Pack for Cat Ba around three facts: half your days start on a boat, the trails are limestone and root, and Viet Hai village has no ATM, no pharmacy and no shops — so a dry bag, grippy shoes and enough cash matter more than anything else in the bag. We watch people unpack every week, and the same items are missing every time. This is not a generic tropical packing list — it is what actually matters on an island where the weather changes fast, half the days involve a boat, and the nearest shop may be an hour away by water.
| Never forget | Dry bag, cash, mosquito repellent, head torch, any medication you rely on |
| Shoes | Trainers or light hikers with grip for the park; sandals with a heel strap for boats and kayaks |
| May–September | Quick-dry clothes, a long-sleeve sun shirt, two swimsuits, a hat with a cord, a light rain jacket |
| December–March | A real warm layer and a windproof for boat days; rooms are not heated; closed shoes for muddy trails |
| Cash | ATMs in Cat Ba town only; many local restaurants and boats cannot take international cards; bay ticket 120,000 VND and cart 50,000 VND are paid in cash |
| Leave at home | Heavy boots, formal clothes, a hairdryer, bulk toiletries, a drone you have not checked the rules for |
What do travellers most often forget to pack for Cat Ba?
- A dry bag. Boat days and kayaking both end with spray. A 10–20 litre dry bag protects a phone, passport and camera and costs almost nothing.
- Cash. There is no ATM in Viet Hai village and card acceptance is patchy outside Cat Ba town. Draw money before you get on the boat.
- Mosquito repellent. Dusk near the rice fields is when you need it, and village shops do not stock it.
- A head torch. Village paths are unlit and the valley gets properly dark.
- Any medication you actually rely on. The nearest pharmacy is in town.
What clothes should you pack for Cat Ba by season?
May to September — hot and humid
- Light, loose, quick-dry clothing — cotton stays wet all day
- A long-sleeve sun shirt: cooler than bare arms on a boat and better than reapplying sunscreen
- Swimwear × 2, so one is always dry
- Hat with a chin cord — the bay is windy
- A light rain jacket. Afternoon downpours are heavy and brief
October to November — the best months
- Everything above, plus one light layer for evenings and boat mornings
December to March — cool and damp
- A proper warm layer. A damp 17°C feels colder than the number suggests, and rooms here are not heated
- A windproof layer for boat days — this is the one people underestimate
- Closed shoes; trails stay muddy for days
What shoes should you bring to Cat Ba Island?
- Trainers or light hiking shoes with grip. Cat Ba National Park trails are limestone rock and tree roots, slippery when wet, and genuinely steep in places. People attempt them in flip-flops every week and some of them get hurt.
- Sandals with a heel strap for boats and kayaks. Flip-flops come off in water.
- That is it. Two pairs.
What should you pack for boat and kayak days?
- Dry bag (again — it is the single most useful item)
- Sunglasses with a strap
- Reef-safe sunscreen, high factor
- A microfibre towel
- More water than you plan to drink
- Motion sickness tablets if you are prone — small boats in choppy water are a different experience from a ferry
On the full-day Lan Ha Bay boat tour you swim, kayak and eat on the water between 09:00 and 15:30, so the dry bag, sun shirt and strap sandals earn their place on day one; the sunset and night kayaking adds a head torch and a warm layer for the paddle back after dark. If you trek across the park to us, we send your luggage ahead by boat for a fixed 350,000 VND so you walk with a day pack. Rates for the tours move with the season and group size — ask us for the current one.
What should you leave at home when visiting Cat Ba?
- Heavy hiking boots. Overkill for these distances and miserable in humidity.
- Formal clothes. There is nowhere on this island that requires them.
- A hairdryer. Nothing dries in summer anyway, and rooms have limited sockets.
- Large amounts of toiletries. Cat Ba town has everything.
- A drone, unless you have checked. Much of the bay and the national park is protected and flight rules apply; ask locally before you launch.
What documents and money do you need for Cat Ba?
- Passport — needed for hotel check-in everywhere in Vietnam
- Travel insurance covering kayaking and trekking; medical evacuation from an island is slow and expensive
- An eSIM bought before arrival — coverage is good across most of the island
- A photo of your passport stored offline
- Cash, and enough of it. Many local restaurants, small shops and boat operators have no card machine at all, and those that do often cannot take international cards. Withdraw what you need in Cat Ba town before you travel on to the village
One last thing
Do not worry about packing perfectly. Cat Ba town has shops for almost anything you forget, and the walk from the pier into the village is short and flat, so travel light and enjoy the trip. If you are not sure whether to bring something, message us before you pack and we will tell you honestly whether you will actually use it.
Frequently asked questions about packing for Cat Ba
Answered by the Lan family in Viet Hai — the people who run the boats, cook the dinner and pick you up at the pier.
What is the one thing people forget to pack for Cat Ba?
A dry bag. Boat days, the speedboat to the village and kayaking all end with spray, and a 10–20 litre dry bag keeps a phone, passport and camera safe for almost no money. Cash is the close second: there is no ATM in Viet Hai and many local places cannot take international cards.
What shoes do I need for Cat Ba Island?
Two pairs. Trainers or light hiking shoes with grip for the national park, where the trails are limestone rock and tree root and slippery when wet, and sandals with a heel strap for boats and kayaks, because flip-flops come off in water. Heavy boots are overkill for these distances and miserable in the humidity.
How much cash should I bring to Cat Ba?
Enough for the fixed fees — Lan Ha Bay ticket 120,000 VND adult, electric cart 50,000 VND, park routes 80,000–160,000 VND — plus meals, drinks and small purchases in town. Withdraw in Cat Ba town before crossing the bay. At the homestay you can pay the room by card with a 3% bank fee, so cash can go to the places that only take cash.
What should I pack for Cat Ba in winter?
A proper warm layer and a windproof one: from December to March a damp 17°C feels colder than it sounds, rooms are not heated, and the boat is windy. Closed shoes for muddy trails, and still the sun shirt and hat — winter days can be bright. Swimwear is optional; most people do not swim.
Can I buy things I forget on the island?
In Cat Ba town, yes — toiletries, sunscreen, snacks, basic clothing, a pharmacy. In Viet Hai village, no: there are no shops at all, and the nearest is 30 minutes away by speedboat. Buy anything you need in town before the boat, especially repellent, medication and cash.
Do I need travel insurance for Cat Ba?
Yes, and check it covers kayaking and trekking. Cat Ba town has a small hospital; anything serious goes to Hai Phong by boat, which is slow and expensive without cover. Carry a photo of your passport offline and keep the original with you — Vietnamese hotels and homestays must see it at check-in.
