Halong Bay Packing List 2026, What to Bring

Quick summary: A Halong Bay packing list starts with six items: a reusable water bottle, shoes with grip for the caves, a light layer for the deck, a waterproof phone pouch, a passport and some Vietnamese dong in cash. A day trip needs only a daypack, while a 2 days 1 night Halong Bay overnight cruise needs one small bag per person.

Many travelers pack for a sunny beach, then arrive in Halong Bay in January to a gray sky and wind on the water. This list is based on what a boat trip in the bay actually involves: a road transfer, time on deck, damp cave steps, kayaking and a swim stop.

The short version

• Reusable water bottle. Single-use plastic is banned on the bay.
• Two pairs of shoes. One pair with grip for damp cave floors, and one pair that slips on and off for the deck.
• A light layer in every season. The deck is cooler and windier than the shore.
• Waterproof phone pouch. Kayaking gets wet, and the camera is still needed.
• Passport or a clear photo of it. Staff check documents before boarding.
• Vietnamese dong in cash. Small bars, small boat rides and tips often do not take cards.

What to bring also depends on the trip:

• The Halong Bay Day Tour from Hanoi (from $34) needs a daypack only.
• The Halong Bay to Lan Ha Bay Day Tour (from $60) needs a daypack and swimwear.
• An overnight cruise such as the La Casta Regal Cruise (from $155) needs a small overnight bag.

What to pack for Halong Bay

Pack for a boat, not a beach. The essentials are one warm layer, one waterproof layer, shoes with grip, swimwear, a reusable bottle and documents. Space on board is limited, so leaving things behind matters as much as packing.

Documents and money

Bring the passport itself if possible. Some piers accept a photo on a phone, but others ask for the original. Carry small Vietnamese dong notes for drinks, the small boat ride to the beach and tips.

Clothing for the deck and the caves

Layers work better than full outfits. A T-shirt, a long-sleeved shirt and a light windproof jacket cover most conditions on the water. Quick-dry fabric is better than cotton, which stays damp for hours after kayaking. For an overnight cruise, add one smart-casual outfit for dinner.

Footwear

Cave floors stay damp all year, and the stone steps at Sung Sot Cave are worn smooth. Sneakers with a good sole are the right choice. Flip-flops are useful as a second pair for the deck, the beach and the cabin. Hiking boots are only worth packing for a trekking day in Cat Ba National Park.

Water gear

A dry bag or zip pouch for the phone is the most useful item for the water. Wear swimwear under clothes on swim days, because changing space on small boats is limited and swim stops are short.

Health and comfort

Take motion sickness tablets before boarding if needed. The bay is sheltered, but the road from Hanoi can cause nausea. Use sunscreen even in winter, because the light reflects off the water and sundecks have little shade. A power bank helps, since cabin sockets are limited.

What to wear in Halong Bay by season

Halong Bay has four seasons, and the clothing changes with each one. Month by month weather, sea temperature and rainfall are covered in the best time to visit Halong Bay.

• March to May. T-shirts and one long-sleeved shirt, plus a light windproof jacket. Add a rain shell for showers in May.
• June to September. The lightest quick-dry clothes and a packable rain shell. Long trousers are still useful in the caves. This is the main swimming season.
• October to November. T-shirts, one long-sleeved shirt and a light jacket for cool evenings.
• December to February. A warm base layer, a proper jacket and warm socks for the deck at night. Most guests skip swimming.

What not to pack for a Halong Bay cruise

• Single-use plastic bottles. They are banned on the bay.
• Hard suitcases over 24 inches. They do not fit under cruise beds and are awkward on small boats.
• Drones. Drone flights in the heritage area are restricted, so check with the cruise before bringing one.
• Valuable jewelry. Kayaks can tip and sand gets everywhere.
• Formal clothes and heavy books. Evenings on board are short and casual.
• Large bottles of toiletries. Overnight boats supply the basics.

How much luggage can you bring on a Halong Bay cruise?

Cruises rarely publish a weight limit. Cabin space is the real limit, and one carry-on size bag per person fits comfortably. Day trips have no cabin, so a daypack is enough.

Large suitcases can stay in Hanoi, where many hotels store bags for guests returning after the cruise. Beka Travel offices in Hanoi and Cat Ba can also keep large bags for guests. If you continue to Cat Ba or Ninh Binh after the cruise, mention it at booking so the vehicle has room for the luggage.

Do you need a plug adapter in Vietnam?

Vietnam uses 220V at 50Hz, and sockets take both flat and round two-pin plugs. Chargers from Europe and most of Asia work without an adapter, while travelers from the UK need one. Travelers from North America and Japan should check that each device supports 220V. Phone and laptop chargers usually do, but hair tools often do not. Cabins have few sockets, so a multi-plug or power bank helps.

How does the plastic ban change what you pack?

Single-use plastic products have been banned on Ha Long Bay since 1 September 2019, as reported by vietnamplus.vn. The rule covers plastic bottles, bags and straws on boats and at the sites.

The ban is enforced. A tour boat was suspended for letting guests use plastic bottles on the bay, according to voh.com.vn. A refillable bottle avoids the problem, and overnight boats usually have water refill points.

What do you need for the water activities?

Each water activity needs one key item: a dry pouch for kayaking, a quick-dry towel for swimming and shoes that can get wet for the small boat ride. Kayaks and life jackets are provided on tours that include kayaking, so no personal equipment is needed. Reef-safe sunscreen is a good addition.

Travelers who mainly want to swim may prefer the quieter bay next door. The differences are explained in Halong Bay vs Lan Ha Bay.

Frequently asked questions

Is there a luggage weight limit on Halong Bay cruises?

Most cruises do not publish a weight limit. Cabin space is the practical limit, so one carry-on size bag per person is sensible. Day tours allow a daypack only. Confirm large sports equipment at booking.

Where can you leave a large suitcase during a Halong Bay cruise?

Ask your Hanoi hotel at check-out, since many store bags for guests who return after the cruise. Keep the luggage ticket. Beka Travel offices in Hanoi and Cat Ba can also store large bags for guests.

Is laundry available on Halong Bay cruises?

Assume not. Most overnight cruises do not offer laundry, so pack enough clothes for the trip. A quick-dry shirt rinsed in the cabin sink dries overnight in most months, but not in the humid summer.

What swimwear should you bring to Halong Bay?

Bring swimwear that can be worn under clothes all day. Changing space on day boats is small and swim stops are short. A rash vest helps from May to September, when the sun is strongest.

Do you need hiking shoes for the Halong Bay caves?

No. Sneakers with a good sole are enough for the caves. The paths are paved and lit, but the stone stays damp and the steps are worn smooth. Flip-flops are not suitable for the caves.

Can you buy forgotten items in Halong Bay?

Yes, basics like sunscreen, flip-flops, hats and rain ponchos are sold near Tuan Chau and Bai Chay at tourist prices. Buy medicine and brand-specific items in Hanoi before the trip. Shops on board sell only drinks and snacks.
