Bai Tu Long Bay: Top 15 Must-See Attractions & Travel Tips for 2025-2026

The Hidden Paradise of Northern Vietnam: Exploring Bai Tu Long Bay in 2025-2026

Welcome to Bai Tu Long Bay, Vietnam’s best-kept secret and a pristine alternative to the more famous Halong Bay. Located in the northeastern part of the country, this spectacular seascape offers the same breathtaking limestone karsts and emerald waters but with significantly fewer crowds. For travelers seeking tranquility, authentic experiences, and unspoiled natural beauty in 2025, Bai Tu Long Bay delivers an unforgettable journey through one of Southeast Asia’s most stunning landscapes.

Whether you’re planning your first trip to Vietnam or returning to explore beyond the usual tourist destinations, this comprehensive guide will help you discover why Bai Tu Long Bay should be at the top of your travel list for 2025.

Understanding Bai Tu Long Bay: Location and Significance

Nestled in the Gulf of Tonkin, Bai Tu Long Bay extends from the east of Halong Bay to Vietnam’s border with China. Covering approximately 158 square kilometers, this expansive bay contains over 1,600 limestone islands and islets, creating a dramatic seascape that rivals its more famous neighbor.

The name “Bai Tu Long” comes from a Vietnamese legend about a mother dragon and her children who descended to protect Vietnam from invaders. While the dragon mother landed in Halong Bay, her children settled in what is now called Bai Tu Long Bay—”the bay of dragon children.”

What truly sets this area apart is its inclusion in the UNESCO World Heritage designation that it shares with Halong Bay, recognizing the region’s outstanding geological and geomorphological value. Unlike Halong Bay, however, Bai Tu Long maintains a serene atmosphere where nature’s splendor can be appreciated without the distraction of overcrowding.

Why Choose Bai Tu Long Bay Over Halong Bay in 2025?

Pristine Natural Environment

In 2025, Bai Tu Long Bay continues to maintain its ecological integrity through careful tourism management. The water here is noticeably cleaner than in Halong Bay, with visibility reaching up to 5 meters in many areas. Recent environmental protection initiatives have further improved water quality, making it ideal for swimming and snorkeling.

Significantly Fewer Tourists

While Halong Bay receives approximately 7 million visitors annually, Bai Tu Long Bay sees only about 20% of that number. This dramatic difference means you’ll encounter fewer boats (approximately 40 cruises operate here compared to 200+ in Halong Bay) and can enjoy peaceful moments to truly connect with the landscape.

Authentic Cultural Experiences

The floating fishing villages in Bai Tu Long Bay, such as Vung Vieng and Cong Dam, maintain traditional lifestyles that are increasingly rare. With approximately 300 residents, these communities offer genuine insight into a way of life that has existed for generations, largely unchanged by tourism’s influence.

Premium Cruise Experiences

The limited number of operators in Bai Tu Long Bay has encouraged a focus on quality over quantity. Most cruises here offer higher standards of service, more spacious cabins (typically 22-32 square meters compared to 16-24 square meters on standard Halong Bay cruises), and more thoughtfully curated itineraries.

The main beach, Van Chay, extends for 3 kilometers along the island’s western coast.

15. Bai Tho Mountain (Poetry Mountain)

Rising 200 meters above Halong City, this limestone mountain marks the western gateway to Bai Tu Long Bay.
