Top 5 cave of Phong Nha-Ke Bang National Park, Vietnam
Phong Nha-Ke Bang National Park is known for its caves. While there are a lot of tours and caves in the region, there are only 4 most visited caves in Phong Nha that are suitable for all ages and physical level: The Phong Nha Cave, the Tien Son Cave close to it, Paradise Cave and the Dark Cave. All the other caves would require a much higher fee and pre-booking. So unless you are a cave enthusiast, you would unlikely visit them.
