Are you seeking an off-the-beaten-path destination in Vietnam that offers pristine natural beauty without the tourist crowds? Look no further than Bai Tu Long National Park, the lesser-known sister of Ha Long Bay that will take your breath away with its untouched landscapes and rich biodiversity.
A Natural Wonder Hidden in Plain Sight
Established in 2001, Bai Tu Long National Park is a protected area spanning over 15,783 hectares, including both land and water surface. This magnificent park encompasses hundreds of islands, islets, and limestone karsts rising dramatically from emerald waters, creating a landscape that seems almost too perfect to be real.
Location & How to Get There
Situated in the northeast region of Vietnam, Bai Tu Long Bay National Park lies within Quang Ninh Province, approximately 200 kilometers east of Hanoi. The park stretches from Van Don District to the Chinese border, making it easily accessible yet maintaining its pristine character. Most visitors reach the park via Van Don International Airport or by taking a scenic 4-hour drive from Hanoi.

Nature’s Masterpiece: A Symphony of Land and Sea
What makes Bai Tu Long truly special is its remarkable seascape. Imagine sailing through calm, crystal-clear waters surrounded by thousands of limestone islands covered in lush vegetation. The bay’s scattered limestone karsts create a mystical atmosphere, especially during sunrise and sunset when the golden light paints the landscape in ethereal hues.
The limestone formations here, shaped by millions of years of natural processes, tell a fascinating geological story. Some islands rise dramatically like ancient fortresses, while others appear to float gently on the water’s surface, creating a mesmerizing vista that photographers dream of capturing.
A Haven of Biodiversity
The park’s ecosystem is a complex tapestry of marine and terrestrial life. The area hosts:
- Over 1,000 species of marine animals
- 40+ species of rare and endangered wildlife
- 100+ varieties of coral

- Diverse seagrass beds
This rich biodiversity makes the park a crucial conservation area and an excellent destination for nature enthusiasts and researchers alike.
