Planning a Ha Long Bay Cruise: FAQs & Everything you Need to Know

Located in northeastern Vietnam, Ha Long Bay is one of the country’s most iconic natural wonders and a UNESCO World Heritage Site. The bay is home to thousands of limestone islands and islets, sculpted over millions of years into the dramatic karst landscape that has become synonymous with Vietnam. Whether shrouded in mist or glowing in the afternoon sun, its otherworldly scenery has captivated travellers for decades, making a cruise through the bay a highlight of most Vietnam itineraries.

Statistics and photographs can only tell you so much.

What surprised me most was the sheer sense of scale. The limestone islands seem to rise almost vertically from the emerald-green water, and no matter how many hours we spent cruising between them, the scenery never became repetitive. Some moments felt dramatic and cinematic, while others were unexpectedly peaceful. It is one of those rare places that somehow manages to look even better in real life than it does in photographs.

All in all, I think that most travellers won’t need convincing about visiting Ha Long Bay.

However, there are a few common questions that seem to come up time and again when people are planning a visit. In this post, I’ll tackle them one by one.

HA LONG BAY FAQs: PLANNING YOUR TRIP

IS HA LONG BAY TOO SIMILAR TO NINH BINH OR PHANG NGA BAY?

Ha Long Bay was, for me, my first visit to a landscape with karst limestone formations. Since then, I have also visited Ninh Binh (straight after Ha Long Bay actually) as well as Phang Nga Bay (the James Bond Islands) on a different trip to Thailand. Did I find them similar? In a general sense, yes, they all feature spectacular karst limestone scenery. Did I feel that I had been there, done that? Absolutely not.

Even if I had visited Ha Long Bay last, after Ninh Binh or Phang Nga Bay, my opinion would remain unchanged. I never get tired of awe-inspiring landscapes. Do you? 

Furthermore, the geology may be similar, but the experience couldn’t be more different. Ninh Binh is explored by rowing through rivers and rice fields beneath towering cliffs, while Phang Nga Bay is typically experienced as a fast-paced day trip.

Ha Long Bay, on the other hand, is all about slowing down and having enough time to soak it all in. Sleeping on the water, watching the scenery drift past from the deck, and waking up surrounded by those limestone islands made the whole experience feel completely unique. Our wonderful experience aboard the Paradise Elegance made it all even more effortless and comfortable, and I am not even a cruise person, at least not yet (maybe that bug bites you a bit later in life, we’ll see!).

Regardless of the cruise itself, the landscape of Ha Long Bay alone is enough to make you stop and say, ‘WOW’. How often do you get to say that?

WHY DID WE CHOOSE HA LONG BAY OVER BAI TU LONG BAY & LAN HA BAY?

While planning our trip, I quickly discovered that many cruises don’t actually visit Ha Long Bay itself, instead sail around neighbouring Lan Ha Bay or Bai Tu Long Bay. These are often promoted as quieter alternatives, offering similar scenery with fewer boats.

Why did I choose Ha Long Bay over the others? Simply because it is generally considered the most spectacular of the three. You might think that’s a little superficial, but for me, that was reason enough. When visiting somewhere I’d dreamed of for years, I wanted to experience the ‘original’, the iconic landscape that had originally inspired my trip.

Looking back, I have absolutely no regrets.

WHAT IS THE BEST WAY TO VISIT HA LONG BAY?

Hanoi, Vietnam’s bustling capital, is the main starting point for most trips, as it offers the closest major international airport and direct road connections to the coast. From both Hanoi’s Old Quarter and Noi Bai International Airport, the journey to Ha Long Bay takes approximately 2.5 to 3 hours by road.

There are three main options when planning your visit to Ha Long Bay:

• If you’re short on time, you can join a day trip from Hanoi, although you’ll spend almost as much time travelling as you do on the water.
• The second option is an overnight cruise, allowing you to experience both sunset and sunrise over the bay. From all the blogs and Reddit discussions I read while planning our trip, this seemed to be the most popular choice.
• Lastly, there are two-night cruises, which offer a more relaxed itinerary with extra time to explore quieter corners of the bay while also enjoying the facilities on board.

WHY DID WE CHOOSE A 3-DAY 2-NIGHT CRUISE AROUND HA LONG BAY?

Personally, I had been looking forward to visiting Ha Long Bay for so long that choosing the two-night (three-day) cruise was a no-brainer.

Generally, my husband and I tend to overthink and overanalyse every aspect of our travel itineraries. This decision, however, barely required a discussion. The more nights we could spend on a beautiful boat cruising through such a spectacular landscape, the better.

For a once-in-a-lifetime experience like this, we’d rather get bored (we didn’t) than come away wishing we had more time.

HOW MANY NIGHTS SHOULD YOU SPEND IN HA LONG BAY?

Looking back, I’m really glad that we chose the longest cruise available. No regrets here. If visiting Ha Long Bay is something you’ve been dreaming about for years, as it was for us, I’d wholeheartedly recommend the two-night cruise.

I share our full Ha Long Bay three-day, two-night itinerary as well as my impressions of our ship, the Paradise Elegance, on my Ha Long Bay: The Journey that Surpassed Every Expectation post (coming soon). Have a read, to see exactly why we loved our time in Ha Long Bay so much, and whether that’s something you would enjoy too.

The benefits of a two-night cruise…

In a nutshell, a longer cruise gives you more time to explore different corners of the bay while also allowing you to slow down and fully appreciate both the spectacular scenery and the joy of cruising itself.

