I appreciate this article. It's very practical and helpful for anyone who wants to travel to Vietnam.
Rising from the emerald waters off the coast of Quang Ninh province, Halong Bay is a UNESCO World Heritage Site that draws millions of visitors each year - both Vietnamese locals and international travellers. Its hundreds of limestone islands twist into dramatic, mythical shapes that offer extraordinary views from many angles - a sight befitting its name, meaning "lying dragon". Most visitors arrive by boat to take in the scenery, and rightly so. But the bay offers far more than a cruise. Here are 10 things to do that will make your Halong Bay trip truly memorable.

11. Some Quick Facts
1. Cruise Halong Bay on a Day or Overnight Boat Trip
The first, and must-do, activity on any first visit to Halong Bay is to cruise the area by boat. There is a fair share of options for travellers to choose from - from smaller vessels with enough space to enjoy a lunch and some light activities during a day trip, to full-blown cruises with comfortable cabins if you want to spend the night out on the bay. Whichever you choose, the experience of gliding between the limestone karsts with nowhere to be is one you are unlikely to forget. If you are planning to visit during peak season (April-June and September-November), it is worth booking at least a week in advance to secure the best rates.
2. Do Morning Tai Chi on the Cruise Deck
If you decide to go for an overnight cruise on the bay, you can experience a slice of traditional Vietnamese daily life by joining a morning Tai Chi session on the cruise deck. Most cruise operators offer this activity for their guests. The practice is beginner-friendly and gives you a gentle, relaxing start to the day. You will also get to take in the fresh morning air and watch the early sun rise over the karsts before the tropical heat sets in - a genuinely peaceful way to begin a morning in Halong Bay. Sessions are usually held around 6am, so it is worth setting an alarm the night before. It is easy to sleep through, but most guests who make the effort say it was one of their favourite moments of the trip.
3. Join an On-Board Cooking Class
Another enjoyable activity offered by many cruise operators is an on-board cooking class. You will get to see what goes into making the incredible Vietnamese food you have been tasting, with the added satisfaction of making it yourself. Spring rolls are typically the go-to dish - easy, familiar, and fun to assemble - but sometimes squid meatballs, a Halong specialty, are offered as an alternative. Either way, it is a lighthearted and delicious way to spend an afternoon at sea. Do check whether your cruise includes a cooking class before booking, as some operators offer it as a standard activity while others charge extra.
4. Go Squid Fishing After Dark
For something a little different on an overnight cruise, squid fishing after dark is one of those experiences that sounds simple but turns out to be genuinely memorable. Once the sun goes down and the bay quiets, crew members set up rods and bright lights along the side of the boat. The light attracts squids to the surface, and from there it is a matter of patience and a little luck. It is a social, unhurried activity that gives you a real sense of the bay at night, which feels like an entirely different place once the day-trippers have gone home. Most overnight cruise operators include squid fishing as a complimentary evening activity, so check with yours when booking - and if you manage a good catch, some crews will cook it for you on the spot.
5. Kayak Through Limestone Caves
Limestone mountains are not only for viewing from afar. Visitors to Halong Bay can also explore some of their caves by kayak. This activity is usually included for travellers who opt for a cruise on the bay, where the boat stops for an interval of time to allow passengers to take control of their own vessel and see the limestone structures up close and personal. Some of the most popular spots for this activity are Luon Cave, where you paddle through a narrow tunnel into a lagoon ringed by karsts, and Bo Nau Cave, known for its dramatic arched entrance. Although the locations chosen for this activity by tour operators are largely safe, please be mindful of the time and follow all safety measures while on the water. If possible, opt for a morning slot - the light is better, the heat is more bearable, and the caves are less crowded before midday. If kayaking sounds like too much effort, a thuyền nan might be more your speed - a little round bamboo boat steered by a local fisherman, who will do all the work while you enjoy the view.
6. Explore Thien Cung Cave
Aside from the smaller limestone caves explorable by kayak, there are certain caves that you can do a mini-hike through. One of the most popular is Thien Cung Cave, which can be roughly translated as "Heaven Palace Cave". This cave is vast, with solid walkways and staircases so that you can explore it with ease. Limestone eroded by water over thousands of years has formed structures of extraordinary shapes - among them formations resembling Buddha figures and animals. Thien Cung is open daily from 8am to 5pm and entrance is included in most cruise packages, but it is worth checking with your operator beforehand. The interior can be slippery, so wear comfortable, closed-toe shoes.
7. Hike Ti Top Island
Ti Top Island is one of the more secluded and less explored areas of Halong Bay, accessible by boat. It has exotic, relatively untouched scenery with panoramic views from its hilltop and clear water that you can enjoy a nice swim in. The climb to the top involves around 400 steps, so while it is a welcome addition to your step count while on vacation, please be mindful of your fitness level and take breaks as needed. Going early in the morning is the best way to beat both the heat and the crowds - the view at that hour is well worth the effort.
8. Visit a Floating Fishing Village
As one of the highlights of a Halong Bay cruise, travellers can visit the floating fishing villages scattered across the bay. Compared to other floating villages across Vietnam, those in Halong Bay offer incredibly picturesque views as local people go about their daily business against the backdrop of the bay's signature limestone mountains. There are two particularly popular villages accessible from Tuan Chau pier: Cua Van Village, which sits between Halong Bay and Lan Ha Bay and Vung Vieng Village which is closer to Bai Tu Long. Both offer a rare glimpse into a way of life that has remained largely unchanged for generations. These are working communities rather than tourist attractions, so be respectful of residents, follow your guide's instructions, and avoid wandering into private areas.
9. Explore Quang Ninh on Shore
Not every highlight of a Halong Bay trip has to be on the water. Spending a half day exploring Quang Ninh province on shore gives you a very different but equally rewarding perspective on the region. The Quang Ninh Museum is a good starting point - its modern architecture alone is worth seeing, and inside you will find well-curated exhibits on the natural history and cultural heritage of the bay area. From there, the local markets of Ha Long city are worth a visit, where you can browse for fresh seafood, local snacks, and souvenirs at a leisurely pace and interact with the local people. Note that the museum is closed on Mondays, so a morning arrival or departure day is often the most convenient time to fit this in.
10. Watch the Sunrise from the Deck
Of all the things to do on an overnight cruise in Halong Bay, waking up early to watch the sunrise from the deck may be the simplest and the most rewarding. As the mist lifts off the water and the first light catches the tops of the mountains, you get a serene version of Halong Bay that most day-trippers never see. The best vantage point is the top deck of your cruise vessel, and sunrise typically falls between 5:30 and 6am depending on the season - check the night before so you know when to set your alarm. Capture the scene with your camera, but do not forget to put it down for a moment and just take it in.
11. Some Quick Facts
Tourists not familiar with Northern Vietnam's climate should aim to visit Halong Bay between April and June, as the sea is calm and the weather is cool before summer arrives. Getting to Halong Bay is easy and convenient. There are many buses running between Hanoi and Halong (Quang Ninh), so travellers can choose the schedule that suits them best. Budget-wise, a basic day cruise starts from around $30-50 USD, mid-range overnight cruises from $100-200 USD per person and luxury options from $250 USD upwards. Travel insurance that covers water activities is strongly advised.
Halong Bay rewards whatever time and attention you give it. If you only have one day, make it a cruise - but if you can afford to spend a night, you can experience the full spectrum of activities Halong Bay has to offer: cooking class and squid fishing in the evening, Tai Chi at sunrise, then out to the caves, islands and fishing villages as the day unfolds. For those with an extra day to spare, a morning on shore in Quang Ninh rounds the trip off in a way that most visitors never think to do.
