Sabang Underground River

The Sabang Underground River is a subterranean river located in Saint Paul District, in south-western Saint Vincent Division, near the town of Sabang. It is a popular tourist area and is probably the most famous underground river in the world.

It can be accessed by boat from Sabang, and tours inside the cave are permitted, but some areas are off-limits. The river is located under the steep and sharp Saint Paul Mountains, in a national park of the same name. It is a heavily protected area.

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 300m 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.

On November 11, 2011, Puerto Princesa Underground River was provisionally chosen as one of the New7Wonders of Nature. This selection was officially confirmed on January 28, 2012.