The real benefit, at least for our three-day, two-night cruise on the Paradise Elegance, is that we gained a full day in the middle, allowing us to explore farther into the bay and into quieter areas. Time-wise, we also appreciated that the itinerary was more relaxed and we didn’t have to squeeze all the major excursions into the afternoon after boarding and the morning before disembarking.

If you are travelling aboard a luxury vessel, like we did, you’ll also have more time to enjoy the onboard amenities and activities, whether that’s joining a sunrise Tai Chi session, kayaking or simply relaxing on deck.

…VS the benefits of a one-night cruise or daytrip

However, if cruising doesn’t really resonate with you, or you’re travelling on a tighter budget, a one-night cruise should still be enough to experience the breathtaking scenery and understand why Ha Long Bay has earned its worldwide reputation.

As for the day trip, I would only consider it if you’re visiting Hanoi for another reason -perhaps a business trip or a wedding- and trying to fit Ha Long Bay into an itinerary you have little control over. Otherwise, why impose such a frenetic pace on an experience that is best enjoyed slowly?

HA LONG BAY FAQs: PRACTICAL INFORMATION

WAS HA LONG BAY CROWDED?

Honestly, I didn’t find Ha Long Bay too crowded.

During our visit, yes, Ha Long Bay was a bit busy, we were definitely not alone. However, at no point did I feel uncomfortable or annoyed. We didn’t have to join any ridiculous queues to take photos and had plenty of serene moments even at the busiest locations.

I’m not sure whether this had something to do with the fact that we visited in September. This is generally a quieter period for international tourism, perhaps because it falls towards the end of northern Vietnam’s rainy season and there is still a risk of unsettled weather. We were fortunate to enjoy very good conditions, but perhaps the timing also helped us avoid the largest crowds. That’s only a theory, though, so don’t quote me on that!

Anyway, by sharing my experience, I am not implying that the people saying that Ha Long Bay was crowded are wrong or are lying (though many people on social media tend to exaggerate). At the end of the day, very few visitors can confidently tell you what conditions are normally like based on a single trip. Unless someone visits regularly, their experience -mine included- is only a snapshot in time.

HOW CAN YOU ENJOY HA LONG BAY DESPITE ANY CROWDS?

From all of my travel experiences, I would recommend three things to decrease your chances of encountering busy conditions and have a great time no matter what. Most of them are common sense really, but here they are.

Firstly, as with most popular destinations worldwide, visiting during school holidays (summer mostly) or Christmas would, unsurprisingly, be more challenging in terms of crowds. Avoid those periods if you can. I would also consider avoiding Chinese New Year, as Vietnam attracts a lot of Chinese travellers. Similarly, it’s worth checking the dates for Tết, the Vietnamese Lunar New Year, as holiday travel can affect demand, availability and visitor numbers.

Secondly, opt for a cruise on a spacious ship with plenty of communal areas relative to the number of passengers. You might have to splurge a little bit more to achieve this, but if the bay happens to be crowded, hopping on a comfortable ship after visiting a busy location will definitely provide a much needed recovery space.

Thirdly, adjust your expectations. All you can wish for when visiting one of the most celebrated natural wonders in the world, is that it is not extremely busy. Accept that there will be other people around when you will be visiting one the most beautiful and fairly accessible places in the world. Try to wake up early or stay up late to enjoy silence and solitude.

At the end of the day, popular places are popular for a reason, and greater access to travel is something worth celebrating. Think glass half full, have a laugh watching other people strike silly poses for photos, and be a little more patient than usual.

CAN YOU SWIM IN HA LONG BAY & IS IT POLLUTED?

During our time there, I wondered whether it was safe to swim in Ha Long Bay, so I asked the crew. They told us that the water quality wasn’t ideal and discouraged us from swimming. Having said that, the water was not visibly dirty, nor did we see much rubbish floating around other than the occasional piece here and there. One of the activities included in our itinerary was kayaking, and at no point did I feel uncomfortable being on the water.

On the flip side, I have read comments online mentioning rubbish in the bay, and I can’t help but wonder whether that depends on the currents, wind or recent rainfall. So, your mileage may vary.

In any case, Ha Long Bay lies relatively close to Hanoi and is surrounded by a region with considerable industrial activity. It’s, therefore, not surprising that the water isn’t quite as pristine as one would hope.

IS A HA LONG BAY CRUISE SMOOTH?

During our cruise, the water was exceptionally calm. We barely felt the ship moving, either while sailing through the bay or when anchored overnight. In fact, if you’re worried about seasickness, Ha Long Bay felt very different from an open-sea cruise.

The bay is relatively sheltered by its thousands of limestone islands and islets, which generally makes for calm cruising conditions. Of course, weather conditions can vary, and severe storms or typhoons may cause cruises to be delayed, altered or cancelled altogether. However, based on our experience, the journey was remarkably smooth from beginning to end.

FINAL THOUGHTS

I have written two posts about my Ha Long Bay experience; there’s this post you have just read, with the FAQs, and my other post where I present my itinerary and impressions from our three-day, two-night Paradise Elegance cruise (coming soon). You may notice that, in neither post, do I entertain the question: ‘Is Ha Long Bay worth it?’

For me, yes, of course Ha Long Bay is worth it (whatever ‘it’ is)! I believe that most travellers wishing to experience the beauty, and multifaceted reality of modern life in Vietnam will feel the same way.

As always, in this blog, I believe that travellers should visit the famous places and the lesser known places. Do it both. There’s fun to be had, and that sense of discovery to be experienced (the one that makes spending six months of savings in two weeks of travel worth it) in both the obvious and the hidden gems.

Visit Ha Long Bay and don’t focus on its (not many) flaws. Focus on what is it that inspires and wows thousands of travellers. Trust me, you will not have to search hard at all.
