The most spectacular 31-km cave, Thien Duong (Paradise), in the central province of Quang Binh, has opened to the public.
It is the longest cave which has been found in Vietnam so far.
First discovered in 2005 by the British Cave Research Association, Thien Duong Cave lies within the conservation area of Phong Nha – Ke Bang Park.
Thien Duong has been described as "the largest and most beautiful cave in the Phong Nha – Ke Bang area" by British spelunkers. They said that the cave's beauty is reminiscent of an imperial palace.
The Truong Thinh Joint Stock Company has invested around VND98.4 billion (US$5.07 million) in the Thien Duong Cave Project that is expected to draw visitors from all over the world.
The Truong Thinh Joint Stock Company is now in the second phase of exploiting Sun Spa Resort on the Bao Ninh beach, also in Quang Binh Province.
