Discover Halong Bay
Halong Bay isn't just a scenic spot; it's a living, breathing geological masterpiece where nearly 2,000 limestone karsts erupt from the emerald Gulf of Tonkin. This UNESCO World Heritage site feels like sailing through a mythical dragon's spine, where every turn reveals hidden lagoons, secret caves like Sung Sot (Surprise Cave), and the timeless rhythms of floating villages like Cua Van. The true magic unfolds aboard a traditional junk boat, where you can kayak into the heart of Thien Cung Cave's cathedral-like chambers or watch the sunset paint the karsts in fiery hues from the top deck.
Beyond the postcard views, Halong Bay offers a deep dive into Vietnam's coastal soul. Cat Ba Island provides a rugged, adventurous counterpoint with its national park and hiking trails, while Lan Ha Bay's quieter, southern waters reveal pristine coral beaches. This is a landscape that demands exploration—whether paddling through the three chambers of Luon Cave, visiting the pearl farms, or simply finding a quiet cove to absorb the profound silence of this ancient seascape.
Why Visit Halong Bay?
Sail a Legendary Seascape: Experience the iconic panorama from the deck of a traditional wooden junk boat, navigating through a maze of karst islands like Dau Go and Ga Choi (Fighting Cocks). Overnight cruises offer the unique chance to wake up surrounded by the bay's serene, misty beauty.
Paddle into Hidden Worlds: Kayak through archways and into secluded lagoons and caves inaccessible to larger boats. Glide through the tunnel of Luon Cave into a hidden lake or explore the dramatic, light-filled chambers of Dark & Bright Cave (Hang Sang Toi).
Explore Geological Wonders: Discover the bay's incredible cave systems. Walk through the vast, otherworldly formations of Sung Sot Cave (Surprise Cave), often called the most beautiful cave in Halong Bay, or visit the historical Trinh Nu Cave (Virgin Cave).
Connect with Floating Life: Witness the unique culture of the bay's fishing communities. Visit floating villages like Vung Vieng or Cua Van to see houses, schools, and fish farms bobbing on the water, offering a glimpse into a resilient way of life tied to the sea.
Adventure on Cat Ba Island: Use Halong Bay as a gateway to Vietnam's largest island archipelago. Cat Ba Island offers jungle trekking in Cat Ba National Park, rock climbing on its karsts, and quieter beaches, blending bay scenery with terrestrial adventure.
Capture Unforgettable Moments: The bay is a photographer's dream, with ever-changing light conditions. From the golden hour glow on the karsts at sunset to the ethereal morning mist, every moment presents a new, breathtaking composition.

Local Tips & Insider Knowledge
- •Book your cruise in advance, especially for overnight trips during peak season (Oct-Apr). Research operators carefully; price often reflects boat quality, safety, and itinerary.
- •For a less crowded experience, consider a cruise that explores Lan Ha Bay or Bai Tu Long Bay. These adjacent areas share the same stunning geology but have far fewer boats.
- •Pack a light rain jacket regardless of season. The weather on the bay can change quickly, and misty drizzle is common, adding to the atmosphere but potentially leaving you damp.
- •Bargain politely but firmly at the Halong Night Market and with non-fixed price vendors. Start at about 50-60% of the asking price and meet somewhere in the middle.
- •Bring cash (Vietnamese Dong) for small purchases on the bay, in villages, and at local markets. While hotels and cruise boats accept cards, smaller vendors and taxi drivers do not.
- •Be cautious when swimming. Always follow your guide's instructions, as currents can be strong in some areas, and jellyfish may be present, especially in warmer months.
- •Respect the environment. Do not litter overboard. Many operators now have eco-friendly policies; support them. Avoid single-use plastics where possible.
- •If prone to seasickness, choose a larger, more stable boat and bring medication. The bay waters are generally calm, but some passages can be choppy.
- •Visit Sung Sot Cave early in the morning or later in the afternoon to avoid the largest crowds from the big day-trip boats.
- •Learn a few basic Vietnamese phrases. A simple 'Xin chào' (hello) and 'Cảm ơn' (thank you) go a long way in showing respect to local guides and villagers.
Halong Bay Food Scene
Halong Bay's cuisine is a fresh, briny celebration of the sea, with daily catches from the Gulf of Tonkin taking center stage. Dining here is an integral part of the experience, from lavish seafood feasts on cruise boats to humble, flavorful street food in the harbor towns.
Must-Try Dishes
Cruise Boat Feast

