Phong Nha-Ke Bang: Quang Binh’s Land of Wonders, World Records & Sustainable Tours

A UNESCO-Listed Realm of Natural Marvels

Phong Nha-Ke Bang National Park, nestled in Phong Nha Ward, Quang Tri Province, is Vietnam’s “Kingdom of Caves,” enchanting over 1.5 million visitors annually. Located 50 km northwest of Dong Hoi and 450 km south of Hanoi, this 123,326-hectare karst masterpiece, recognized by UNESCO in 2003 and 2015, holds world records for its colossal caves, including Son Doong—the largest on Earth. With activities costing $3–$3,000 (75,000–75,000,000 VND), it’s a paradise for adventurers, nature enthusiasts, and eco-tourists seeking Quang Binh’s unparalleled wonders.

Beyond its geological feats, Phong Nha-Ke Bang boasts pristine rivers, lush forests, and rare wildlife, all preserved through sustainable tourism practices like guided-only cave access and electric transport, aligning with Quang Tri’s “Green Tourism” initiative. Its tropical climate (dry season: November–April, 18–28°C or 64.4–82.4°F; rainy season: May–October, 24–34°C or 75.2–93.2°F) supports year-round exploration.

Administrative Update

Vietnam’s administrative restructuring has merged Quang Binh into Quang Tri Province, with Quang Binh now a ward under Dong Hoi City. Use “Phong Nha, Quang Tri” for navigation, but “Quang Binh” and “Phong Nha” remain globally iconic for tourism, especially for the national park’s record-breaking caves.

Spanning Bo Trach and Minh Hoa communes, Phong Nha-Ke Bang is one of the world’s largest karst regions, formed over 400 million years ago. Its 104-km cave network, including Son Doong, Phong Nha, and Hang En, holds records for the longest underground rivers, tallest cave entrances, and most spectacular stalactites, as assessed by the British Cave Research Association. With 94% forest cover (84% primary), it shelters 2,934 plant species and 800 vertebrates, many in the IUCN Red List. Sustainable tourism, including limited cave access and local-guided tours, preserves this geological and ecological treasure, making it a global beacon for eco-adventurers.
