Puerto Princesa Subterranean River National Park, located on the western coast of the island of Palawan in the Philippines, is a UNESCO World Heritage Site renowned for its stunning natural beauty and biodiversity. It features an extraordinary limestone karst landscape, including an 8.2-kilometer-long underground river that flows directly into the sea, making it one of the world's longest navigable subterranean rivers. This subterranean river is a significant landmark due to its magnificent rock formations, vast chambers, and the rich, unique ecosystem it supports both inside and outside the cave.

The park's history is deeply rooted in local culture, with the indigenous Tagbanua people considering the area sacred. They have historically relied on its natural resources for their sustenance, and their cultural traditions and management practices have been indispensable in preserving the park's ecological balance. The park has become an important site for scientific research and education, contributing to greater understanding and conservation of karst landscapes and subterranean ecosystems.

Geographically, the park is situated at approximately 10.2° N latitude and 118.9° E longitude. The climate is tropical, characterized by high humidity and a temperature range of 22°C to 32°C. The wet season runs from June to November, while the dry season spans December to May, offering favorable conditions for tourism during the latter.

Aside from the awe-inspiring underground river, notable landmarks within the park include a rich diversity of flora and fauna. It is home to over 800 plant species, 165 bird species, 30 mammal species, and various reptiles. Among them are threatened species like the Palawan hornbill and the Philippine long-tailed macaque.

The park is a focal point for environmental festivals, such as the local Ecotourism Festival which promotes sustainable tourism practices and environmental awareness. These events highlight the importance of conservation efforts, inviting local and international visitors to participate in preserving the area's natural wonders.

An interesting trivia about the park is its feature in the New7Wonders of Nature campaign, where it was officially recognized in 2012. This accolade has furthered its international acclaim as a must-see destination for nature lovers and adventure seekers.
