Halong Bay Overnight Cruise Review

What and where is Halong Bay?

Halong Bay is a UNESCO World Heritage Site in northeastern Vietnam, about 150 km east of Hanoi in the Gulf of Tonkin. It is famous for:

• Around 1,600 limestone karst islands and islets
• Emerald‑green water
• Jungle‑topped rocks, caves and hidden lagoons
• That dreamy “other world” feeling when you are out among the islands

The name Hạ Long means “descending dragon”, from a legend that dragons spat jewels into the sea to form the islands and protect Vietnam from invaders. Standing on the deck of a boat, surrounded by these strange rock formations, it is easy to believe you are in the middle of a myth.

Most visitors reach Halong Bay from Hanoi by road in around 3–4 hours.

The journey from Hanoi to Halong Bay

See my blog on Hanoi City Guide and Train Street for more details on these. 

We left Hanoi after breakfast and drove east, swapping the Old Quarter’s scooters for highways and small towns. On our small group tour, the journey itself included an important stop at a social enterprise and handicrafts centre.

Handicrafts stop: more than just a service station

On the way, we visited an organisation that supports an embroidery and handicrafts workshop staffed by young disabled artisans. Instead of a forgettable service station, we had:

• A chance to watch skilled craftspeople at work
• Beautiful embroidered artworks, textiles and souvenirs
• The opportunity to support a business that offers training and employment to people who might otherwise be excluded from the job market

You do not have to buy anything, but it is hard not to be tempted when you see the quality of the pieces and understand the story behind them. It is a good example of how a responsible tour can turn a routine travel day into something meaningful.

Boarding the junk boat: first impressions

We reached the harbour, checked in and boarded our traditional-style junk boat. “Junk” in this context refers to the classic design of the boat, not its quality. Ours was charming:

• Polished wooden interiors
• A sun deck on top with loungers
• A dining area with big windows
• Cosy cabins with en‑suite bathrooms

We were fortunate in that, as a group, we had the boat to ourselves. This made the whole experience feel more intimate and relaxed.

As we pulled away from the harbour and glided into the bay, the landscape slowly closed in around us: island after island rising from the water, some tiny, some towering, many clad in lush green vegetation. Whatever you have seen in photos, being physically surrounded by these karsts is something else.

Halong Bay expectations vs reality

I had heard plenty of negative comments about Halong Bay before I went:

• “It is overcrowded”
• “The water is dirty”
• “It is a total tourist trap”

Our experience could not have been more different. We had:

• Beautiful weather: blue skies, good visibility, calm seas
• Long stretches where our boat felt like it had the bay almost to itself
• Clean‑looking water where we were able to swim and kayak

Is it completely deserted? No. There are other boats, especially near caves and popular stops. But at several points in our itinerary it felt surprisingly peaceful, and there were times on deck when I looked around and could not see another boat at all.

As with so many famous places, timing, routing and operator choice matter. A thoughtful itinerary and the right season can make all the difference.

Activities on the Halong Bay cruise

An overnight Halong Bay cruise is much more than just sitting on deck and admiring the view (although there is plenty of that too). Here is how our experience unfolded.

A generous lunch on board

Shortly after boarding, we sat down to an excellent lunch in the dining saloon. There were multiple dishes – seafood, vegetables, rice, meat – and it set the tone for the rest of the onboard meals: plentiful, tasty and far better than you might expect from “mass cater for a boat of tourists”.

With full stomachs and a first round of drinks poured, we headed out for the afternoon’s adventures.

Cave visit: slippery steps and hidden chambers

One of our first stops was a limestone cave. We disembarked from the junk onto a smaller boat, then onto a dock, and climbed up towards the cave entrance.

Inside, it was:

• Cool and atmospheric after the heat outside
• Dimly lit, with spotlights picking out stalactites and rock formations
• A little slippery underfoot in places, so handrails and sensible shoes made all the difference

We wound our way through chambers and passages, with the guide pointing out nicknamed rock shapes and explaining how the caves formed. It is not particularly strenuous, but there are steps, and anyone with mobility issues should be prepared for uneven surfaces.

If you enjoy geology, photography or just the idea of a hidden world inside the cliffs, the cave visit is a real highlight.

Kayaking and swimming in the bay

Later, we had the chance to go kayaking. Slipping into a kayak and paddling quietly between the karsts gives you a different perspective entirely:

• You can get close to the rock walls and see the textures and plants
• It is peaceful, especially if your boat anchors in a quieter inlet
• You feel tiny and wonderfully small in this strange landscape

We also swam off a small hidden beach, which felt incredibly special. The water was warm, and there was something slightly surreal about looking back at the boat floating between these towering islands while you bob about in the sea.

