“How to get to Cat Ba Island from Halong Bay?” is one of the biggest concerns for travelers who want to make the most of their Halong Bay trip. Cat Ba Island is renowned for its stunning beaches and tourist attractions, making it a fantastic destination in addition to Halong Bay. The good news is that getting between the two is now easier than ever, with several transport options depending on your time, budget, and travel style. Here are three recommended ways to travel from Halong Bay to Cat Ba Island.
Why Cat Ba Island Deserves a Spot on Your Halong Bay Itinerary
Most travelers arrive in Halong Bay and never look beyond the main cruise routes. That is a shame, because just 20 to 25 kilometers away sits Cat Ba Island, the largest island in the entire Halong Bay region and the gateway to Lan Ha Bay, one of Vietnam’s most breathtaking and under-visited destinations.
The limestone karsts are the same. The emerald waters are the same. But on this side, the boats are fewer, the beaches are quieter, and the experience feels genuinely authentic. Whether you have a single afternoon or a full week, making the crossing from Halong Bay to Cat Ba Island is one of the smartest decisions you can make on a northern Vietnam trip.
The distance is short, but knowing how to get there makes all the difference.
Getting from Halong Bay to Cat Ba Island: Your 3 Best Options
There are three main ways to make this crossing, each with its own rhythm and ideal traveler in mind. Here is an honest breakdown of all of them.
Option 1: Ferry to Cat Ba Island
For travelers who want to balance cost, comfort, and scenery, the ferry is the classic choice. And honestly, for good reason. Depending on where you are staying in Halong Bay, there are two departure points to choose from, each with its own practical advantages.
Departing from Tuan Chau Harbor → Gia Luan Ferry (Halong to Cat Ba)
| Category | Details |
|---|---|
| Route | Tuan Chau Harbor → Gia Luan Harbor (Cat Ba Island) |
| Distance from Bai Chay | 12–15 km |
| Transfer Cost (Taxi/Private Car) | ~150,000 – 200,000 VND |
| Ferry Duration | 45–50 minutes |
| Scenic Experience | Passes through some of the most beautiful parts of Halong Bay |
| High Season Schedule (May–Sep) | 07:30, 09:00, 11:30, 13:30, 15:00 |
| Return Schedule | 09:00, 11:30, 13:00, 15:00, 16:00 |
| Low Season Frequency | ~3 departures per day (each way) |
| Ticket Price | ~60,000 – 80,000 VND per person |
💡One important thing to know: the ferry only departs once at least 30 passengers are on board, so arriving with time to spare is always wise.
Best for: Budget travelers, those bringing a motorbike or vehicle, and anyone who wants the full scenic bay crossing experience.
Departing from Bai Chay Pier → Cat Ba Tourist Boat
| Category | Details |
|---|---|
| Route | Bai Chay Pier → Cat Ba Island |
| Best For | Travelers staying in Bai Chay who want to skip the transfer to Tuan Chau |
| Frequency | Less frequent than the Tuan Chau route |
| Ticket Purchase | Through tour operators (not at the pier counter) |
| Ticket Price | From ~250,000 VND/person + bay entry fee |
| Main Advantage | Direct departure near accommodation, no extra transfer needed |
| Trade-off | Higher cost and fewer departure options |
The scenery along both routes is genuinely spectacular. As the boat moves through the bay, you pass Ba Hang fishing village, Trong Mai Island, and a seemingly endless parade of limestone karsts rising from calm green water. It is one of those crossings that feels like part of the destination rather than just the journey to it.
Best for: Travelers based in Bai Chay who want a simpler, closer departure point without the extra taxi ride.
Expert Tip
Both piers fill up fast on weekends and Vietnamese public holidays. Whichever route you choose, aim to arrive at least 30 to 45 minutes before your intended departure. The smoothest approach is booking a private transfer package that handles everything from your hotel pickup to pier arrival and ticket, so there is nothing to figure out on the day.
Once at Gia Luan Harbor, a public bus or private taxi can take you into Cat Ba Town, with stops near Cat Ba National Park, Hospital Cave, and other key attractions along the way.
Option 2: High-Speed Boat for a Faster Crossing
When time is limited, and comfort matters, a high-speed boat is the smarter move.
How It Works
Departures are available from both Bai Chay and Tuan Chau, and the crossing takes only 20 to 30 minutes. The boats are smaller and more direct, which means less waiting around and more time actually enjoying Cat Ba Island.
Prices typically range from 250,000 to 350,000 VND per person. Capacity is limited to around 13 passengers per trip, so the experience feels more personal and less chaotic than the standard ferry.
Who Does This Suit Best
This option works particularly well for travelers on a tight itinerary, families with young children, or anyone who simply prefers to spend their time on the island rather than on the water. Booking in advance through a private tour operator is strongly recommended, as departures can sell out during peak season.
Option 3: Hydrofoil, the Fastest Way Across the Bay
For those who want to reach Cat Ba Island in the shortest time possible, the hydrofoil is in a league of its own.
