Two days is enough for Cat Ba if you accept that one of them is half-eaten by travel. This Cat Ba 2 day itinerary assumes you’re coming from Hanoi, staying one night in Cat Ba Town, and want swimming, a viewpoint and a bay trip rather than a checklist.
Budget roughly 1,600,000–2,600,000₫ (~$60–100) per person for two days, excluding upmarket hotels. Most of that is transport.
One thing to know before you plan anything: most Cat Ba itineraries online are years out of date. The prices in them stopped matching reality some time ago, and the island’s administrative name changed in 2025. Everything below is priced from 2026 sources, with the gaps marked rather than filled in.
Before you go
When to come
April to June is the usual recommendation: warmer water, less rain than midsummer, and the beaches aren’t yet at peak domestic-holiday capacity. July and August are hot, busy and squarely in the storm season for the northern coast. Winter is mild but grey, and swimming isn’t really on.
Weekends and Vietnamese public holidays are the real variable. Ferry queues and room prices both spike, and a self-drive trip that takes three hours midweek can take five.
Getting there from Hanoi
Roughly 150 km, and about 3 to 3.5 hours if nothing goes wrong. The bus-plus-boat operators are the sensible default for a two-day trip — they handle the sea crossing for you, which is where self-drivers lose their afternoon.
| Option | Price one way | Notes |
|---|---|---|
| Coach seat + boat | from 250,000–300,000₫ (~$10–11) | Old Quarter pickup, drop in Cat Ba Town |
| Limousine + boat | 360,000–420,000₫ (~$14–16) | 16–31 seats, more legroom |
| Self-drive + ferry | fuel, tolls and ferry | 4–5 hours on weekends and holidays |
Several operators run this route with their own boats and coaches; departures are frequent through the morning and early afternoon. Book the day before in high season.
Getting around the island
Rent a motorbike. Rates run about 150,000–200,000₫ (~$6–8) a day depending on whether it’s manual or automatic, more if you keep it overnight. The island road is fine, but it’s hilly and there are blind bends — this isn’t the place to ride one for the first time.
Taxis exist in and around Cat Ba Town. Grab coverage on the island is limited compared with the mainland.
The name change
Cat Ba is no longer in Cat Hai District. Since 1 July 2025 the whole island group has been part of Cat Hai Special Zone (đặc khu Cát Hải), Hai Phong — and Hai Phong itself absorbed Hai Duong province in the same restructure. Cat Ba Town is no longer a separate administrative unit either.
This matters for paperwork and for anything you’re reading online: every travel article still uses the old names.
Day 1: arrive, then Lan Ha Bay
Late morning — arrive
If you take an early departure you’ll be in Cat Ba Town around midday. Drop your bags at the hotel, eat, and don’t try to do a national park trek the same afternoon.
Afternoon — Ben Beo pier and Monkey Island
Ben Beo pier is a short ride from the town centre. From there, boats run out to Cat Dua Island, universally called Monkey Island, in 10 to 30 minutes depending on the boat.
The cost here is where old itineraries mislead people badly. Articles still quote around 80,000₫ (~$3) all in. In practice, in 2026:
- Island entry is reported at 80,000₫ (~$3) per person
- A private boat from Ben Beo runs anywhere from 400,000₫ to 1,500,000₫ (~$15–57) for the round trip, depending on boat size and season
- Some operators also charge a Lan Ha Bay fee of around 120,000₫ (~$4.60) per person
- Kayak hire is usually quoted per person per hour, not per kayak
Agree the total before you board, confirm the return leg is included, and confirm whether entry fees are in or out. Split across four or five people a private boat is reasonable; alone it is not.
The island itself: two small beaches, a short steep climb to a viewpoint, clear water, and macaques. The macaques are habituated and will take a bag or a bottle if you let them — carry nothing loose and don’t feed them, whatever you see other people doing. These are not the Cat Ba langurs, which live on the main island in and around the national park and number only 60 to 70 animals in total.
Evening — town and seafood
Back in town by late afternoon. The seafront is where the restaurants are: sam (horseshoe crab), tu hài (geoduck clam), bề bề (mantis shrimp), cá song (grouper) and squid are the local specialities.
Order by weight and confirm the price per kilo before anything goes on the grill — this is standard practice at seafood places across coastal Vietnam and not a Cat Ba quirk.
Day 2: beach, viewpoint, park
Early morning — Cat Co 3
The Cat Co beaches sit just east of town and are connected to it by cliff paths. Cat Co 3 is the quietest of the three. Going before 07:00 gets you an empty beach and cooler sand; by mid-morning in summer it will not be empty.
