far ahead to book
Visit in the dry season (roughly November to May) for the calmest seas on the Sabang crossing; in the wet season, rough water can cancel the crossing at short notice. Book several days ahead in peak season, and keep a spare day in your itinerary in case weather postpones your slot. Ready to lock it in?

What makes it a New 7 Wonder
The park is far more than a pretty cave. Its 22,202 hectares run from mountain to sea and protect some of the most important lowland forest in Asia, with well over 800 plant species and around 195 kinds of birds recorded, plus macaques, monitor lizards and the bats and swiftlets that roost in the cave. Because the river’s lower half is tidal, freshwater and marine habitats meet in one system — a rarity that helped earn the UNESCO listing and, later, Ramsar wetland status. Knowing this before you go makes the quiet glide through the cave far more meaningful.
Who it suits, and accessibility
The trip works for most fitness levels — the cave portion is a seated boat ride — but it is a long day with an early start and a winding road, so pack motion-sickness tablets if you are prone to them. It is not wheelchair accessible: boarding the boats and the cave landing are uneven. Most group tours welcome children, though some combination trips set minimum ages, so check the details when you book.
Combination tours: Ugong Rock and fireflies
If you want more from the day, two add-ons pair well with the river. Ugong Rock, near Sabang, offers caving through narrow passages and a zipline back down over the countryside. And an evening firefly-watching river cruise turns a river day into a full day-and-night out. Combination tours bundle these together, which is handy if your time in Palawan is short. Compare the standard, combination and private options on the homepage.
Photography and etiquette in the cave
Photography is allowed, but conditions are challenging: the cave is dark, the boat moves, and flash is discouraged so as not to disturb the bats. A phone or camera that handles low light does best, and a strap or case guards against drops over the water. Above all, keep noise to a minimum — guides ask for quiet so everyone can hear the audio and the wildlife is left undisturbed. Following these small courtesies keeps the experience special for the next boat, and protects a site that belongs on every Palawan itinerary.