How It Works
Operating from Tuan Chau Harbor, hydrofoils cover the crossing in as little as 10 to 15 minutes. Two companies currently run this route:
- Paradise Express: approx. 160,000 VND one way | (+84) 33 3842 368
- Kalong Hydrofoil: approx. 200,000 VND one way | (+84) 912 729 627
One Important Thing to Know
Neither company operates an English-language booking website, which makes reservations tricky for international visitors. Rather than navigating this alone, the most reliable approach is to book through a local travel expert who can handle the reservation on your behalf and confirm availability before your travel date. This is exactly the kind of service our team provides, so contact us, and we will sort it out for you.

The Most Seamless Option: A Cruise That Takes You There
If logistics are not your idea of a holiday, there is a fourth option that takes care of everything: a cruise that includes Cat Ba Island and Lan Ha Bay as part of the journey itself.
Why Lan Ha Bay Changes Everything
Lan Ha Bay wraps around the southern edge of Cat Ba Island, sharing the same dramatic limestone landscape as Halong Bay but with far fewer boats and a noticeably quieter atmosphere. Traveling by cruise through this area means you arrive already in the middle of one of Vietnam’s most stunning natural settings, with kayaking, cave visits, and beach stops built into the itinerary.
Recommended Cruises from Halong Junk Cruise
Not all cruises on this route are created equal. Some take you through the same crowded corners of Halong Bay that every other boat visits. The four below go further, into the quieter, more beautiful stretches of Lan Ha Bay, where the water is cleaner, the anchorages are peaceful, and Cat Ba Island is right on your doorstep.
Indochine Grand Cruise: Where French Colonial Elegance Meets Lan Ha Bay
Launched in 2025, the Indochine Grand is one of the newest and most refined vessels sailing this route. Thirty-two luxury cabins, every single one with a private balcony looking out over the limestone scenery. The design draws from the French Indochine era, which makes stepping aboard feel genuinely different from the standard cruise experience.
What sets it apart beyond the looks: a jacuzzi pool with panoramic bay views, a sky bar, a mini golf course at sea, and a Tonkin Restaurant serving fine dining set menus and buffet options. On the 3-day 2-night itinerary, you visit Dark and Bright Cave by bamboo sampan, explore Trung Trang Cave on Cat Ba Island, and wake up two mornings anchored in the silence of Lan Ha Bay. This is the one for travelers who want the best version of this experience.
Nostalgia Cruise: A Floating Piece of Vietnamese History
There is nothing else on the bay that looks like the Nostalgia Cruise. Built to resemble a miniature version of Hue’s Royal Palace, it is the only vessel on Lan Ha Bay that puts Vietnamese imperial heritage at the center of the experience rather than just the scenery around it.
Evenings on board include a proper Vietnamese tea ceremony, a fusion dinner in a dining room styled with French neoclassical and oriental touches, and happy hour at the bar as the sun drops behind the karsts. The itinerary covers Dark and Bright Cave by kayak, an overnight anchorage at Tra Bau in Lan Ha Bay, and a morning visit to Trung Trang Cave inside Cat Ba National Park. For travelers who want culture and luxury to sit side by side, this is the one to book.
Rita Cruise: 5-Star Innovation Built for Lan Ha Bay
Rita Cruise does things no other vessel on this route does. It has the first onboard swimming pool in Lan Ha Bay, a private soundproof karaoke lounge, and cabins where every single one comes with a private balcony and ocean view. The itineraries are deliberately routed away from the busier sections of the bay, which means quieter anchorages, less boat traffic, and more of the Lan Ha Bay experience that people come here for.
The 3-day 2-night program adds a bicycle trip through Viet Hai Village inside Cat Ba National Park, a stop at the Frog Pond area where parts of King Kong were filmed, and kayaking through Dark and Bright Cave. If you want modern luxury with an itinerary that actually goes somewhere different, Rita Cruise is the answer.
La Regina Grand Cruise: Colonial Style, Unhurried Pace
Twenty-seven suite cabins, each with a full-length window and private balcony, are styled after the colonial Indochina of the 1930s. La Regina Grand has a quiet confidence about it, the kind of cruise that does not need to shout because everything from the cabin design to the sundeck dinner service already speaks for itself.
The itinerary takes you to Light and Dark Cave by kayak, overnight in the calm waters of Lan Ha Bay, and into Trung Trang Cave on Cat Ba Island the following morning. The 3-day option adds Ba Trai Dao Beach and Viet Hai Village, giving you a genuine slice of island life alongside the bay scenery. Warm service, unhurried pace, beautiful surroundings.

When Is the Best Time to Visit Cat Ba Island?
Cat Ba rewards you differently depending on when you show up. The island is technically open year-round, but the season you choose shapes everything from the light on the water to how many other people are sharing it with you.
Spring and Early Summer: Clear Skies, Calm Water
April through June is when Cat Ba is at its most visually striking. The air is warm, the skies are reliably clear, and the emerald water of Lan Ha Bay looks exactly like the photographs you have been saving. Crowds are present but manageable, and the conditions for kayaking, hiking, and boat tours are about as good as they get. If you are planning to spend serious time outdoors, this is your window.
