I traved far and set foot on 52 provinces of Vietnam and 48 countries all over the world. The most beautiful, most impressive and most picturesque landscaps are present in my memory. From the famous beautiful beaches to sky high mountains, from traditional local dishes to local languages, etc. All have left deep impression in my mind. However, among impressions and countless landscapes, the beauty of volcanoes always absorb me most, including active or dormant volcanoes. Unlike Philipines and Indonesia, Vietnam has many dormant volcanoes but mainly concentrated at the central and south part of the country. I wish the beauty of volcanoes will be a source to attract many tourists at home and abroad in the coming years.
The most common perception of a volcano is of a conical mountaint, spewing lava and poisonous gases from a crater as its summit. There are many types of volcanoes, and the features of volcanoes are much more complicated. Some volcanoes have rugged peaks formed by lava domes rather than a summit crater, whereas others present landscapes features such as massive plateaus. Nowadays, most of volcanoes in Vietnam are not active and they often evoke not only in my mind but also anyone who likes discovering the secret of volcanoes behind their beauty. The craters, vestiges of volcanoes are found along the length of Vietnam country, especially at the area of central part and south Vietnam. Why are there many regions of central highlands in Vietnam with rich basalt soil where are considered barns of coffee, tea, cocoa and cashew nuts? That is the result of eruptive lava from volcanoes. 
Besides the huge economic benefit came from volcanoes' lava, the crater at central highlands shaped a lot of beautiful sites - a national property. Pleiku which is a town in central highland of Vietnam, located beside 15 dormant volcanoes. From the influence of lava millions years ago, the beautiful sites such as Bien Ho or Gia Long waterfall are created and today they become the famous landscapes.
Vietnam has many "stepping stone" rock beaches, among them that of Da Dia in Phu Yen province is considered the best and the most beautiful. The area consists of black or yellow rock columns, which are half-undersea. The rock have a hexagonal, square or round top, just right for stepping on. Seen from a far, the area looks like a giant honey comb, with the rocks the comb's cells. The scientists say the rocks are balsatic, created during the volcanic eruptions about 200 million years ago. When volcanoes erupted, the lava flowed into the sea where it "froze", and the whole mass of lava cracked. Most of the rocks cracked vertically and this created upright or oplique columns. Horizontally - cut rocks formed round and polygon that looks like stacks of dishes.
Da Dia was certified as a national scenic spot in 1998 by the Ministry of Culture and Information. The road to the sea is not good but hardy vehicles can get close to it. The scenery remains pristine so there are no restaurants, guesthouses or hotels there. The best time to visit is from March to August.
