Why explore Halong Bay
A UNESCO-listed backdrop that takes your breath away
The Halong Bay — also known as Ha Long or Halong Bay — is home to over 1,600 limestone islands and islets set in the turquoise waters of the Gulf of Tonkin. This karst labyrinth, listed as a UNESCO World Heritage site, changes its face throughout the day: dawn cloaks the cliffs in a pearl mist, twilight ignites the contours in amber. The atmosphere, sometimes unreal, is perfect for photos as well as dreamy silences.
The magic of a cruise on the water
The best way to embrace these landscapes is on a cruise. Onboard, you weave between sugarloafs, sail towards spectacular caves (don’t miss the Sung Sot cave, called “The Surprise”), kayak in hidden lagoons, and greet the fishermen of the floating villages. At night, the anchor casts a veil of calm, and the stars become your companions.
History, culture, and… dragons
According to legend, dragons descended to protect the land, sculpting the islets by striking the sea. “Ha Long” actually means “the descending dragon.” Beyond the myth, the bay served as a strategic bastion against Mongol invasions. Today, fishing and pearl farming rhythm local life, particularly in Cua Van, a testament to a vibrant maritime culture.
When to go for the best weather
The calmest periods
From March to May and October to November, the weather is often ideal: mild to warm temperatures, calm sea, splendid light for photographers. In March, a poetic mist might greet you; in October, expect a few light showers.
Winter ambiance, cinematic mist
From December to February, it gets cooler, and mists are frequent. Visibility may sometimes diminish, but the ambiance gains in mystery—perfect if you enjoy muted settings and tranquility.
Heat, storms, and typhoon vigilance
From June to August, the heat rises, as does humidity; tropical downpours and storms are not uncommon, and the sea can get choppy. Between August and September, there is a risk of typhoons: keep a flexible schedule and monitor navigation notices, as some cruises may be canceled for safety.
Formalities, health, and insurance: the essentials
Depending on the duration and nature of your stay, a visa or e-visa may be mandatory before departing for Vietnam. Take time to check the latest entry requirements and refer to our article dedicated to visas before booking your flight.
On the health side, healthcare can be limited or expensive depending on the areas. Travel insurance is therefore highly recommended. Good deal: we’ve negotiated −5% on your insurance with Heymondo for worry-free travel. In case of unexpected events, you’ll be glad to have an ally.
What budget to plan for Halong Bay
The price mainly depends on the duration, the standard, and the included activities. In the daytime (6–8 hours), trips start from as low as 40–60 € per person (lunch, visit to a cave, sometimes kayaking or swimming). For a 2-day/1-night cruise — the most popular — count on 100–180 € depending on comfort, including private cabin, 3 to 4 meals, and several stops. The 3-day/2-night option (around 200–300 €) allows you to explore wilder areas at a relaxed pace.
Comfort tip: a cabin with a window or balcony changes everything at dawn when the mist drifts away. And if you’re looking for good deals towards Asia, check out the best travel offers for Asia to optimize your budget.
How to reach Halong Bay from Hanoi
Most travelers leave from Hanoi to cover the 160 km to the coast.
Buses and tourist shuttles: the simplest solution. Agencies and hotels in Hanoi offer direct transfers to Tuan Chau or the city of Ha Long. Expect to pay around 10 to 15 € per trip.
Train: picturesque but slow (about 6–7 hours), basic comfort. Avoid if your timing is tight.
Private car/taxi: perfect for families or groups seeking flexibility. Approximately 80–100 € to share.
Plane: the Van Don airport, around ~50 km away, offers a few connections. Add about an hour’s drive to the port.
Choosing your cruise without mistakes
In which area to navigate?
Halong Bay: the icon, the most accessible from Hanoi. Perfect for a first discovery but more crowded at peak hours.
Lan Ha Bay: to the south, same karst landscapes in a more peaceful atmosphere. Many departures are from Cat Ba.
Bai Tu Long Bay: to the northeast, the most preserved, fewer boats and a sense of space. The journeys here are a bit longer.
What duration to choose?
1 day: a condensed essential — sailing between islets, visiting a cave, kayaking or swimming break, returning at sunset.
2 days/1 night: the magic happens. Sunset and sunrise, breakfast on deck, anchoring in quieter areas.
3 days/2 nights: exploration deepens: floating villages, secluded lagoons, long moments of silence. Ideal for avoiding crowds.
Points to check before booking
Look closely at what is included: private cabin (for overnight stays), number of meals, activities (visits to caves, kayaking, cooking classes), transfers, possible French-speaking guide. Confirm the cancellation policy in case of unpredictable weather, and if the budget allows, opt for a cabin with a view or balcony.
What to see around Halong Bay?
Ninh Binh, the “dry Halong Bay”

Hanoi, the energy of the North
2–3 hours away, get lost in the Old Quarter, greet Hoan Kiem Lake in the early morning, and taste a bun cha and an egg coffee. If you love museums, head to the Ethnography or Women’s Museum.
Cat Ba National Park
If your cruise passes through Lan Ha, set aside a day for Cat Ba: hike to the park’s viewpoints, swim in coves, feast on seafood at sunset.
Hai Phong, the port stop
1.5 hours from the bay, wide avenues, colonial buildings, and convenient access to coastal islands. A tasty stop away from the crowd.