Autumn: The Insider’s Pick
September through November is when the island feels most like itself. The summer rush has cleared, temperatures soften, the light turns golden in the late afternoon, and the bay takes on a serenity that is genuinely hard to describe until you have seen it. This is the season that regular visitors tend to come back for, and the one we recommend most often to travelers who want quality over convenience.
Summer: Go, but Go Prepared
From May to July, domestic tourism peaks and Cat Ba becomes considerably livelier, particularly on weekends and public holidays. The beaches fill up, the restaurants get noisy, and the ferry queues grow long. None of this makes it a bad time to visit, but it does make planning more important. Traveling on weekdays, booking accommodation well in advance, and having a private itinerary arranged ahead of time make an enormous difference to the experience you actually have.
What to Do Once You Arrive on Cat Ba Island
Most travelers allocate half a day to Cat Ba and end up staying three. Simply put, the island has a way of making itself indispensable. Here is what is genuinely worth your time, from the well-known to the ones most people miss entirely.
Beaches of Cat Co
Cat Ba has three Cat Co beaches, each with its own character. The first Cat Co beach is the liveliest, with a wide stretch of sand and resort facilities close by. Cat Co 2, on the other hand, is quieter with softer sand and a more relaxed crowd. Cat Co 3 sits closest to town and links to Cat Co 1 via a scenic coastal path that is worth walking just for the views. One local rule to remember: get out of the water before 18:30, when the tide shifts and conditions turn rougher without much warning.
Hospital Cave: History Inside a Mountain
Most visitors walk straight past the entrance. As a result, you often have this extraordinary place almost to yourself. During the Vietnam War, this three-level cave served as a fully functioning underground hospital, complete with operating rooms, a cinema, and sleeping quarters for hundreds of soldiers. Walking through it today is genuinely moving. Furthermore, entrance costs just a few dollars, and the cave sits only a ten-minute ride from Cat Ba Town. A private guided visit adds context that transforms it from a curiosity into something you carry home with you.
Cat Ba National Park: Where the Island Gets Wild
Covering the majority of the island, this UNESCO Man and Biosphere Reserve is home to dense tropical forest, over 70 bird species, and the critically endangered Cat Ba langur. Fewer than 80 of these primates remain in the wild. Trekking routes range from a 90-minute climb up Ngu Lam Peak to the full-day 9-kilometer trail to Viet Hai Village. Going with a private guide is the difference between a walk in the forest and an experience with genuine depth. A good guide knows the langur sightings, the bird calls, and the stories behind the landscape.
Viet Hai Village: Real Life, Unscripted
Tucked inside Cat Ba National Park, Viet Hai is reachable only by boat or on foot. Fishermen and farmers live here at a genuinely slow pace, surrounded by stilt houses and rice fields framed by limestone mountains. Arriving by private boat tour and spending a few hours cycling through the village, rather than rushing through on a group excursion, gives you a kind of access that most travelers never experience. Locals are warm and welcoming, and the quietness of the place stays with you long after you leave.
Kayaking in Lan Ha Bay: The One Everyone Talks About
Paddling through narrow limestone passages, slipping into hidden lagoons, and pulling up to empty beaches: kayaking in Lan Ha Bay lives up to every story you have heard about it. The bay holds over 300 karst islands. Even so, the less-visited areas feel genuinely remote. Most day tours from Cat Ba Island include kayaking alongside stops at Cai Beo floating village and caves like Light Cave and Dark Cave. For something more immersive, a private full-day tour gives you far more control over where you go and how long you stay.
Bioluminescence Kayaking: The After-Dark Secret
This is the one most blogs do not mention. After dark, certain areas of Lan Ha Bay glow with bioluminescent plankton, turning the water around your paddle electric blue with every stroke. Tours run in small groups from Cat Ba Town. However, they are best booked through a trusted local operator who knows which areas are active on any given night. Most people describe it as the most memorable thing they did on the entire trip.
Monkey Island
Just a ten-minute boat ride from town, Monkey Island has two clean beaches and a resident colony of macaques who have long since figured out that tourists carry snacks. It is fun, photogenic, and easy to combine with a half-day on the water. That said, keep food out of sight and maintain a respectful distance. The monkeys are wild and can be unpredictable when food appears.
Where to Stay on Cat Ba Island
The accommodation scene has grown considerably in recent years. Options now range from no-frills guesthouses to boutique hotels perched above the bay. Most properties sit along the coastline, so you typically get either direct beach access or water views, sometimes both.
Before you book, a few things are worth knowing. Weekend rates run 20 to 50 percent higher than weekday prices, and public holidays push them even further. In addition, the best rooms at popular properties book out weeks ahead during peak season. Staying slightly outside Cat Ba Town also tends to mean more peace and better value, particularly as construction along parts of the main seafront continues through 2026.
Our team at Halong Junk Cruise arranges private accommodation bookings across every budget range, including properties that do not surface on standard platforms and guesthouses that locals actually recommend. Reach us directly at [email protected] or visit our website to start the conversation.
