Dubbed "Thuy Cung" (Aquarium) due to its crystal-clear, jade-blue water, Thuy Cung Cave (also known as E Cave) is one of the most beautiful caves in the Phong Nha - Ke Bang complex. Stepping into the cave, you will be overwhelmed by the magnificent stalactite system, pure white rock formations, and silver-shimmering stalagmites, creating a magical wonderland-like atmosphere. In particular, the echo resonating inside the cave whenever you shout sounds like a symphony of nature.
The underground stream inside Thuy Cung Cave is a unique highlight. With a moderate depth, you can swim through the cool water, admiring stalactites from an underwater perspective—a rare experience matched by few other caves. The mystery behind the jade-green hue of the water remains a curiosity for scientists, further adding to the destination's charm.
