Accordingly, since Son Doong Cave began to be explored on August 1, 2013, 8,552 visitors have conquered this largest cave in the world . Vietnam still leads with 3,293 visitors, followed by the United States with 2,271.
Total revenue since its launch is $25.5 million, and the tour operator has contributed $5 million to Phong Nha-Ke Bang National Park, creating direct jobs for 130 local people and hundreds of indirect jobs.
In 2026, with 1,000 visitors allowed to explore the cave with the permission of the former Quang Binh province, the number is sufficient. Tourists are ready to conquer the challenge and enjoy incredibly exciting experiences at Son Doong Cave by the end of January 2026. In fact, Son Doong Cave tours are fully booked until the end of 2027.
The fact that tours to Son Doong Cave have been fully booked for so long has created a "scarcity" and "desire" among adventure tourism enthusiasts worldwide. This also presents an opportunity for other, less adventurous tours in the Phong Nha-Ke Bang National Park World Heritage Site to attract more visitors.
According to the Department of Culture, Sports and Tourism of Quang Tri province, adventure tourism in Phong Nha-Ke Bang has two main segments. Besides the popular experiential tourism products, such as visiting the beauty of the caves and enjoying recreational activities at Phong Nha Cave and Thien Duong Cave, the segment with a higher level of adventure and many new and exciting discoveries requires tourists to have higher spending power, good health, and more time.
According to statistics, Phong Nha-Ke Bang National Park has now become a major cave exploration tourism center in the world, attracting nearly 50,000 visitors annually.
