The Puerto Princesa Underground River is 8.2 kilometers long. The river runs through the Puerto Princesa Subterranean River National Park in the Philippines, about 30 miles north of Puerto Princesa. To get to the river’s mouth, take a short ferry ride from the town of Sabang. The river flows directly into the sea after passing through some of the world’s most beautiful rock formations. The river has gained worldwide acclaim and attention, prompting it to be named one of the New Seven Wonders of Nature in 1012.
The river runs underground for 8.2 kilometers, passing through natural rock formations such as caves, stalactites, and stalagmites.
Only 4.3km of it is easily accessible to tourists. If tourists want to travel the remaining 3.9km, they must obtain a special permit. Wading in the river is possible for some of the 3.9km.
Some of the rock formations resemble objects and images like a horse, cacao fruit, a mushroom, and the Holy Family.
One of the rock formations in the cavern through which the river flows resembles a naked lady.
The St. Paul Underground River is another name for the river.
The river is bounded to the north by St. Paul Bay and to the east by the Babuyan River.
Tourists can take a fiberglass boat down the river.
In 2010, geologists and environmentalists discovered a second floor to the river. This led them to believe that there were also waterfalls in the cave.
Geologists and environmentalists discovered a dome inside the cave that rises 300 meters above the river. They also discovered large bats, new river channels, and marine creatures, among other things.
The lower half of the river contains brackish water, which contains more salt than fresh water but not enough to be classified as salt water.
Despite the fact that it is called an underground river, it is located above sea level. Its water enters St. Paul Bay.
Sabang would take an hour and a half to reach by car from downtown Puerto Princesa. It’s only a short ferry ride from the nearby town of Sabang from there.
The monkeys in Puerto Princesa Subterranean River National Park have become so accustomed to human feeding that they will now steal food from visitors.
It’s common to hear bats chattering inside the open chambers of the Puerto Princesa Underground River trip. Tourists usually wear helmets because bats have a habit of pooping on them.
The tourists’ helmets are also important for protecting them from loose stalactites falling from above. Stalactite is a mineral that hangs from limestone caves and is a type of cave formation.
Along the river, stalactites are also common. Stalagmites erupt from the ground. They are cave formations caused by mineral dripping from above.
The Puerto Princesa Underground River was once thought to be the world’s longest underground river. When a longer underground river was discovered in Mexico, this was proven false.
On January 28, 2012, the Puerto Princesa Underground River was named one of the New 7 Wonders of Nature.
