A new cave described as very beautiful and mysterious with a complex series of grottos has been discovered in the northern mountainous province of Bac Kan.

The first cave was found when laborers were building the National Highway 3B near Ang Toong Pass.

The newly-discovered cave is 20 meters deep inside the first cave. All stalactites are still untouched and kept shimmering and shining like stars in the sky.

The first cave is 120 metres long, very spacious and is formed by three caves. The newly-explored one is 350 meters long and formed by five caves. All the walls are blue stone and in some places are mixed with soil and white stone.

The deeper the cave, the more stalactites it has. Illusionary stalactites and stalagmites in diverse size and colors make people believe they are in a lost world. As the wonderful stalactites are like long strips of curtains, patterns on the walls like bas-reliefs and stone pillars like lighting candles. Some strings are 1-2 meters long and look like lianas leaning over someone’s roof.

In some sections there are stalactites overlapping and if you knock on them it sounds like a musical instrument.

Somewhere amongst the rocks are small fresh streams which make the cave look like a water-color painting. The bottom of the cave has no mud and is very clear with stalactite layers like old coins arranged together under the pristine water surface.

The local authorities have alerted Vietnam travel agencies to protect and develop the caves into a tourist destination for Bac Kan Province. They have to make sure locals don’t steal the precious stalactites as they try to keep the caves in their original condition.

Bac Kan is a mountainous province famous for its beautiful landscapes, rich forest and mineral resources.

It also has Ba Be Lake which was recognized as a national historic cultural heritage in 1996 - but it is best known for its miraculous underground caves such as Poung, Tien, Na Phoong, Ba Cua, Son Duong, Nang Tien and Tham Long.
