Puerto Princesa Subterranean River National Park
📍 Address: Puerto Princesa City, Palawan, Philippines
Palawan Island, often called the Philippines’ last frontier. Located amidst a vast natural landscape, approximately 80km northwest of Puerto Princesa City in the central part of the island, is the ‘Puerto Princesa Subterranean River National Park,’ designated a UNESCO World Natural Heritage Site in 1999. In 2011, it was also chosen as one of the ‘New7Wonders of Nature,’ attracting numerous travelers daily as one of the Philippines’ most iconic global tourist attractions.
The highlight of this national park is its ‘navigable underground river,’ one of the world’s longest, stretching approximately 8.2km. An emerald green river flows towards the sea through a massive limestone cave, carved out over countless millennia by heavy rains cascading onto the limestone bedrock. The island’s indigenous people once believed this dark cave was inhabited by ‘spirits’ and never ventured inside. This subterranean river, preserved untouched until Europeans first explored it in the late 19th century, is truly a place where you can experience the Earth’s mysteries firsthand.
Tourists embark on a paddle-powered banca boat for an approximately 40-45 minute tour, venturing about 1.5km from the cave’s mouth, which opens widely to the sea. For environmental protection, lighting inside the cave is minimal, and the thrill of navigating the pitch-black depths, relying solely on the boatman’s flashlight, is exhilarating. Inside the enormous dome-shaped cavern, reaching up to 60m high and 120m wide, unique rock formations and stalactites resembling Jesus Christ, dinosaurs, and vegetables successively appear. This is a must-visit spot to witness the artistic beauty created by nature and an unchanging, unique ecosystem from ancient times.
To the Underworld Where Spirits Dwell! The Reality of a Cave Tour That Sharpens Your Senses
The underground river boat tour is not merely a visual spectacle; it’s characterized by an intense stimulation of all ‘five senses,’ including smell and hearing. As you approach the cave entrance, you’re first met by the scent of animals and the distinctive ammonia odor emanating from the droppings (guano) of tens of thousands of bats inhabiting the cave. It might be surprising at first, but this is proof of ‘authentic nature,’ untouched by artificial creations.
During the tour, you’ll proceed while listening to a Japanese-language audio guide provided at the entrance, allowing you to deeply understand the history and geological formation of the Philippines. However, for a more profound experience, try removing your earphones briefly mid-tour. The space filled with only the sound of bats flapping and screeching in the darkness, the gentle plink-plonk of subterranean water dripping from the ceiling, and the quiet swish of the boat paddling through the water creates a mystical atmosphere, as if spirits truly reside there.
While you can observe bats clinging to the ceiling at close range inside the cave, it’s strictly forbidden to carelessly open your mouth and look up. Bat droppings and water droplets can fall from above, so make sure to securely wear the provided helmet and life jacket.
The Journey from Sabang Village: Beware of Wild Monkeys and the ‘Nightmare Shuttle Van’
From the area around Puerto Princesa Airport to the entrance of the underground river, it’s about a 2-hour journey by shared shuttle van (minibus). Most tours use these vans, which are sometimes described locally as ‘nightmare shuttle vans.’ They speed through incompletely paved or unpaved roads and winding mountain paths, making it absolutely essential for those prone to motion sickness to take motion sickness medication beforehand.
After disembarking the van, you’ll arrive at Sabang Village, a small port town that serves as the base. From here, you’ll transfer to another motorized banca boat, swaying with the waves to a nearby beach. From there, it’s a few minutes’ walk along a jungle boardwalk called the ‘Monkey Trail’ to finally reach the cave entrance. As you might wait for an hour or so for your boat in Sabang Village, travelers with flexible itineraries would be wise to consider spending a night in Sabang Village, which boasts quiet and beautiful beaches, to target an early morning tour with fewer crowds.
Furthermore, wild crab-eating macaques and large monitor lizards inhabit the area around the Monkey Trail. Monkeys, in particular, are very clever and react sensitively to the sound of plastic bags that might contain food. They sometimes quickly snatch smartphones and even plastic bottles, so keep your belongings securely in zippered bags and walk carefully to avoid attracting their attention.
Your Perfect Pre-Visit Preparation Guide
To comfortably navigate the underground river tour, preparation tailored to the local environment is essential. First, choose your attire assuming you ‘will definitely get wet.’ Boarding and disembarking the boat happen at the water’s edge, meaning you’ll be submerged up to your knees, and water droplets will fall from the cave ceiling. The best attire would be a swimsuit or quick-drying rash guard underneath shorts and secure sports sandals.
Additionally, since you’ll be walking through a jungle area, there are many insects like mosquitoes. From an environmental protection perspective, it’s recommended to bring DEET-free organic insect repellent cream or spray and reapply it frequently. For cameras and smartphones, keeping them in a waterproof case is advisable as a precaution against splashes.
Finally, regarding restroom facilities: there are no well-equipped restrooms inside the cave or around the waiting beach. It’s a golden rule to stop at a local restroom (which may be paid) before departing Sabang Village’s port to avoid a common traveler’s pitfall. Enjoy a memorable adventure at Puerto Princesa Subterranean River National Park, where the wonders of nature blend with a touch of survival!
