Packing Philosophy
Bangkok rewards light packers. The city is hot, humid, and full of cheap shopping — so bring less than you think you need. A carry-on-sized bag (40-45 litres) is plenty for a week-long trip.
- Pack for 3-4 days of clothing and do laundry at your hotel or a local laundry shop (40-60 THB per kilo, returned same day).
- Prioritise quick-dry, breathable fabrics over cotton — you'll sweat through cotton in an hour.
- Leave room in your bag for souvenirs. Bangkok's markets are hard to resist.
Laundry services are everywhere in Bangkok. Most guesthouses and hotels offer same-day laundry for 40-60 THB per kilo, making it easy to pack light.
Clothing Essentials
Bangkok's heat and humidity demand lightweight, breathable clothing. Here's what to bring:
- Tops: 3-4 lightweight T-shirts or tank tops in moisture-wicking fabric. Linen blend shirts work well for nicer restaurants.
- Bottoms: 2 pairs of lightweight trousers or long shorts. At least one pair of long trousers for temples. Convertible zip-off trousers are practical.
- Dresses/skirts: Maxi dresses and knee-length skirts are ideal — cool in the heat and temple-appropriate.
- Underwear: 4-5 pairs of moisture-wicking underwear. Avoid cotton in tropical humidity.
- Sleepwear: Light shorts and a T-shirt. Most accommodation has strong air conditioning at night.
- Swimwear: One swimsuit if your hotel has a pool, or if you're planning a day trip.
- Light layer: A thin cardigan or hoodie for heavily air-conditioned malls, cinemas, and the BTS. The temperature difference between outdoors (35 C) and indoors (20 C) is extreme.
Dark colours show sweat less but absorb more heat. Light-coloured clothing in breathable fabrics is the best compromise for Bangkok's climate.
Temple-Appropriate Outfits
Bangkok's major temples enforce dress codes strictly. The Grand Palace is the most rigid, but Wat Pho and Wat Arun also require modest clothing.
| Body Area | Required | Not Allowed |
|---|---|---|
| Shoulders | Covered (sleeves or shawl) | Tank tops, spaghetti straps, strapless |
| Knees | Covered (below the knee) | Shorts above the knee, miniskirts |
| Feet | Shoes removed inside temples | No restrictions on footwear outside |
| General | Neat, non-transparent clothing | See-through fabrics, ripped jeans, tight leggings |
- Carry a lightweight scarf or sarong in your day bag. It doubles as a shoulder cover, a picnic blanket, and a sun shield.
- Elephant-print harem pants from Khaosan Road (100-150 THB) are a Bangkok classic, are temple-approved, and make comfortable travel trousers.
- Some temples sell or lend cover-ups, but don't count on it — especially at smaller temples outside the main tourist circuit.
The Grand Palace turns away visitors who don't meet the dress code. Sarong rentals are available near the entrance (200 THB deposit), but the queue can add 20-30 minutes to your visit.
Rain and Weather Gear
Whether you visit in the rainy season or not, be prepared for sudden downpours. Bangkok's weather is unpredictable, especially from May to November.
- Compact umbrella: A small folding umbrella fits in any day bag and doubles as sun shade. Available at 7-Eleven for 100-150 THB if you forget yours.
- Packable rain jacket: A lightweight, breathable rain shell is better than a poncho for walking in rain. Choose one that packs into its own pocket.
- Waterproof day bag or dry bag: A 10-litre dry bag (100 THB from Chatuchak) protects your phone, wallet, and camera during downpours or boat trips.
- Waterproof sandals: Sport sandals with good grip are ideal for rainy days. Flip-flops are fine for the beach but slippery on wet Bangkok pavements.
- Sunscreen: SPF 50+ is essential. Bangkok sun is intense even on cloudy days. Apply every 2-3 hours if you're outdoors.
- Sunglasses and a hat: A wide-brimmed hat or cap protects against direct sun during temple visits and market walks.
Health and Toiletries
Bangkok has excellent pharmacies (Boots and Watsons are everywhere), but these items are worth packing from home:
- Mosquito repellent: DEET-based (20-30%) or picaridin formula. Mosquitoes are active at dawn and dusk, especially near canals and parks.
- Oral rehydration salts: Heat and humidity cause dehydration faster than you expect. ORS sachets are lightweight insurance.
- Basic first aid: Plasters, antiseptic wipes, ibuprofen, anti-diarrheal tablets. Street food is generally safe, but stomach upsets happen.
- Hand sanitiser: Useful before eating street food where hand-washing sinks may not be available.
- Prescription medications: Bring enough for your trip plus a few extra days, in original packaging with a copy of the prescription.
- Insect bite cream: Hydrocortisone or antihistamine cream for the bites you couldn't prevent.
Boots and Watsons pharmacies are on almost every major street and inside every mall. You can buy most over-the-counter medications cheaply without a prescription.
Electronics and Accessories
A few key gadgets and accessories will make your trip smoother:
- Universal power adapter: Thailand uses 220V with Type A, B, and C sockets. A universal adapter covers all bases. Most hotel rooms have at least one USB charging port.
- Portable power bank: 10,000-20,000 mAh keeps your phone charged through a full day of maps, photos, and Grab rides.
- eSIM or local SIM card: An eSIM (Airalo or similar) gives you data from the moment you land. Alternatively, buy a tourist SIM at the airport from AIS, DTAC, or True for 299-599 THB (7-15 days of unlimited data).
- Lightweight day bag: A small crossbody bag or packable daypack for daily sightseeing. Anti-theft features (hidden zips, slash-proof straps) are nice but not essential.
- Waterproof phone pouch: Useful for boat trips and absolutely essential during Songkran (water festival in April).
- Earplugs and sleep mask: Bangkok is loud. If you're staying near Khaosan Road or Sukhumvit, earplugs will help you sleep.
Thailand uses 220V electricity. If you're coming from a country with 110V (like the US), check that your devices support dual voltage (most phone chargers and laptops do). Hair dryers and straighteners may need a voltage converter.
What NOT to Pack
Save space and leave these items at home:
- Heavy jeans: Too hot and take forever to dry. Lightweight trousers do the same job.
- Expensive jewellery or watches: Unnecessary risk in crowded markets. Leave valuables in your hotel safe.
- Bulky towels: Every hotel and hostel provides towels. A compact microfibre towel is enough for emergencies.
- Too many shoes: One pair of comfortable walking shoes and one pair of sandals is all you need.
- Formal clothing: Bangkok is casual. Even upscale rooftop bars only require closed-toe shoes and smart-casual clothing — no suits or cocktail dresses needed.
- A full pharmacy: 7-Eleven and Boots are on every corner. Buy toiletries locally instead of packing full-size bottles.
- Drone: Drones are heavily regulated in Thailand and banned near temples and the Grand Palace. Leave it at home unless you have a permit.
Thailand has strict drug laws. Do not pack any recreational substances, including cannabis edibles or vape cartridges containing THC. Penalties are severe.
