Because Mr. Thin (the DMZ guide from the post before) was such a good guy, I accepted his offer to ride along with him to the Phong Nha-Ke Bang National Park. On the back-seat of his trusty Honda C90 (you always find a way to store your huge backpack...) we drove about 150km north-west of Dong Ha to the famous Kast mountain region of Phong Nha.
Phong Nha is not only a protected nature reserve...
