>> Ghenh Da Dia

With natural stones, strangely structured rocks, columns or obliques of frozen mineral flows, Ghenh Da Dia (Rapids of Stone Plates) is considered as a masterpiece of stone gifted by the nature.






Located in An Ninh Dong Commune , Tuy An District, Phu Yen Province, Ghenh Da Dia is strangely structured rocks include large upright stones equally arranged in a star pattern. Being a riddle of nature, like a giant jigsaw, the rapids is irritatingly made of the same shaped pieces, and forms a solidified structure that has proved more than just a curiosity for thousands.

A strange geological phenomenon

Millions of years ago, during volcano eruption, mineral flows melting will be frozen when they encounter water and then the solid breaks into columns or obliques. That created the beautiful landscape of Ghenh Da Dia for the present time. Time over time, the landscape is rearranged as an artistic work by the hand of nature. Ghenh Da Dia is about 1km2 large, half in the sea and half above sea level.

Looking down on it, visitors often liken it to a gigantic beehive, others as a pile of stone plates. For despite a lengthy series of historical, archeological and scientific probes of the cliff’s square kilometer, its formation remains a mystery.

The stones in Ghenh Da Dia are bazan stones of dark black and light yellow. There exists large stones of tons and small stones with different shapes: round, pentagon, polygon and so on. The stones take the right column or a settlement close to each other like disks arranged on couples together. Even counting the stone columns has failed to yield an exact figure as exhausted researchers usually call a halt at around 35,000. The stones are 60-80cm in visible height and 20-30cm across and cluster round a small fresh water pond that is fed by underground rivers and never dries up.

And a wild beauty...

In Ghenh Da Dia, there only remains the unique scenery of the sea and stones, so everything is still primary, environment is so pure, air is fresh and comfortable.





Besides Ghenh Da Dia is Bang beach, with rocks “lie” quiet under the shadow of trees. This is quite ideal for relaxation, camping and extra activities. Ghenh Da Dia and the beach are closed with a famous tourist attraction which is "Hòn đá lực lượng" - a deep and wide grotto that saves the legendary people in a war period. In the war, our main force sheltered in the cave at night, waiting to the day to go on a sortie and dealt enemy thunderstruck blows.

Visiting Ghenh Da Dia, you have a chance to view many species of marine creatures, especially “Mứt” seaweed - a type of kelp which is salty and sticks to the stones, looking like a network.

Have been listed as a National Heritage Site by the Ministry of Culture and Information, Ghenh Da Dia is a potential tourist attraction to both domestic and foreign visitors. And a visit to the rapids, you will be certainly worth it...
Close to Hoi An town, Cu Lao Cham really cherishes high potential for tourism development.

>> Son Dong, the world's largest cave

Son Dong, a cave belongs to the Phong Nha-Ke Bang grotto system in central Quang Binh Province, has been discovered to be the biggest in the world.






Son Doong cave, discovered by a local 18 years ago, is more than 200 meters wide, 150 meters high, and at least 6.5 kilometers long, though the explorers said they were unable to explore it fully. Bristish explorers have recently discovered that So Dong is much larger than the world’s biggest known cave.

The biggest section of Son Dong is five kilometers in length, 200 meters high and 150 meters wide, said Howard Limbirt of the British Cave Research Association team searching the area April 10-14, 2009.

Son Dong is much larger than Deer Cave in Malaysia, currently considered the world’s largest, an explorer said (Deer is 90 meters wide, 100 meters high and 2 kilometers long). The Son Doong cave has replaced to take pole position as the world’s largest cave.

The Son Dong is situated below another cave in Phong Nha-Ke Bang, though its entry passage is very difficult to traverse. The exploration team said they had set foot on just 6.5 kilometers along the cave, as there is a large amount of fast flowing water inside Son Dong. It takes explorers six hours of walking through a 10 kilometer long forest path from Truong Son Highway to reach the mouth of Son Dong cave. The explorer added that the Quang Binh cave has beautiful stalactites and stalagmites that are not seen anywhere else.

Phong Nha-Ke Bang grotto system belongs to the Phong Nha-Ke Bang National Park. It is a limestone region of 2,000 square kilometers in Vietnam and borders another limestone area in Hin Nammo in Laos. When describing the newly-discovered cave, the team’s spokesman, Haward Limbirt, said that it was a thing of overwhelming beauty and grandeur.

He added that each grotto has its own beauty, but he is impressed by Ca Xai. This cave is near the Vietnam-Laos border. It is very deep and has a big lake inside. Explorers measured the depth of this lake, but they had only 200m of rope and the end didn’t reach the lake bed.

The British team suggested to the local authorities not to develop Son Doong Cave as a tourism site immediately to preserve its natural beauty.