Look for stalls with high turnover and locals eating there for the freshest and safest options.
Local Seafood Restaurant
- • Hong Ha Restaurant in Bai Chay
- • Oanh Dung Restaurant for crab
- • Family-run spots along the coast for whole steamed fish
Price is usually by weight. Confirm the price per kilogram before ordering to avoid surprises.

Halong Bay Hidden Gems
Ti Top Island (Hon Titop)
A small island with a crescent-shaped beach and a steep hiking trail to a panoramic viewpoint at the top.
While not entirely unknown, many day-trippers only stop briefly. Climbing the 400+ steps rewards you with one of the single best 360-degree views of the bay's karst formations, especially at sunrise or sunset.
Dau Be Island (Three Tunnels Lake)
An island featuring a unique inland lake accessed through three low, narrow tunnels only navigable by small boat or kayak.
It offers a thrilling, adventurous kayaking experience paddling through dark tunnels into a hidden, tranquil lake surrounded by vertical cliffs, feeling like a true explorer.

It provides fascinating context and history about the unique floating community's way of life, with artifacts and exhibits you won't find elsewhere on the bay, adding depth to your visit.
Ba Ham Lake (Three Internal Lakes)
A secluded area on Dau Be Island featuring three serene, ring-shaped lakes hidden inside a mountain, connected by tidal tunnels.

Ngoc Vung Island
A large, inhabited island in Bai Tu Long Bay with long, white sand beaches and a local village.
It offers a genuine slice of island life away from tourism. You can cycle through villages, visit ancient ruins, and have vast beaches virtually to yourself, a stark contrast to the busy core of Halong Bay.

Frequently Asked Questions about Halong Bay
How many days do I need in Halong Bay?

Is Halong Bay safe?
Yes, it is generally very safe. Choose reputable cruise operators with good safety records. Always follow your guide's instructions, especially when swimming, kayaking, or visiting caves. Be mindful of your belongings in crowded tourist areas on land.
Can I visit Halong Bay without a cruise?
It is very difficult to experience the core of the bay without a boat. However, you can enjoy views from the coast in Bai Chay, visit the Sun World park, or take a ferry to Cat Ba Island. To truly see the karsts and caves, some form of boat tour is essential.
What should I pack for an overnight cruise?
Pack light: swimwear, sunscreen, hat, sunglasses, comfortable shoes for cave visits, a light jacket (it can be cool on the water at night), insect repellent, cash for drinks/souvenirs, and a camera. Most boats provide towels and basic toiletries.
Are there ATMs and money exchange facilities?

Is the water in Halong Bay clean for swimming?
Water quality varies. In the open bay and designated swimming areas like Ti Top Beach, it is generally clean. Avoid swimming near floating villages or heavily trafficked harbor areas. Your cruise will stop at approved, cleaner spots.
Do I need a visa for Vietnam to visit Halong Bay?
Most foreign nationals require a visa to enter Vietnam. You must obtain this before arrival or arrange for an eVisa/Visa on Arrival approval letter. Check the latest requirements from the Vietnamese embassy well in advance of your trip.
What is the difference between Halong Bay, Lan Ha Bay, and Bai Tu Long Bay?
They are all part of the same stunning karst seascape. Halong Bay is the most famous and busiest. Lan Ha Bay (south) is quieter with more beaches and accessed via Cat Ba. Bai Tu Long Bay (northeast) is the least visited and most pristine, offering a more remote experience.
