When I first moved to Ha Long Bay 10 years ago, no one imagined that the city would change like this. I was no exception. A UNESCO World Natural Heritage site, a tourist destination visited by millions, and a bay always filled with fishing boats. I thought that was all there was to Ha Long Bay.
However, starting in late 2025, something began to change. The announcement of the groundbreaking for the VinSpeed high-speed railway and the $18 billion VinHomes Global Gate. In just one year, this region became the stage for Vietnam's largest development project. When I recorded the news of the groundbreaking in the first installment of this series, I had no idea it would solidify into reality so quickly.
This is the final installment of the series. Amidst an abundance of optimism regarding Ha Long Bay's investment value and travel prospects, I write as honestly as possible as someone who has lived here for 10 years. I will discuss what is improving, what concerns me, and what Ha Long Bay means at this very moment.
Investment and Development for the Future of Ha Long Bay: What Is Changing?

The previous three parts can be summarized as follows.
Part 1: VinSpeed begins construction. Once the Hanoi-Quang Ninh section is completed, travel will be possible in the tens of minutes.
Part 2: When transportation infrastructure changes, travel patterns themselves change. Day trips become possible, and the types of travelers who come change.
Part 3: Vinhome Global Gate Ha Long begins construction. A new city with a total area of 4,100 hectares, an investment of $18 billion, and a population of 244,000. The high-speed train terminal is located within the complex.
These three things are happening simultaneously. Each of them represents a significant change on its own, but as the three interlock, the existing balance of Ha Long Bay is being shaken.
What improvements will there be? Accessibility will change decisively. Instead of taking a three-hour bus ride from Hanoi as is currently done, Ha Long Bay will become part of Hanoi's living sphere once connected by high-speed rail. Infrastructure will improve, and medical, educational, and commercial facilities will be upgraded. The living environment will also change as international-standard amenities are introduced within the Vinhome complex. As a resident for 10 years, I welcome this aspect.
What is the concern? The numbers speak for themselves. If 244,000 people enter, the current population of Ha Long Bay will more than double. Water demand, waste, traffic volume, and marine pollution—none of these are trivial concerns. It is currently impossible to know whether the UNESCO World Natural Heritage status can be sustained or whether international environmental standards will be properly observed.
Traveler's Perspective — Now and 5 Years from Now

Let's think from a traveler's perspective.
Currently, most Korean travelers visiting Ha Long Bay come on package tours or cruises. They travel from Hanoi by bus and return by cruise for one night and two days or two nights and three days. This itinerary is the basic grammar of a trip to Ha Long Bay.
This grammar will change once the high-speed rail opens. If day trips become possible, half-day sightseeing packages may increase instead of cruises. If more travelers opt for non-overnight trips, the cruise industry itself could be restructured. How the companies currently operating cruises in Ha Long Bay accept and adapt to these changes will determine the next five years.
The texture of the trip will also change. Currently, two times coexist in Ha Long Bay: the time of the tourist area and the time of the locals. The dawn fish market, the pho shops in the alleys, and the afternoon when fishing boats return. Once a new city housing 244,000 people and a high-speed rail station within a few tens of minutes' travel distance are built, I wonder how much of this local time will remain.
It is not about good or bad, but about becoming something different. Experiencing Ha Long Bay now will certainly be different from experiencing Ha Long Bay in 2030.

Investment and Relocation: A Realistic Perspective

(https://batdongsaninfo.com.vn/tien-do-thi-cong-du-an-vinhomes-global-gate/)
I am writing this honestly for those interested in investing in or relocating to Ha Long Bay. This is not investment advice; it is a sharing of what I have seen and felt as a resident for 10 years.
The optimistic outlook is as follows: Once the high-speed rail is completed and Vinhomes Global Gate is established, Ha Long Bay will function as a residential satellite city for Hanoi. This could usher in an era where Hanoi office workers live in Ha Long Bay and commute to work. Consequently, the population will grow, commercial areas will revitalize, and demand for real estate will increase.
There is also a realistic perspective. The Vietnamese real estate market does not move quickly like Korea's. Regulations and restrictions on foreign ownership are complex, and the market does not react immediately upon the announcement of development plans. If 48,000 new housing units are released simultaneously, it could actually lead to an oversupply relative to demand. Unless one approaches the market from a long-term perspective looking beyond 2030, hasty judgments carry significant risk.
I would like to say this to those considering relocation: Ha Long Bay is currently a great place to live—with its affordable cost of living, beautiful natural environment, and slow pace of life. However, these conditions may change somewhat after 2028. As development progresses, prices will rise, traffic volume will increase, and the foreign community will expand. Coming now may be a different choice than coming five years from now.

So, right now Ha Long Bay is
To put it in just one word, it is like this.
Ha Long Bay is currently on the verge of its most significant transformation. The infrastructure is still inconvenient, and while development has begun, it is not yet complete. This transitional period is, in fact, the most enriching time for travelers. The convenience of a tourist destination and the authentic local character still coexist.
Once the high-speed rail is completed and Vinhome Global Gate is filled, Ha Long Bay will become more convenient, but also more predictable. Even as a resident of 10 years, it is difficult to say for sure how much of the experience remains of mingling with locals at the dawn fish market and walking into any restaurant to eat pho while looking at the sea.
So I say now.
Through a four-part series, we examined the changes the Hanoi-Ha Long High-Speed Railway will bring to this region. I hope the perspective of a local resident has been helpful.
