Puerto Princesa Underground River Tour: A Complete Guide

Miracles do exist, and one of them hides on the beautiful island of Palawan, in the Philippines, the island I spent three whole weeks exploring. The one to blame for me adding Puerto Princesa to my itinerary is the Puerto Princesa Underground River, one of the New7Wonders of Nature since 2012 and a UNESCO World Heritage Site since 1999.

 

Officially it goes by Puerto Princesa Subterranean River, and it sits about 76 km north of Puerto Princesa, the capital of Palawan. The road to it’s long, roughly two hours each way, but the landscapes are spectacular and completely worth the time spent in the back of the van.

 

 

 

Nature really showed off here. Over a few million years it carved a river straight through the mountain: 8.2 km of water winding past stalactites and stalagmites before flowing directly into the emerald-green sea. That last part makes it one of the very few underground rivers on the planet that empties straight into the ocean. It’s one of those experiences that leaves you open-mouthed, in the best possible way.

 

I first visited in January 2017, as part of a longer Southeast Asia trip, and the memory still gives me goosebumps. I came back to Puerto Princesa again in 2026, this time as part of a cruise itinerary through Asia, so I know exactly what has changed since and what still holds true. In the lines below I’ll walk you through my whole experience, step by step, and give you everything you need to know to plan your own visit.

Things to know before visiting the Puerto Princesa Underground River

 

The Puerto Princesa Underground River is one of those places that sounds like a myth until you’re sitting in the boat, staring up at a ceiling covered in bats. Before you go, here are the essentials that will help you understand what you’re getting into:

 

• It’s part of the UNESCO World Heritage List since 1999, and in 2012 it was named one of the New7Wonders of Nature, which is exactly when tourism here exploded.
• It’s one of the longest navigable underground rivers in the world, with a total length of 8.2 km. Only about 4.3 km are actually navigable, and the standard tour covers roughly the first 1.5 km, which is more than enough to leave you speechless.
• The river flows directly into the sea, with its lower half rising and falling with the tides. Very few underground rivers on Earth do this.
• The cave hides some genuinely huge chambers, one of them called the Cathedral, and a fairly rich fauna: thousands of bats and swiftlets inside, plus monkeys, monitor lizards, and birds in the forest around Sabang.
• You need a permit, and numbers are capped. Only 900 visitors per day are allowed in, to protect the site. Most permits are handed to tour agencies, so if you’re going independently, you have to sort yours out in advance. In peak season they sell out weeks ahead.

 

Visiting the Puerto Princesa Underground River, step by step

 

1. Getting your tickets and permit

 

You’ll probably be staying somewhere in or near Puerto Princesa City. Tourism isn’t hugely developed here, but when it comes to the Puerto Princesa Underground River, plenty of agencies organize the visit. You can book online, sign up through your hotel (if they don’t run tours themselves, they’ll have a partner agency), or just walk around town, where people will happily sell you the tour at negotiable prices.

 

I stayed at Rodolfo’s Royale Hotel and, although they had the trip on offer, I went with another agency recommended by Max, a lovely local who drove us from the airport to the hotel in his tricycle on our first day. Best decision, because it came out cheaper.

 

One important thing that has become stricter over the years: it’s a “no permit, no entry” site, and only 900 people get in per day. I got lucky and managed to reserve the day before, but if you want to guarantee your spot, especially in high season, book a few days ahead.

 

If you’re doing it independently rather than through an agency, you’ll need to secure the permit yourself at the park office in the city (near Mendoza Park) or at Sabang, so factor that in. It’s worth checking the latest permit rules on the official park website before you go, since they change from time to time.

 

 

2. The drive to Sabang

 

Early in the morning, around 8, we were picked up from the hotel in a large, comfortable van with the all-important air conditioning. We quickly got to know our local guide, whose English was good and whose little stories kept us entertained across the two hours on the road.

 

Her name was Elvie. We were the first ones picked up, so we made several stops at other hotels before finally hitting the road properly. After two hours of ups and downs through beautiful forested hills, taken at a speed that felt at odds with the number of curves, we arrived at our destination.

 

3. Sabang Beach: the wait and the boat to the river

 

The place you arrive at isn’t the river itself, but a lovely beach, Sabang, where you’ll wait for an hour or two while your guide goes to collect the visiting permit from the Sabang authorities.

 

I already know your first reaction reading this: “and what am I supposed to do all that time?” Well, you’re on your own, and you get to decide. You can wander among the stalls, grab a fresh mango, banana, or pineapple, take photos, or just plant yourself on the beach and enjoy the turquoise waves.

 

 

One heads-up: Sabang has cheeky monkeys and the occasional monitor lizard roaming around, so keep an eye on your bags and don’t wave food or sunglasses at them. Once your guide is back, there’s still a bit more waiting for the boat that takes you to the next beach. Don’t despair, the scenery around you is tempting enough that the time doesn’t feel wasted. All you really need is patience and the thought that you’re about to visit one of the wonders of the world.

 

When the wait is finally over, one of the dozens of wooden-framed boats becomes your ride to the beach that separates the forest from the hidden miracle. Once you land, you have to photograph those impressive cliffs, especially the sign with the name of the place you’re about to enter. Careful not to lose track of your group, because they’re also your companions inside the cave. You cross the forest together until an unbelievably pretty sight greets you: a small green lagoon.

