The Puerto Princesa Underground River
A Natural Marvel
The Puerto Princesa Underground River is located about 76 kilometres northwest of Puerto Princesa City on Palawan’s western coast. The river flows through a dramatic cave system surrounded by the protected forest and limestone landscapes of the Puerto Princesa Subterranean River National Park. Visitors enter the cave by small boat, travelling through a dark passage where stalactites, stalagmites, and enormous chambers create an unforgettable underground landscape.
- A navigable underground river
- Limestone karst formations
- Cave chambers
- Stalactites and stalagmites
- Forest-to-sea ecosystems

The site is widely recognised for its geological history and its role as a habitat for wildlife and a livelihood source for local tourism workers.
Why the Underground River Matters
Protecting a Global Treasure
The Puerto Princesa Subterranean River National Park protects an exceptional natural landscape. It includes a river flowing through caves before reaching the sea, framed by forested mountains and coastal habitats. The park supports wildlife and habitats that depend on responsible management.
"Every visitor has a role in reducing waste, respecting wildlife, and following capacity limits."
- The geological history of Palawan
- A rare cave-and-river ecosystem
- Habitat for wildlife
- A livelihood source for local tourism workers
- A global symbol of Philippine natural heritage
- A reason to invest in environmental protection
- A learning site for students and researchers
- A model for responsible nature tourism
The park's appeal should never outweigh its protection. Every visitor has a role in reducing waste, respecting wildlife, and following capacity limits.

Visiting the Underground River on 11 November 2026
Planning Your Adventure
A visit on PPUR Day may be memorable, but it also requires careful planning. November falls within a favourable travel period for many visitors, though rain and sea conditions can still affect schedules. The Underground River is open daily from 8:00 a.m. to 4:00 p.m., except when extreme weather conditions require suspension.
- Hotel pickup in Puerto Princesa
- Air-conditioned van transport
- Sabang Wharf transfer
- Boat crossing to the cave entrance
- Underground-river paddle-boat tour
- Audio guide or local guide
- Lunch stop
- Optional mangrove tour
- Optional zipline or other Sabang activity
The cave portion of a typical visit lasts about 45 minutes, though the full excursion from Puerto Princesa City often takes a full day.
Permits and Visitor Capacity
Ensuring a Safe and Sustainable Experience
A permit is required to visit the Puerto Princesa Underground River. Daily entry is limited by the site’s official carrying capacity, which has been reported as 900 visitors per day. This limit exists to help protect the cave system and maintain a safer visitor experience.

Sabang: Gateway to the Underground River
Exploring Beyond the River
The gateway community for Underground River tours is Sabang, located west of Puerto Princesa City. It is where visitors usually transfer from road transport to boats heading for the cave entrance. Sabang is worth more than a quick stop. It has a quieter coastal character than Puerto Princesa City and offers access to beaches, mangrove areas, restaurants, and forest scenery.
- Sabang Beach
- Mangrove paddle tours
- Local seafood meals
- Forest scenery
- Wildlife watching
- Beach walks
- Community-run tourism activities
- Nature-based accommodation
Stay overnight in Sabang if you want a slower visit. This can reduce the pressure of an early-morning city departure and gives you flexibility if weather affects boat schedules.
Puerto Princesa Before and After PPUR Day
Exploring the City
Puerto Princesa City is the starting point for many Underground River visitors. It has enough attractions to make a two- or three-night stay worthwhile. The Baywalk is ideal for an early-evening walk, waterfront food, and city views. It may also host PPUR Day-related public activities if the 2026 programme includes city-centre events.
- Palawan Heritage Center: A visit can give useful context on Palawan’s Indigenous peoples, local history, and the diverse communities that shape the province.
- Baker’s Hill: A relaxed family-oriented stop for snacks, gardens, and casual sightseeing.
- Iwahig Firefly Watching: A guided firefly tour can be a peaceful evening activity. Choose a responsible operator, avoid excessive lights, and do not disturb wildlife.
- Honda Bay: Island-hopping is a separate activity from the Underground River. Keep a buffer day between tours, especially in November, in case weather affects boat departures.
Responsible Travel at the Underground River
Preserving Nature's Beauty
Responsible travel is essential in protected areas. Small actions help reduce stress on the park. The cave environment is sensitive. Stalactites and stalagmites take extremely long periods to form, and touching them can damage their surface.
- Bring a reusable water bottle.
- Keep food and wrappers secured.
- Never feed monkeys or other wildlife.
- Stay quiet near animals.
- Follow guide instructions inside the cave.
- Do not touch cave formations.
- Do not use flash photography.
- Keep phones on silent during the cave tour.
- Wear reef-safe sunscreen for separate water activities.
- Do not leave rubbish at Sabang Wharf or the cave entrance.
- Use licensed guides and boat operators.
- Respect weather-related cancellations.
