Where Is Ha Long Bay, Vietnam? Your Guide To Its Location, Scale, And Gateways

When you begin to dream of a trip to our beautiful country, we are almost certain that the first and most powerful image that comes to your mind is the magnificent, emerald-green waters and the thousands of majestic limestone islands of Ha Long Bay. But one of the first and most practical questions you will ask is, “Where is Ha Long Bay in Vietnam, and how do I get there?” Understanding the geography of this incredible UNESCO World Heritage site is the key to planning the perfect, seamless, and unforgettable journey. As your expert guide at Vietnam Story, we have created this comprehensive guide to give you a clear and simple understanding of Ha Long Bay’s exact location, its incredible scale, and the best and most efficient ways to reach it, with special tips curated just for our Indian travelers.

The exact location and the incredible geographical scale of the Bay

Ha Long Bay is proudly anchored in the Quang Ninh Province in the beautiful Northeastern region of Vietnam. It is a stunning and vast bay that lies along the northwest coast of the Gulf of Tonkin. The sheer size and scale of the bay are truly breathtaking. Let’s look at the numbers.

The entire bay spans a massive 1,553 square kilometers (which is roughly seven times the size of Hanoi’s city center) and has a beautiful 120km coastline that stretches from the Yen Hung District all the way to Van Don Island. The bay is famous for its 1,969 majestic limestone karsts that rise dramatically from the sea.

Within this vast bay, there is a strictly protected area of 434 square kilometers that contains 775 of the most beautiful islands. This Protected UNESCO core zone is bound by Dau Go Island to the west, Ba Ham Lake to the south, and Cong Tay Island to the east.

In 2023, UNESCO officially expanded the World Heritage site to include the pristine and beautiful Cat Ba Archipelago in the neighboring province of Hai Phong. This has made the Ha Long – Cat Ba area Vietnam’s very first inter-provincial World Heritage site, recognizing its immense and interconnected natural value.

How you can get to the Bay

For most of our travelers coming from major Indian cities like Delhi or Mumbai, our nation’s capital, Hanoi, serves as the primary and most convenient gateway to Ha Long Bay. Thanks to modern infrastructure, the journey is now faster and more comfortable than ever before. The distance from Hanoi covers approximately 165 km.

Traveling by Land (via the new Highway 5B)

Private car: This is the most comfortable and direct option, especially for families and groups. The journey now takes only a pleasant 2 to 2.5 hours.
Luxury limousine shuttle: This is a very popular and comfortable shared-van option that takes about 2.5 to 3 hours and will often pick you up directly from your hotel in the Hanoi Old Quarter.

Traveling by Air

Van Don International Airport (VDO): This is the closest airport to the bay. If you are flying in from another Vietnamese city like Da Nang or Ho Chi Minh City, this is a fantastic choice, as it is only a 45–60 minute drive from the bay.

Van Don International Airport has top-notch infrastructure

The seaplane: For a truly unforgettable and luxurious experience, you can take a 45-minute seaplane flight from Hanoi’s Noi Bai Airport that lands directly on the water at the Tuan Chau marina.

The all-important gateway ports

Tuan Chau International Marina: This is the main departure point for 90% of the luxurious overnight cruises.
Ha Long International Cruise Port (in Bai Chay): This is a newer, very modern terminal located near the Ha Long Cable Car and the Sun World theme park.
Ao Tien Port (in Van Don): This has become the new hub for the more remote “eco-escapes” to beautiful islands like Co To.

Rare insights: The depths of the Bay and its weather patterns

Beyond the surface beauty, the bay has some fascinating hidden characteristics. Let’s look at the science and the local secrets of the bay’s weather.

While the bay has a gentle average depth of about 5 – 10 meters, the main navigation channels that your cruise ship will follow can reach depths of 15 – 29 meters. In some of the more remote offshore areas near the Bai Tu Long border, the bay can be as deep as 30 meters.

If you visit in January, you will experience our high humidity (75 – 85%) and the beautiful morning mist. This creates a magical, “dreamlike” fog that wraps around the karst islands, a phenomenon that we locals romantically call “the dragon’s breath.”

For the best weather, Vietnamstory.in highly recommends you avoid the months of July and August. This is our peak rainy season, and we can see over 300mm of rain. On the other hand, January is our driest month (with only about 15mm of rain), making it ideal for clear photography without the risk of storms.