If your clients are not confident swimmers or do not want to kayak, they can absolutely stay on deck and enjoy the scenery, but for anyone reasonably mobile, I would encourage taking part. It adds so much to the experience.

Life on deck: sunset, cocktails and karaoke

Back on board, we cleaned up and headed for the sun deck as the light began to soften. This was one of my favourite parts of the whole cruise:

• Watching the sun sink behind the silhouettes of the islands
• Feeling the temperature drop to something pleasantly warm rather than baking
• Nursing a cocktail and chatting with the group as the sky turned pink

A note on drink prices on Halong Bay cruises

One thing I wish we had fully appreciated in advance: drinks on board are not cheap.

A couple of points to be aware of:

• Alcoholic drinks are usually extra and are significantly more expensive than you might pay on land
• On our boat, we discovered only when we got the bill that many of the cocktails had been served as doubles as standard, which bumped the cost up

Neither of these is a reason to avoid the bar altogether, but it is worth:

• Asking how drinks are measured
• Confirming prices in advance
• Letting guests know to expect a higher onboard bar bill than they might at a restaurant in Hanoi

With expectations set, sunset cocktails are still a joy.

The joy (and slight chaos) of karaoke

After dinner came karaoke, and this turned out to be far more fun than any of us expected. Throw a bunch of travellers together on a boat in Halong Bay, add a karaoke machine and some well‑chosen tracks, and you have:

• Terrible singing
• Lots of laughter
• A really effective way of breaking any remaining ice within the group

I will not pretend it was my finest hour vocally, but it was one of the most memorable. By around 10.30 pm the boat was quiet, the bay was calm, and we headed to bed with that lovely, slightly woozy “we’re really here” feeling.

Overnight on the boat: what are the cabins like?

Cabins on Halong Bay cruises vary by operator and price point, but in our case they were:

• Compact but comfortable
• With a proper bed, small bathroom and shower
• Air‑conditioned, which is essential in the warmer months
• Quiet enough to sleep well once the generators settled into a background hum

You are not coming for five‑star hotel rooms here; the luxury is outside, in the views and the experience. That said, I slept well and woke up feeling rested and ready for the early start.

Titop Island: 400+ steps for a world‑class view

The next morning began bright and early, as we were disembarking the boat at around 6.45 am for a climb up Titop Island.

The climb

Titop Island is a steep little peak with a viewpoint at the top. To reach it, you tackle:

• Over 400 steps
• In heat and humidity, even first thing in the morning
• On a path that is well‑maintained but definitely “up, up, up”

It is not a race, and there are places to pause along the way, but I will not sugar‑coat it: you will probably be sweaty and a bit breathless by the time you reach the top.

The reward

The payoff is one of the classic Halong Bay postcard views:

• Islands scattered in every direction
• Junks and cruise boats floating like toys on the water
• The subtly changing colours of sea and sky as the sun rises higher

Every single one of those steps suddenly feels worth it. It is the moment when you really appreciate the scale and beauty of the bay.

After soaking it all in and taking the obligatory photos, we headed back down to the beach, re‑boarded the boat and began cruising slowly back towards the harbour.

Disembarkation and the return to Hanoi

Back on the junk, we had breakfast, watched the karsts recede and chatted through our favourite moments. Then it was time to pack up, settle our bills (remember those cocktails…) and disembark.

The drive back to Hanoi felt shorter somehow. There is something about having been out in the bay, slept on the water and climbed Titop that makes the chaos of the city feel different when you return. You are not just a new arrival now; you have a piece of Vietnam under your skin.

Is an overnight Halong Bay cruise right for you?

In my view, yes, for most travellers it absolutely is, with a few caveats.

Ideal for:

• First‑time visitors to Vietnam who want to see one of the country’s most famous landscapes
• Couples, friends and solo travellers who enjoy being on the water
• Anyone happy with a bit of light activity: steps, kayaking, cave visits
• People who like a social atmosphere on board and do not mind a bit of karaoke

Things to bear in mind:

• There will be some steps and uneven ground, particularly in caves and on Titop
• Drink prices on board are higher than on land; budget accordingly
• Weather can affect visibility and mood, although sometimes mist can be just as magical as sunshine
• If you absolutely hate boats, there is no way around the fact that this is a boat‑based experience

For me, Halong Bay was the point in the trip where it really sank in that I was in Vietnam. The combination of sailing between those other‑worldly islands, clambering through caves, paddling on still water, watching the sun set with a drink in hand and then earning that view at the top of Titop made it one of the standout sections of the tour.

If Halong Bay is on your wish list and you would like to talk through the different styles of overnight cruises, seasons and itinerary options, I would be very happy to help shape a version that fits you perfectly.

Mot, hai, ba, zo – and here is to seeing those limestone islands for yourself soon.
