Phong Nha-Ke Bang area is noted for its cave and grotto systems as it is composed of 300 caves and grottos, of which only 20 have been surveyed by Vietnamese and British scientists; 17 of these are in located in the Phong Nha area and three in the Ke Bang area. Phong Nha holds several world cave records, as it has the longest underground river, as well as the largest caverns and passageways.

The park derives its name from Phong Nha cave, the most beautiful of all, containing many fascinating rock formations, and Ke Bang forest. The plateau on which the park is situated is probably one of the finest and most distinctive examples of a complex karst landform in Southeast Asia.

There are several heritage and splendid sights in Vietnam. Especially, Da Nang is one of the most popular place for both Vietnamese and foreign tourist. Da Nang includes sea, Son Tra island, mountain and beautiful landscape. There are a lot of interesting places such as: Asia entertainment park, Ba Na hill, Hoi An ancient town, My Khe beach, museum of art as well as famous bridges. The city is well known for its fresh atmosphere, friendly people and security. The weather is glorious all the year and it brings this city many delicacies from sea and perfect living condition for people, specifically the elder. Visiting Da Nang, I am really impressed by Ba Na hill containing longest cable car from land to the top of the mountain. It is an unforgettable experience for visitors to observe breathtaking sight and picturesque scene. Beside, the beaches have long golden sand, deep blue sea in addition huge bunches of fresh coconut. Tourist has a chance to relax, enjoy the peace and nature, play aquatic sport. Moreover, the city has many big bridges like: Dragon bridge, Quay bridge and a large outdoor entertainment named Asia park. Additionally, there are a lot of delicious typical dishes such as: Quang noodle, xeo cake, pork pan-cake and others. Da Nang is preserved for its natural beauty; therefore, there is an increasing number of tourists come here. Consequently, it leads to polluted environment, natural damage and other social problem. However, the security of the city is good that there is no street robbery. Hence, Da Nang is voted to be one of the most worth-living cities in Vietnam. In the future, I hope Da Nang will develop and become more popular over the world.
