1. Exploring Thuy Cung Cave - The Jade Palace in Sinh Ton Valley

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.

2. Trekking journey to Thuy Cung Cave

To conquer Thuy Cung Cave, you will begin your journey through Survival Valley, a pristine land spanning over 2,000 hectares where nature retains its untouched beauty. The trekking journey starting from 5 km (depending on a 1-day or 2-day 1-night tour) takes you through the Dau Rai primary forest, romantic Tien Stream, and majestic limestone mountain ranges. The highlight is the upstream stream-wading section to reach the back entrance of Nuoc Lan Cave, before arriving at Thuy Cung Cave.

Along the way, you will encounter rare flora and fauna such as Great Hornbills, Edward's Pheasants, or plant species listed in the Red Data Book of Vietnam. The scenery of Survival Valley with lush green meadows, ancient forests, and gurgling streams will make you forget your tiredness, leaving only the feeling of immersing yourself in nature.
