The island of Palawan, located in the southwest of the Philippine archipelago, is famous for its unique natural attractions. One of the most famous and mysterious is the underground El Nido River, which attracts tourists and explorers from all over the world. This river, hidden deep within limestone caves, is an amazing combination of natural beauty, geological uniqueness and ecological diversity.
Geographic Location and Features#
The El Nido Underground River is located on the west coast of Palawan Island, near the town of Puerto Princesa. It flows through the St. Pauls-Sabterranian River National Park, which was designated a UNESCO World Heritage Site in 1999. The park covers an area of more than 22 thousand hectares and includes not only the underground river, but also the surrounding jungle, mountains and seashore.
The river itself stretches for 8.2 kilometers, of which about 4.5 kilometers are available for tourists. It flows into the South China Sea, but much of it passes through a complex system of caves formed millions of years ago by karst processes. These caves are decorated with stalactites, stalagmites and other bizarre limestone formations that create spectacular underground landscapes.
History of discovery and exploration
The underground El Nido River has been known to locals for centuries, but its systematic study did not begin until the 20th century. In the 1970s, a team of Filipino and American researchers conducted the first detailed studies of the caves and the river. They discovered that the underground system is much more complex than expected and includes many branches and halls.
In 2010, the underground river was included in the list of seven new natural wonders, which attracted even more attention from tourists and scientists. Today it is one of the most popular attractions in the Philippines, visited by tens of thousands of people each year.
Ecosystem and Biodiversity
The El Nido Underground River and its surroundings is a unique ecosystem that combines marine, terrestrial and subterranean habitats. The jungle around the river is home to a variety of animal species including crab-eating macaques, varans, Philippine wild boars and a variety of birds such as parrots and eagles. Rare species of fish and shrimp adapted to life in total darkness can be found in the waters of the river.
The caves are also home to colonies of bats, which play an important role in the ecosystem by pollinating plants and controlling insect populations. In addition, the caves are home to unique species of insects and spiders, many of which have yet to be described by science.
Tourist Attraction
The El Nido Underground River is not only an object of scientific interest, but also a popular tourist destination. Visitors can take a guided boat tour of the river. The route passes through the most impressive parts of the caves, where you can see huge halls decorated with stalactites and stalagmites, as well as underground lakes.
To ensure safety and preserve the ecosystem, tourist access is restricted and all tours are strictly supervised. Tourists are given life jackets and helmets with flashlights so that they can move around the caves safely. It is also forbidden to touch the stalactites and stalagmites so as not to disturb their natural growth.
Environmental Challenges and Protection
Despite its popularity, the El Nido Underground River faces a number of environmental challenges. The increasing number of tourists is putting strain on the fragile ecosystem of the caves and surrounding jungle. Pollution, noise and interference with natural processes can lead to irreversible changes.
To minimize the impact, the Philippine government and local organizations are taking steps to protect this unique place. Strict visitation rules are in place, the number of tourists is limited, and educational programs are being conducted for locals and visitors. In addition, scientific research is being conducted to study and preserve the biodiversity of the region.
Conclusion
The El Nido Underground River on the island of Palawan is a natural wonder that is breathtaking in its beauty and uniqueness. It combines geologic history, a rich ecosystem, and cultural significance to the locals. However, its preservation requires efforts on the part of all who visit the place. Only a responsible attitude towards nature will preserve this wonder for future generations.
If you are planning to visit the Philippines, be sure to include the El Nido Underground River in your itinerary. This trip will give you an unforgettable experience and allow you to touch one of the most amazing natural phenomena on our planet.
