In 2010, a group of environmentalists and geologists discovered that the underground river has a second floor, which means that there are small waterfalls inside the cave. They also found a cave dome measuring 300 m (980 ft) above the underground river, rock formations, large bats, a deep water hole in the river, more river channels, and another deep cave, as well as marine creatures and more. Deeper areas of the underground river are almost impossible to explore due to oxygen deprivation.

The park has a limestone karst mountain landscape. St. Pauls Underground River Cave is more than 24 kilometres (15 mi) long and contains an 8.2-kilometer-long (5.1 mi) underground section of the Cabayugan River. The river winds through the cave before flowing directly into the West Philippine Sea and is navigable by boat up to 4.3 kilometres (2.7 mi) from the sea. The cave includes major formations of stalactites and stalagmites, and several large chambers, including the 360-metre-long (1,180 ft) Italian's Chamber with approximate 2.5 million square meters volume. It is one of the largest cave rooms in the world. The lower portion of the river up to six kilometers (3.7 mi) from the sea, is subject to tidal influences. Until the 2007 discovery of an underground river in Mexico's Yucatán Peninsula, the Puerto Princesa Subterranean River was reputed to be the world's longest underground river.
