Inside mysterious 'floating' lake discovered in Vietnam's cave kingdom
A ‘floating’ lake found at Thung Cave in Phong Nha-Ke Bang National Park’s top global cave system in central Vietnam boasts surreal beauty and will immediately be developed for tourism.
In early May, Jungle Boss Tours, an adventure travel company that exclusively runs cave exploration tours in the world-renowned cave systems of central Vietnam's Quang Binh Province, announced the discovery of a mysterious lake located in a sub-branch of Thung Cave of of Thoong Valley.

The lake is located around one kilometer from the entrance of the cave, in one of the most pristine caverns in the area. It is situated deep within a strictly protected zone of the national park.
Le Luu Dung, director of the company, said that the expedition team accidentally found the lake during a regular inspection of cave safety systems while monitoring underground river water levels inside the cave.
The lake's surface is about 15 meters higher than the main underground river branch inside the cave, making it look to its discoverers like it was "floating" on the cave wall.
About a week after discovering the lake, the expedition team returned and discovered the lake's water level had dropped 2 meters.
Dung said the lake water level has now recovered, but the cause of the receding water had not yet been determined.
"In June, the expedition team will survey this lake closely," Dung said.
Dung said the discovery of the lake would bring new experiences to visitors of Quang Binh, known as Vietnam’s "cave kingdom."
Every year, new discoveries are made in the caves and ecosystems of the Quang Binh’s vast underground and mountain network.
The newly-discovered lake reflects a transparent emerald, or “greenish” color, and has been tentatively named Lo Lung (floating) lake due to its uniquely subtle and disarming appearance and location.
Tours into the valley have been allowed by provincial authorities since early last year.
The chain of cave systems in Thoong Valley includes Tron Cave, Hung Cave, Thung Cave, Hung Thoong Stream, and Ma Da Lake.
A cave with magnificent beauty has been discovered in the central province of Quang Tri.
The South China Morning Post (SCMP) of Hong Kong (China) has recently honoured Son Doong cave in Vietnam's central province of Quang Binh as one of the seven most beautiful underground attractions in the world.