Mid-morning — Cannon Fort
Also called High Point 177, this is the hilltop battery above town, with two large guns, a tunnel system dug in the 1940s, and the best land-based view of Lan Ha Bay. It’s about 2 km from the centre; you can ride up and park.
Entry is 40,000₫ (~$1.50) per person according to recent 2026 visitor accounts. Older articles say 80,000₫, and there are small extra charges for the observatory and the telescopes. Sunset is the famous time here, but it doesn’t fit a two-day trip that ends with an afternoon boat. Take the morning view and accept the trade.
Late morning to early afternoon — Cat Ba National Park
About 14 km from town on the cross-island road, roughly 30 minutes by bike. The park covers over 16,000 hectares of primary forest and limestone.
This is also the part of the trip with the strongest claim on your attention, and most itineraries don’t mention why. Ha Long Bay and the Cat Ba Archipelago were inscribed together on the UNESCO World Heritage list on 16 September 2023, at the World Heritage Committee’s 45th session in Riyadh — the first World Heritage site in Vietnam to span two provinces. The archipelago contributes 358 of the site’s 1,133 limestone islands.
The listing counts 4,910 plant and animal species across the site, 198 of them on the IUCN Red List and 51 found nowhere else. The headline species is the Cat Ba langur: somewhere between 60 and 70 individuals survive, and they exist on this island and nowhere else on earth. You are very unlikely to see one. That’s rather the point.
Ticket pricing is tiered by route, and this is the other place old articles go wrong. Current listings show:
| Ticket | Adult | Child |
|---|---|---|
| Full park | 160,000₫ (~$6) | 80,000₫ (~$3) |
| Ngu Lam peak, kim giao forest and Trung Trang cave | 120,000₫ (~$4.60) | 60,000₫ (~$2.30) |
| Ninh Tiep – Tien Duc cave route | 80,000₫ (~$3) | 40,000₫ (~$1.50) |
| Phu Long mangrove – Thien Long cave route | 80,000₫ (~$3) | 40,000₫ (~$1.50) |
The flat 80,000₫ quoted in most itineraries appears to be one of the smaller route tickets, not park entry. Buy for the route you actually intend to walk.
For two days, the Ngu Lam peak ticket is the one that makes sense: a short sharp climb, a viewpoint over the forest, and you’re back at the gate inside two hours.
If you ever come back with more time, the trek to Ao Ech is the one worth planning around — a freshwater swamp forest sitting high in the limestone, growing a tree community that otherwise belongs to the Mekong Delta. It is one of the specific oddities the World Heritage listing singles out.
Afternoon — check out and leave
Back to town by early afternoon, check out, and take a mid-afternoon departure. Leave a buffer: this is the leg where a queue at the crossing turns a comfortable evening into a late one.
Where to stay
Cat Ba Town has the density — restaurants, boat piers and beaches all within a short ride — and for one night that convenience beats anything else.
- Budget guesthouses in town, roughly $10–20 a night for a double. Fine for one night; ask for a room away from the seafront if you want quiet.
- Mid-range hotels with a sea view, more, and worth it only if you’re staying longer than one night.
- Island resorts, including on Monkey Island itself. Beautiful setting, but you’re then committed to boat schedules for everything, which does not work on a two-day trip.
What to skip
The full national park ticket. Unless you’re doing a long trek, you’re paying double for access you won’t use.
A sunrise swim on day 2 if you were out late on day 1. Half the itineraries online schedule a 05:00 beach start after a seafood dinner. It reads well and nobody does it.
Trying to add Viet Hai village or a full Lan Ha Bay cruise. Both are good and neither fits. If a bay cruise is the thing you actually want, drop Monkey Island and Cannon Fort and give the bay a full day instead — it’s a better trip.

FAQ
Is two days enough for Cat Ba? For the town, one beach, one viewpoint and one bay trip, yes. For the national park treks or a proper Lan Ha Bay cruise, no — you want three.
Do I need to book the bus in advance? In high season and at weekends, yes, the day before at least. Midweek off-season you can usually turn up.
Can I do Cat Ba as a day trip from Hanoi? You can, but you’d spend six to seven hours travelling for three or four hours on the island. It isn’t worth it.
Is Cat Ba the same as Ha Long Bay? Not the same place, but since 2023 they share one UNESCO World Heritage listing. Cat Ba is the largest island of its own archipelago and the water around it is Lan Ha Bay — the same karst landscape, considerably quieter, which is much of the appeal.
Are the monkeys on Monkey Island safe? They’re macaques and they’re used to people. Keep your distance, don’t feed them, and don’t carry loose bags or bottles.
