Puerto Princesa Subterranean River National Park, Philippines

The Philippine Islands represent a real treasure trove of natural attractions. One of the most famous among them is located on the island of Palawan. Here, in one of the caves, the underground river with the beautiful name of Puerto Princesa flows. It’s located close to the town of the same name. The length of the river is about 8 km. It’s worth noting that the cave is one of the largest in the world. It has several large rooms that strike with diversity and beauty of the stalactites and stalagmites.

At present, the underground river is located in a large national park that also features valuable rare species of flora and fauna. Despite the fact that the underground river is open for tours, it's not as easy to visit it as it might seem at first glance. In recent years, a number of tourists on the island of Palawan increased so much, that it has become a threat to the preservation of the unique natural monument.

Authorities of the island were forced to introduce a limit on the number of people who can visit the cave every day. No more than 900 people are allowed to have a tour daily. Even with such a huge flow of tourists, it’s necessary to book an excursion for a few weeks in advance, as a queue of those wishing to take a boat ride on the underground river is incredibly high. You can try booking a tour while checking in a room of a hotel. One of the best options to stay in the city is Sabang hotel. The thing is that guests of Sabang hotels enjoy special privileges. They don’t need to wait for a permit for a tour for several weeks. Next - Fantastic Forest of Cantabria