 

 

 

4. Going through the Underground River

 

You’re already wearing a life jacket, so now you get the rest of the gear: a helmet to protect you from the harmless drips inside the cave, and audio equipment for the route. You’ll climb into a paddle boat with about nine other visitors plus the boatman who steers it, and spend the next 45 minutes listening to the audio guide, available in English and a few other languages.

 

You’ll hear genuinely impressive statistics about the rock formations and the creatures living inside the mountain. I thought the audio guide was very well done, and our boatman made a point of lighting up every stalactite it mentioned with his flashlight, so we could follow the whole presentation with live examples.

 

 

What impressed me most was the nativity scene, sculpted over millions of years by falling droplets, and one of the largest cave chambers in the world, inside a section called the Cathedral. A few meters past the entrance, total darkness takes over.

 

All you can make out are the bats hanging from the ceiling and the other boats coming and going. The experience is unique, and it makes you reflect on the sheer power of nature and respect the work it put in over such an unimaginable stretch of time.

 

5. Lunch

 

One of the best things about the tours in Puerto Princesa, and across Palawan in general, is that the meals are included in the price, and they’re genuinely hearty and tasty. That was the case here too. After the tour, we were taken back by boat to Sabang beach and treated to a buffet at a local restaurant, with no shortage of rice, vegetables, chicken, and noodles.

 

Tip: there are some skinny, scruffy dogs hanging around the beach. Maybe slip them a little bit of your lunch. They’ll be grateful, and you’ll see it in their eyes.

 

 

6. The way back to Puerto Princesa

 

No surprises for the final step. You get dropped back at your hotel the same way you were picked up. The tiredness will hit at some point, and you won’t admire the scenery with quite the same enthusiasm on the way home. My advice is to sleep the whole ride, so you don’t have to nap once you’re back at the hotel. Palawan is the kind of place where any wasted time gets regretted by the end of the trip.

 

Best tours for the Puerto Princesa Underground River

 

Given the permit system and the daily cap, booking a tour is honestly the easiest way to visit, and it’s how I did it. A standard tour from Puerto Princesa City includes hotel pickup and drop-off, the van transfer, the permit, the boat rides, and the buffet lunch, so you don’t have to juggle the bureaucracy yourself. Compare a few options, check what’s included and what the current price is, and book ahead, because the good dates fill up fast in high season.

 

My top tips for the Underground River tour

 

1. Bring a waterproof bag for your things, because you’ll likely hit some big waves. If you don’t have one, the street vendors on the beach sell them.
2. Try not to book through your hotel, as the price is usually higher. Agencies around town offer better deals. We managed to get our tickets for 400 pesos less than the original price, which worked out to roughly an 8 dollar discount per person.
3. Reserve at least two or three days in advance. Puerto Princesa has become popular, and with the daily cap now at 900 visitors, you want to make sure you’re one of them, especially in peak season.
4. Don’t plan anything else for that day. You wake up very early and the activity eats up the whole day, so you’ll either have no time or be too tired for anything more. If you still insist, see tip number 6.
5. Wear flip-flops, a swimsuit, shorts, and a t-shirt, because your clothes will get wet.
6. Bring insect repellent. The waiting area and the surrounding jungle have mosquitoes and sandflies, and you’ll thank yourself later.

 

 

What to know before visiting the Puerto Princesa Underground River (Q&A)

 

Is the Puerto Princesa Underground River worth it?

 

Absolutely. It’s one of the New7Wonders of Nature for a reason. Yes, the day is long and involves a fair bit of waiting, but gliding through a pitch-black cave under a ceiling of bats, listening to how the formations took millions of years to shape, is the kind of thing you don’t forget. If you’re the kind of traveler who chases natural wonders, like the Plitvice Lakes in Croatia, this one belongs on your list. If you’re in Palawan, don’t skip it.

 

 

Do I need a permit, and how do I get one?

 

Yes. It’s a strict “no permit, no entry” site, capped at 900 visitors a day. The simplest route is to book a tour, and the agency handles the permit for you. If you go independently, you secure it yourself at the park office in Puerto Princesa City (near Mendoza Park), ideally a day or two ahead, or at Sabang. In high season, permits can sell out weeks in advance.

 

How far is it from Puerto Princesa City?

 

About 76 km north, which translates to roughly two hours by van on a winding but scenic road. Most people stay in the city and do it as a full-day trip. If you’d rather cut the drive, sleep in Sabang instead.

 

 

How much does the tour cost?

 

A full tour from Puerto Princesa with transfer, permit, boat rides, and lunch generally runs around 2,200 to 2,500 pesos (roughly 40 to 45 dollars) per person, sometimes a bit more depending on the operator. Doing it independently can be cheaper, but once you add the permit, audio guide, environmental fee, boats, and transport, the savings are smaller than you’d expect and the hassle is bigger.

 

Can you swim in the Underground River?

 

No, swimming is not allowed inside the cave, both to protect the ecosystem and for safety. You can, however, swim at Sabang Beach while you wait, just mind the currents, which can get strong.

 

 

What’s the best time to visit?

 

The dry season, roughly January to May, is ideal, with calmer seas and a lower chance of the boat transfer being cancelled due to rough conditions. I went in January and had a great run of weather. Whenever you go, book early and start your day as early as possible.

 

How long does the actual cave tour last?

 

The paddle boat ride through the cave lasts about 45 minutes to an hour, covering roughly the first 1.5 km of the river. The whole outing, though, from pickup to drop-off, takes most of the day, around 6 to 7 hours.
