Quang Binh province is famous for its caves, incredible mountain scenery, and its sprawling beaches, along with unforgettable hospitality and friendliness. Situated 40 kilometres northwest of its provincial capital and built along the Son River, the small village of Son Trach (also referred to as Phong Nha) is growing to meet the growing number of tourists flocking to explore these underground worlds. First nominated as a UNESCO World Heritage Site in 1998 and recognized as one in 2003, Phong Nha – Ke Bang National Park is truly a marvel of nature. This magnificent land is hidden away in the depths of dense jungles, valleys, karst mountains and the serene rivers of Central Vietnam. The fact that the Phong Nha cave system is home to the world’s biggest cave – Hang Son Doong – is what attracts passionate adventurers worldwide. Besides glorious Hang Son Doong, this region has the most spectacular cave systems in the world.
