Exploring a small part of Phong Nha-Ke Bang National Park in Central Vietnam

August 2019, while traveling 3 weeks in Vietnam and I did explore Phong Nha-Ke Bang National Park, that became in 2003 a Unesco World Heritage Site and is home to 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 great area for taking a small boat (sampan) and explore the stunning landscape of karst mountains, rivers and caves. So that is what I did. Be aware that sitting for about 40 min in a small boat (max. 2 persons) in the hot sun is very tiring. Use suncream and maybe take an umbrella with you! And some drinking water! Following are some photos I took while sitting in the sampan.
