About Phong Nha-Ke Bang National Park
Phong Nha-Ke Bang National Park, a UNESCO World Heritage Site in central Vietnam, protects one of the world's oldest karst landscapes, hiding an extraordinary network of caves that includes Son Doong, the largest cave passage on Earth, big enough to hold entire city blocks within its chambers. The park's dense limestone forest, carved over hundreds of millions of years, also contains hundreds of other caves, many only discovered or explored in recent decades.
While Son Doong requires a demanding, expensive multi-day expedition with limited annual permits, more accessible caves such as Phong Nha Cave and Paradise Cave offer spectacular stalactite and stalagmite formations within easy reach of most visitors, reachable by boat or a short walk. The combination of show-stopping scale, genuine adventure travel and relatively undeveloped jungle scenery makes the park one of Vietnam's premier natural attractions.
