Start with the basics: passport, visa documents, travel insurance (with cruise cover), smartphone, charger, headphones, toothbrush, sunglasses and camera. These are what you might call no-brainers.
However, cruising through Southeast Asia – and especially Vietnam and Cambodia – comes with its own distinctive suite of challenges and charms. Think tropical heat, sudden rain, temple visits and plenty of on-foot exploration.
This guide focuses on what’s specific to a Mekong River cruise, factoring in climate shifts, cultural norms and the realities of rural excursions. From sun hats to mozzie spray, here’s what to pack to make your Mekong journey smooth, stylish and stress-free.
What you’ll find onboard
Every cruise line is a little different, so it’s worth checking in advance. But most Mekong river ships – especially mid-range and up – will provide the essentials to keep you clean, comfy and camera-ready.
You can expect to find toiletries like shampoo, conditioner, body wash and body lotion in your cabin. Toothbrushes and razors are less common, so bring your own to be safe.
Bathrobes and towels are usually supplied, and many ships include slippers too (though occasionally you’ll need to request them). You’ll also very likely find a hairdryer tucked away in the bathroom cabinet.
One thing you won’t often find? Ironing facilities. Many ships offer a pressing service instead, which is worth knowing if you’re packing anything prone to creasing.
Clothing

Comfortable walking shoes and sandals
Exploring the Mekong means plenty of time on your feet, whether you’re wandering bustling markets, visiting rural villages or climbing temple steps. Put it this way – high heels are best left at home. The terrain is mostly flat but can be uneven, muddy and slippery, especially after rain. Choose sturdy, comfortable walking shoes with good grip for excursions, and bring sandals or slip-on shoes for easy on-and-off during temple visits or when boarding boats.
Flip-flops or pool slides are great for relaxing on deck or by the pool, and stylish flats or sandals can be worn for dinners or evening events onboard.
Casual, lightweight wear
The Mekong’s climate is hot and humid year-round, so you’ll definitely want lightweight, breathable clothing in natural fabrics like cotton, linen or silk. Loose-fitting shirts, shorts, trousers, skirts and dresses will keep you cool and comfortable. Light colours help reflect the sun and keep you feeling fresher.
Pack versatile pieces that can be mixed and matched, and consider wrinkle-resistant fabrics for convenience, as humidity can make creases a challenge. A couple of statement items (like a patterned shirt or bold earrings) add flair without overfilling your suitcase.
Modest attire for temples
Visits to temples and religious sites are a real highlight of most Mekong cruises, especially in Cambodia and Vietnam. Both men and women should cover their shoulders and knees; tank tops and short skirts or shorts are not permitted at all at holy sites like Angkor Wat. The smart move is to bring a lightweight scarf or shawl for extra coverage, which can also double as sun protection or a layer for cool evenings.
Evening wear
Onboard, the dress codes lean relaxed – think smart casual rather than fussy formal. A simple sundress, polo shirt or lightweight trousers and a blouse will work for most dinners. There’s no need for ball gowns or suits, but you may want to bring one slightly dressier outfit for a special dinner or event if you wish. A light cardigan or jacket is handy for cooler evenings or if you find yourself in an air-conditioned lounge.
Swimwear and Exercise Gear
Many Mekong cruise ships feature pools, hot tubs or sun decks, so bring a swimsuit for a refreshing dip or sunbathing. And if you plan to join morning tai chi, yoga or use the gym, pack comfortable, lightweight exercise clothes.
Essentials

Local currency
While major cities like Ho Chi Minh City and Phnom Penh accept card payments in hotels and larger shops, cash is still king in smaller towns, markets and for tipping. Vietnam uses the Vietnamese dong, and Cambodia primarily accepts the US dollar for most transactions (with small change often given in riel). Bring a supply of small US dollar notes and some dong if your cruise starts or ends in Vietnam. ATMs are available in larger towns, but may not always be reliable, or offer the best exchange rates. An anti-theft bag or money belt might be good for peace of mind in some quarters.
Medications
Pack all your usual prescription medications, along with a basic first aid kit including painkillers, plasters and any regular over-the-counter remedies you use. Motion sickness medication is generally not necessary, as river cruising is relatively smooth. However, it is wise to bring medication for stomach upsets and rehydration salts, as changes in diet and climate can sometimes cause minor issues.
Insect repellent
Mosquitoes are common along the Mekong, particularly at dawn and dusk and in rural areas. High-strength insect repellent is a must, ideally with DEET or a recommended alternative. Consider packing anti-itch cream and antihistamines as well, just to be on the safe side.
Electronics

Adaptors
Vietnam and Cambodia use a mix of plug types, most commonly type A, C and G. It’s good practice to bring a universal travel adaptor to ensure you can charge your devices in both countries. If you have several gadgets, pack more than one adaptor so you can charge multiple items at once.
Portable power bank
A portable power bank is invaluable for long days exploring markets, temples and rural villages. It will keep your phone, camera or other devices charged when you are away from the ship and may not have access to power points. This is especially useful for taking photos, using translation apps or navigating with maps, so you are never caught out with a flat battery.
Accessories and extras

Compact foldable umbrella or lightweight rain poncho
Sudden downpours are common on the Mekong, especially during the rainy season. A small foldable umbrella or a lightweight rain poncho is ideal for staying dry during shore excursions. Some ships provide umbrellas, but they are often large and cumbersome, so a compact version that fits easily in your day bag is a practical choice.
Reusable Water Bottle
Hydration is crucial in the hot, humid climate of Vietnam and Cambodia. Bring a reusable water bottle for excursions, as you will be walking a lot and bottled water is not always readily available in remote areas. Many cruise ships offer filtered water stations for refills, but bringing your own bottle ensures you always have water on hand and helps reduce plastic waste.
Day Bag or Crossbody Bag
A small backpack, tote or crossbody bag is essential for carrying your daily necessities such as water, sunscreen, insect repellent, camera and any souvenirs during excursions. Choose something comfortable to carry and secure enough for busy markets or crowded temples.
Stain Remover Pen
Spills can happen, whether it is a splash of pho broth or a drip of Vietnamese coffee. A stain remover pen is a handy addition to your bag for quick clean-ups, helping you stay presentable throughout your journey.
Bonus items
- Quick-dry travel towel for unexpected swims or freshening up on humid days.
- Travel laundry detergent for hand-washing essentials.
- Zip-lock bags for keeping electronics or documents dry during boat rides.
- Small torch or headlamp for early morning or evening excursions.
At the end of the day, packing for a Mekong River cruise is all about keeping things simple: travel light, bring only what you’ll truly use and leave a little space for unexpected treasures, be it a unique market find or a taste of local flavour to take home.
