🎧 Listen to Introduction

The park features spectacular limestone karst landscapes and an underground river. A major feature of the river is that it flows directly into the sea, with the lower reaches partly affected by tides. The area is also an important habitat for biodiversity conservation. The area has a complete "mountain-sea" ecosystem and contains the most important forests in Asia.
