Phong Nha-Ke Bang ranked second in Lonely Planet's “Top experiences in Vietnam” Phong Nha-Ke Bang National Park has come in second in a list of the “Top experiences in Vietnam”, according to Lonely Planet, a renowned travel publication. Phong Nha-Ke Bang National Park is home to the largest cave system in the world Lonely Planet describes Phong Nha-Ke Bang National Park as the remarkable world natural heritage. The site was first honored by the UNESCO in 2003. The second UNESCO recognition of Phong Nha-Ke Bang National Park was announced in 2015. “The National Park contains the oldest karst mountains in Asia, formed approximately 400 million years ago. Riddled with hundreds of cave systems – many of extraordinary scale and length – and spectacular underground rivers, Phong Nha is a speleologists’ heaven on earth. The Phong Nha region is changing fast. Son Trach village (population 3000) is the main centre, with an ATM, a growing range of accommodation and eating options, and improving transport links with other parts of central Vietnam. The caves are the region's absolute highlights, but the above-ground attractions of forest trekking, the area's war history, and rural mountain biking means it deserves a stay of around three days”, the travel site said. “Top experiences in Vietnam” voted by Lonely Planet's include Hoi An, Phong Nha-Ke Bang National Park, Ha Long Bay, Hue, HCM City, Ha Giang province, Cat Tien National Park, Bac Ha markets, Phu Quoc island, Hanoi, Con Dao island, Ba Be National Park, Sapa trekking, Demilitarized Zone (DMZ) and Mui Ne.
