Archaeologists and divers have recently discovered an underwater stone arch in Ly Son district in the central province of Quang Ngai, adding it to the list of must-visit places in the island district.    

The arch is believed to have been formed by four volcanoes 250 million years ago. It belongs to An Vinh islet and is approximately 1.5km from the shore. 

Travel agencies have begun deploying scuba diving tours to the stone arch, offering visitors a chance to enjoy the stunning underwater beauty. 

According to Phan Tran Tan Tai, tour guide of the Volcano Ly Son Dive Centre, visitors will be equipped with with the necessary scuba gear, as well as a wetsuit and diving mask. He also said those who are pregnant or have hypertension or diabetes should not join the tour. 

According to divers, the 100m underwater arch is about eight times longer than the onshore one, which is also located on Ly Son island.

The arch surface is covered with abundant colourful marine creatures, enchanting visitors to the scene. 

It is the first time Le Tan, a visitor from Quang Ngai city, visited the underwater stone arch. 

“It was amazing to see all the sea creatures,” Tan exclaimed, adding that he was carefully guided by the professional divers. 

“It is not difficult at all, even for those who are not experienced divers,” Tan said.

The arch’s highest point is 5m from the water surface, and 13m at the lowest point. The deeper visitors dive, the clearer they can see the marine creatures.

It is estimated that hundreds of tourists have already had the pleasure of discovering the arch through the diving tour, launched two months ago.

Nguyen Thi Thuy Trang, a visitor from Kon Tum province found it wonderful to enjoy the natural beauty. 

“The colourful coral reefs and lively fish make me to want to stay there forever. The underwater world is even more beautiful than I had seen on films,” Trang told Vietnam News Agency reporter.
