About Underground River Puerto Princesa
Natural History and Recognition
The Underground River Puerto Princesa forms the centerpiece of the Puerto Princesa Subterranean River National Park, located about 76 kilometers northwest of Puerto Princesa City proper in the Philippines. It has earned multiple international recognitions, including a UNESCO World Heritage Site designation in 1999, thanks to its outstanding universal value. This natural wonder is also revered as one of the New7Wonders of Nature, an accolade that placed it in the same league as prominent global landmarks such as the Amazon and Halong Bay. Geologically, the subterranean river extends for approximately 8.2 kilometers beneath the Saint Paul Mountain Range. Its portion accessible by small paddle boat tours stretches around 4.3 kilometers, allowing visitors to witness the enchanting interplay of water and limestone in the caverns. One remarkable feature is the direct interaction between freshwater and seawater, as the river empties into the West Philippine Sea. This phenomenon creates a brackish environment near the cave entrance, fostering ecological diversity that includes both marine and terrestrial species.
Origins and Geological Formation
Millions of years ago, tectonic movements lifted coral reefs and marine deposits above sea level, creating the foundation for the karst landscapes seen in Palawan. Over millennia, rainwater dissolved the limestone, carving out intricate passageways and chambers within the rock. This slow but constant erosion process, known as karstification, formed the awe-inspiring network of caves that define the Underground River Puerto Princesa today. Stalactites and stalagmites within the cave have been sculpted by a consistent trickle of mineral-rich water, leaving behind sedimentary layers. Some formations resemble mushrooms, gothic spires, giant vegetables, and even human figures—sparking intrigue and imagination among visitors. The cave’s internal environment is further shaped by tidal influences, where saltwater from the sea penetrates during high tide, altering the salinity and temperature in the lower sections of the subterranean passage.
Cultural Relevance
Long before it achieved worldwide fame, the underground river had already been part of local folklore. Indigenous groups such as the Tagbanua and Batak have historically recognized the cave’s existence, weaving legends about spirits and deities residing in its depths. Although early communities were hesitant to explore the mysterious tunnels, these stories underscored the sacred connection people felt to this extraordinary subterranean realm. With the advent of organized tourism, the cave transformed from a site of local folklore into a leading example of eco-tourism in the Philippines.

Interesting Facts about Underground River Puerto Princesa
A Tidal Subterranean River
Unlike most underground rivers, the Underground River Puerto Princesa is directly influenced by ocean tides, creating a part freshwater, part saltwater habitat. At high tide, seawater can penetrate the lower sections of the cave, introducing a brackish environment that supports marine organisms. At low tide, the subterranean water flows more freely into the sea, catering to freshwater species further upstream.
Bats, Swiftlets, and Remarkable Wildlife
High above the cave floor, thousands of bats roost during the day, venturing out at dusk for insect hunts. Coexisting with them are swiftlets, small birds that craft their nests on cave walls using saliva. These nests, historically prized for bird’s nest soup, remain protected by local regulations to ensure minimal disruption to avian reproduction cycles.
Rare Minerals and Formations
The limestone corridor hosts at least 11 minerals, including the rare manganese phosphate mineral “Serrabrancaite.” Many visitors marvel at stalactites and stalagmites shaped like giant mushrooms, cathedral spires, or whimsical creatures. Slow and continuous mineral deposits have sculpted these features for eons, turning the cave into a vast natural art gallery.

Cave Microclimate and Environmental Conditions
The interior of the Underground River Puerto Princesa is typically cooler and more humid than the outside environment. Temperatures generally range from the low to mid-20s Celsius, but humidity can be high, often exceeding 90%. This microclimate is essential for the survival of cave-dwelling fauna, including specialized insects, crustaceans, and microbats that rely on stable temperature and moisture levels. Moreover, the cave’s ventilation depends largely on air currents passing through openings near the river’s mouth and other fissures in the limestone. These currents help regulate carbon dioxide concentrations emitted by bats, decomposing organic matter, and human visitors. Managing the volume of daily tourists indirectly controls CO2 levels inside the cave, making the 900-visitor cap a strategic move for preventing abrupt ecological shifts.
Stalactites, Stalagmites, and Other Speleothems
Speleothems refer to secondary mineral deposits formed in caves, encompassing stalactites (hanging from the ceiling), stalagmites (rising from the floor), flowstones, and helictites. Their coloration can range from white calcite to brownish or greenish tints due to mineral impurities like iron or copper. Some spires reach several meters in length, while others appear more delicate, resembling thin soda straws. The formation rate of these speleothems is extremely slow—sometimes just a fraction of a millimeter per year—making them priceless geological archives. Disturbing or breaking even a single stalactite can destroy centuries of natural development. Consequently, touching cave walls or formations is strongly discouraged to preserve their fragile integrity.
Guano as a Nutrient Source
Bat and swiftlet guano accumulates on cave floors, providing nutrients that sustain a host of smaller organisms—such as insects, arthropods, and bacteria. These in turn feed salamanders, fish, and other species adapted to life in perpetual darkness. The entire subterranean food web hinges on the cyclical influx of organic matter, demonstrating how organisms both inside and outside the cave are interdependent. Interestingly, significant guano deposits have economic value in some cave-rich regions, where they are harvested for fertilizer. However, in Puerto Princesa Subterranean River National Park, guano collection is regulated or prohibited to maintain ecological stability and respect the site’s heritage status.
