Geography of the Puerto Princesa subterranean River National Park
The geographical position of the Puerto Princesa Underground River and the surrounding protected area is worth noting if you’ve got to experience one of the most educative tours. The cave system of the Island of Palawan describes some very considerable issues of interest.
Let’s talk about geography, but not too much of it anyway!
Puerto Princesa Underground River is a tropical area which we can look at from several points of views. Its closeness to the sea makes it a true estuary that creates unique conditions in geography. In fields such as biology, meteorology, hydrology and mineralogy, there’s always something to pick from this spectacular wonder of nature.
For how can we know Palawan without searching deep into its rich geography?
Palawan is a historical region covering an area of 12,000km2. It is located between 11050’ and 12020’ latitude N, and 117000’ and 120020’ Longitude E in the South-Western Region of Philippines Archipelago. This place is not far from Borneo.
Mountainous, narrow and elongated nature
The nature of the Island is basically mountainous, narrow and elongated. The island is divided into three tectonic sectors by the two important N-S depressions corresponding to lowlands. Along the depressions dividing the northern from the central sector is the St. Paul Dome karst ridge.
The unique underground system of the river has made Puerto Princesa subterranean River National Park a popular world heritage site since 1991. The underground river was first explored and recorded in 1930. This was witnessed by some writings on the walls of the outpouring in Rockpile.
In 1973, a Hungarian geologist called Balazs carried out the first sketch of the focal gallery of the cave. Later in 80’s, two expeditions from Australia navigated the entire branch and some side tributaries and this pushed the development of the river and the cave further. Since then, methodic research and some interesting explorations have been carried out and Puerto Princesa Underground River has been elected as one of the 7 wonders of the Nature.
The scenery of the area is a typical tropical karst characterized by irregular plateau, large depressions, cones, towers, pinnacles and large tunnels.
This underground river is a cave stream that stretches about 8 km and it collects water from a wide surface basin. It is diverts into the sea through large galleries overflowing with water.
How To Get to the Puerto Princesa Subterranean River National Park
With all the geography, you might be wondering then how you can find your way to this must see attraction, right? The main access to this underground wonder is from the sea. When you get there, you’ll realize that on the side of the beach is some water stream carving a shallow canal through its rich coralline sand. It’s at this point where you stop and say, “Take memories only, leave only footprints; just as Chief Seattle would.
A few meters on your way upstream is when you reach the long awaited lagoon surrounded by calciferous cliff. Right at its foot is the portal which opens its way into the Subterranean River and this marks the peak of your trip.
Where adventure begins…
If you thought adventures is dangerous, dare routine. If you’ve been used to the trips to the park, beach life, hiking and canoeing, you’ve got to have the guts to tour Puerto Princesa Underground River. The experience will leave you speechless, and then turn you into a storyteller.
Before you get there, this is how the journey is got to be. The main underground stream you encounter runs in large tunnels coupled with lateral minor diverting passages. At some point, you’ll discover some upper old relict galleries that join with the dynamic one through its hefty chambers.
It’s a magical experience to find out how the main resurgence of the Cabayugan River represented by this cave disappears into the limestone about 7km upstream.
Your journey through the caves doesn’t end here…
Discover more submarine
A few hundred metres further E, you’ll be surprised to hit upon another marine spring cave. The beauty of this cave is how it collects the water sinking in the closed basins arising along the east side of the karst. It’s called the Little Underground River.
When you look at the hydrologic setting of the area, you’ll come into a clear understanding of how things unfold here. If you’re keen enough, you’ll tell of at least two drainage systems; one drained by the Underground River and the other by the Little Underground River. Be observant and discover more submarine and other unknown springs.
As mentioned earlier, the entry of the Underground River on the Coast is at the Sea level. Up to about 6km of the cave is inside the mountain.
Let’s now talk about the navigable part of the underground river.
Experience on the navigable part of Puerto Princesa Underground River is fantastic. Tasting its salty water that lies under a thin sheet of fresh water is in itself mysterious. And just to mention, the sheet is only a few centimetres thick.
But is this the usual state of the water? Actually, this condition is only experienced during the dry season when there is no rain. Salty water gets cleared during overflow moments and slowly returns once the floods are gone.
The mixing of the fresh and the saline water is phenomenon and its effects on the caves cause meticulous processes of rock corrosion leading to the formation of water level notches. On its down streams, the mixing corrosion has been proved to produce typical forms of coastal caves characterized by lateral conduits, waterline notches and spongework.

The faunal diversity of Puerto Princesa Underground River is moderate with over 254 terrestrial vertebrate species and over 165 species of birds.
