A Journey Through the Heart of the Heritage
If you are an avid explorer yearning to immerse yourself in untouched nature, the Ao Ech – Viet Hai trekking route is the perfect choice at Cat Ba National Park. More than just a trail, this is a unique journey through the very heart of a World Biosphere Reserve.
The extraordinary highlight of this trek is Ao Ech (Frog Pond):
In the summer, Ao Ech is a serene freshwater pond hidden deep within the limestone mountains, creating a poetic and tranquil landscape. However, during the dry season, the water gradually recedes to reveal an extraordinary forest floor. You can walk across this surface without sinking, even feeling a slight bounce and the cool dampness of the soil beneath your feet—a truly fascinating and one-of-a-kind experience.
Continuing the journey, visitors will navigate through dense canopies, traverse magnificent limestone valleys, and explore a highly diverse ecosystem. The trek concludes at the ancient Viet Hai fishing village, a secluded settlement isolated from the outside world, where traditional culture remains beautifully intact.
This route not only tests your physical endurance but also provides a rare opportunity to admire the pristine beauty of the National Park, witness the magical seasonal transformations of nature, and gain a deeper understanding of the heritage values we are collectively conserving.
