What to Pack for a Halong Bay Cruise: The Complete Checklist

Swimwear, a quick-dry towel (though most boats provide one), high-SPF reef-safe sunscreen, sunglasses and a sun hat are non-negotiable for the deck. Pack comfortable shoes or sandals with grip — cave steps can be damp and slippery — plus light, breathable clothing for the daytime heat.

Bring any personal medication, a basic first-aid item or two, insect repellent for shore excursions, and a power bank to keep your camera and phone charged for sunrise. A small dry-bag is invaluable for kayaking, keeping your phone and valuables safe from splashes.

In summer (May–August), prioritise light, loose clothing and a thin rain shell for sudden afternoon showers. In winter and early spring (December–April), add a warm layer, a light jacket and long trousers for the misty mornings and breezy evenings on the open sun deck — the water makes it feel cooler than the city.

Spring travellers should expect damp, humid air, so quick-dry fabrics beat heavy cotton. Whatever the month, evenings on deck are cooler than the day, so one warm layer is worth packing even in the height of summer.

A few non-essentials punch above their weight: a refillable water bottle (many cruises offer refill stations to cut plastic), a book or e-reader for slow afternoons, a light scarf or sarong that doubles as sun cover and a wrap for dinner, and motion-sickness tablets if you are prone to seasickness — the bay is calm, but the open transfer between harbour and anchorage can have a gentle swell.

A little cash in small notes is handy for tips, drinks and souvenirs at floating villages or pearl farms, as card facilities on board can be limited.

You do not need formal clothes — even on luxury vessels, dinner dress is smart-casual at most. Skip the hairdryer (cabins usually have one), heavy guidebooks, and bulky toiletries; travel sizes are plenty for one or two nights.

If you are continuing your travels after the cruise, ask your Hanoi hotel to store your main suitcase. Almost all do this free of charge, leaving you to travel light to the bay and collect everything on your return.

Confirm your transfer pick-up time and point, keep your booking confirmation and a photo ID accessible, and check the forecast the day before so you can layer accordingly. With a small, well-chosen bag you will be free to focus on what matters — the karsts, the kayaking and the quiet of the bay at dawn.
