Another interesting Luffy adventure is spelunking! One of the greatest dream of the pirate queen is to conquer an infinite cave in Vietnam. The cave is popularly known as Hang Son Dong. What amazes me is there is a jungle inside this hole of the Earth. A skyscraper and even a 40 story building could fit into this world’s largest cave.
Fast-flowing Rao Thuong River inside
This is so cool!
Hang Son Dong cave is located in Phong Nha-Ke Bang National Park, Bo Trach District, Quang Binh Province, Vietnam. For more information and photos visit National Geographic.
