For a cultural touch, visit floating villages or hike across deserted islands. Beyond nature, relish the vibrant local cuisine and Halong Bay travel with Vietnam Tour 247.
Overview about Halong Bay, Viet Nam
Located in northeastern Vietnam, Halong Bay is a breathtaking marine landscape comprising Halong City, Cam Pha Town, and the Van Don island district. This natural marvel covers approximately 1,553 $km^2$ and is home to nearly 2,000 limestone islands formed over 500 million years. Its unique karst geomorphology, shaped by a tropical wet climate, has created a world-renowned UNESCO World Heritage Site that serves as the heart of Halong Bay travel.
For those planning a visit, there is no shortage of things to do in Halong. The bay’s immense biodiversity, including tropical evergreen forests and over 60 faunal species, makes it a haven for eco-tourists. Whether you are exploring the 775 islands in the core zone or trekking through the lush greenery of Cat Ba Island, the scenery is a constant work of art.
Take a Leisurely Cruise
To fully appreciate the wonders of the region, an overnight or multi-day boat trip is widely considered the best Halong Bay travel option. While half-day junk boats and high-speed transfers are available, staying on the water for one or two nights allows you to be lulled to sleep by the currents—a peaceful way to enjoy Halong Bay at night far from the city lights.

Afterward, you can return to your yacht for sunset cocktails, perfectly transitioning into the magical evening atmosphere.
Dive and snorkel to investigate Coral Reefs
While many guides focus on the towering limestone karsts, Halong Bay travel also reveals a breathtaking universe beneath the surface. The bay is home to over 140 types of coral, with reefs surrounding islands like Cong Do covering up to 60% of the seabed. Protected by both geography and local laws, these vibrant ecosystems offer some of the most unique things to do in Halong.
Exploring this underwater world is a highlight for anyone deciding what to do in Halong Bay. Whether you are a novice or an expert, you can join a diving school to investigate hidden grottos or take a boat into deeper waters for snorkeling.

Submerging yourself in this marine landscape adds a profound layer to your journey, proving that the beauty of Halong is just as captivating below the waves as it is above them.
Explore Caves – Take a trip into the Mystic World
Exploring the bay’s legendary caverns is a cornerstone of Halong Bay travel. Outside of Cat Ba, the region is home to countless caves, each serving as a unique archaeological relic of the bay’s 500-million-year history. If you are deciding what to do in Halong Bay, visiting these three iconic caves is essential:

Thien Cung (Heaven Palace Cave): Renowned as the most beautiful, this cave is steeped in mythology. Soft, colored lights illuminate the “wedding venue” of the Dragon King, while natural skylights offer a dramatic, heavenly glow.
After exploring the depths, you can step out to breathtaking panoramic views, making these visits some of the most rewarding things to do in Halong.
Visit Lan Ha Bay or Bai Tu Long Bay
While Halong Bay is the most famous, savvy travelers know that Halong Bay travel also includes the neighboring Lan Ha Bay and Bai Tu Long Bay.

Tip for best time to visit Halong during weather
Choosing the right time to visit Halong Bay is essential for balancing perfect views with your favorite activities. Because Northern Vietnam has four distinct seasons, the Halong Bay weather will significantly change the “vibe” of your trip.
The “Golden Windows” (Best Overall)
For the most reliable conditions, aim for the shoulder seasons. These months offer clear skies and comfortable temperatures, perfect for all things to do in Halong.
-
Spring (March – April): Mild and blossoming. Expect temperatures between 18°C and 25°C. It’s the best time for kayaking and island hiking without the summer heat.
-
Autumn (October – November): Widely considered the “absolute best” time. The humidity drops, visibility is at its peak (ideal for photography and seaplane tours), and the sea is calm for cruising.
Important Halong Weather Tips
-
Storm Strategy (July – August): This is the peak typhoon season. While you’ll find great “low season” deals, there is a 20-30% chance of cruise cancellations. Always check the 3-day forecast and your operator’s refund policy.
-
The “Mystical” Winter: If you visit in January or February, the bay is often blanketed in a thick “Dragon’s Breath” fog. While not ideal for swimming, it creates a hauntingly beautiful atmosphere for photographers.
-
Swimming Note: If swimming is your priority, visit between May and September when water temperatures are a warm 28°C–29°C. In winter, the water drops to 19°C, which most find too chilly.
-
Domestic Peak: Avoid late April (Reunification Day) and the months of June/July if you want to avoid massive crowds of local travelers.

FAQs
1. Which port does my cruise depart from?
As of 2026, there are two main ports in Halong City. Most Halong Bay travel itineraries depart from Tuan Chau Marina, while many cruises heading to Bai Tu Long Bay or certain Halong Bay at night luxury vessels use the Sun World International Cruise Port (Bai Chay). Always double-check your booking voucher for the specific pier.
2. Is a day trip enough, or should I stay overnight?
While you can see the main highlights on a 6-hour day cruise, a 2-day, 1-night or 3-day, 2-night trip is highly recommended. Staying overnight allows you to reach quieter areas like Lan Ha Bay, enjoy sunrise Tai Chi, and experience the unique Halong nightlife on the water.
3. What is the best way to get from Hanoi to Halong Bay?
The fastest way is via the Hanoi-Haiphong Expressway. Most travelers book a “Luxury Limousine” shuttle, which takes about 2 to 2.5 hours. For a truly spectacular entrance, the 45-minute seaplane from Hanoi offers the best aerial views of the 2,000 islands.
4. Can I visit Halong Bay during the Lunar New Year (Tet)?
Yes! Halong Bay travel continues during Tet (expected in February 2026). While some shops on land may close, cruises operate as usual and often feature special festive menus and traditional decorations. It is a peaceful time with fewer domestic tourists.
5. Is the water clean enough for swimming?
Generally, yes. However, water quality is best in the “outer” regions. If swimming and snorkeling are your top things to do in Halong, look for itineraries that visit Lan Ha Bay or the Ba Trai Dao (Three Peaches) area, where the water is significantly clearer.
6. What should I pack for the Halong Bay weather?
-
Summer (May–Sept): Reef-safe sunscreen, swimwear, and light breathable clothing.

-
Year-round: Sturdy walking shoes for cave exploring and a waterproof bag for kayaking.

Yes, Halong Bay has a strict no single-use plastic policy. Avoid bringing plastic bags, disposable water bottles, or plastic straws. Most 2026 cruises provide refillable glass bottles or water stations to protect the marine ecosystem.
8. What if my cruise is canceled due to weather?
During the storm season (July–August), the Management Board may cancel all sailings for safety. Most reputable operators will offer a full refund or allow you to reschedule for the following day. Always have travel insurance that covers “trip interruption.”
