Cat Ba is the independent traveler's answer to a packaged Ha Long cruise. This covers the transport chain from Hanoi or Hai Phong, how to pick a Lan Ha Bay boat, what three days actually costs, and the mistakes that cost people their trip.
Cat Ba is administratively part of Hai Phong, in what was Cat Hai district and is now run as the Cat Hai special zone. For most English-speaking visitors it is the do-it-yourself answer to a Ha Long Bay cruise: the same limestone seascape in the adjoining Lan Ha Bay, but with beaches you can swim to, a national park behind you, and no fixed cruise schedule. Independent travel here is straightforward, but three things reliably catch first-timers out: the route onto the island, the choice of boat tour, and not planning for rough seas.
Getting there from Hanoi
International flights land at Noi Bai airport, about 35km (22 miles) north of central Hanoi, with a car into the Old Quarter taking 45 minutes to an hour. From Hanoi, the easiest option to Cat Ba is a direct limousine bus, where the operator handles the sea crossing as part of the fare. If you drive yourself, the usual route runs down the expressway to Hai Phong, over the sea bridge to Cat Hai island, then across by ferry or cable car. Total travel time is roughly four and a half to five and a half hours.
- Direct limousine bus from Hanoi: simplest, roughly 250,000-350,000d per leg (about US$10-14), estimated
- Self-drive car: flexible, but expect ferry queues in peak season and very tight parking in town
- Fast boat from central Hai Phong: quick, and sensible if you are already in the city
- From the Ha Long side: a ferry crosses to the north of the island, with sailings that shift with the weather
Arriving from elsewhere in Vietnam
If you are coming up from Ho Chi Minh City or Da Nang, Hai Phong has its own airport at Cat Bi with domestic connections, which saves you the drive out from Hanoi entirely. From the airport you take a taxi or a Grab, the ride-hailing app most people in Vietnam use in place of hailing a cab, into the city and then onward to the island. Coming from Ha Long, the ferry crossing to the north end of Cat Ba is short but weather-dependent, so ask about the day's sailings before you commit to it.
Getting around the island
The town is small enough to walk almost everywhere within it. To reach the national park or ride the road across the island, renting a motorbike is the obvious move, at roughly 150,000-250,000d a day (about US$6-10) excluding fuel, as an estimate. The roads climb and twist with plenty of blind corners, so if you are not a confident rider, take an electric buggy or a taxi instead. Check the brakes and photograph the bike before you ride off.
Choosing a Lan Ha Bay boat tour
This is the decision worth spending twenty minutes on. There are three broad types: a half-day loop around the fishing village and nearby beaches, a full-day trip deeper into the bay with kayaking and swimming, and an overnight on board. Do not shop on price alone. Ask which stops the boat makes, whether kayaks are included, how lunch works and what time it returns to the pier. Two boats a few hundred thousand dong apart can run completely different routes.
- Half day: good for tight schedules or families with young children
- Full day: the default choice, roughly 400,000-700,000d per person (about US$16-28), estimated
- Overnight on the bay: much more expensive, but you get dawn and dusk without day boats
- Always ask whether the bay entry fee is included in the quoted price
Where to stay and what to eat, briefly
Most people stay along the harborfront strip in Cat Ba town, because the pier, the market and the Cat Co beaches are all a short walk away. Quieter alternatives are the small resorts in the southern coves or a homestay in Viet Hai village, which in Vietnam means a room in a family home with meals usually included. Food is seafood by default, and the safe way to order is to ask the price per kilo, choose your own animal, watch it weighed, then decide how it is cooked.
What three days costs
- Return transport Hanoi to Cat Ba: 500,000-700,000d (about US$20-28)
- Mid-range hotel room in summer: 700,000-1,500,000d a night (about US$28-60), less split between two
- Full-day bay tour: 400,000-700,000d per person (about US$16-28)
- Food: 300,000-500,000d per person per day (about US$12-20) if you eat seafood daily
- Motorbike rental, entry tickets and incidentals: 300,000-500,000d (about US$12-20)
- All in, roughly 2,000,000-3,500,000d per person (about US$80-140) for three days, as an estimate
The thing most likely to ruin a Cat Ba trip is not cost, it is weather. Two days before you travel, check the wind forecast and the boat situation. If the sea is rough the bay tours stop and you have come all this way to watch rain from a hotel window. A refundable room is exactly what you booked it for.
Visas, money and timing
Vietnam runs an online e-visa that covers most nationalities, applied for before you fly; check the official government portal for current requirements rather than relying on a blog, since the details change. Money is the dong, hovering somewhere near 25,000d to the US dollar, and outside hotels and larger restaurants cash is still king on the island. Bring notes for small boats, parking and market stalls. On timing, storms are most likely between about July and September, so book cancellable accommodation in those months.
What to bring
- Cash in dong for rowing boats, parking, market stalls and small restaurants
- Sunscreen, a wide-brimmed hat and a thin long-sleeved layer for the day on the boat
- Shoes with grip if you plan to climb Ngu Lam peak or walk in the national park
- A dry bag for your phone while kayaking
- Motion sickness tablets if you are prone to it, since the crossing can be choppy
- A light jacket for evenings on the water, even in midsummer
