Do I need a visa for Thailand?

Many nationalities (US, UK, EU, Australia, etc.) can enter Thailand visa-free for 60 days for tourism. This was extended from 30 days in 2024. Always check the Thai Ministry of Foreign Affairs for the most current rules for your specific passport.

Is tap water safe to drink in Thailand?

No — tap water in Thailand is not safe for drinking. Always use bottled water or filtered water for drinking and brushing teeth. Bottled water is cheap and widely available everywhere.

What's the best time to visit Thailand?

November to February is the coolest and driest season — the most popular time to visit. March to May is hot and dry. June to October is the rainy/monsoon season with lower prices and fewer crowds. Pack accordingly — TripPack pulls real weather data for your exact travel dates.

What should I wear to Thai temples?

Cover shoulders and knees — no tank tops, shorts, or short skirts. Long pants or a below-knee skirt plus a t-shirt with sleeves works. Some major temples (like Wat Phra Kaew) provide wrap-around cloths, but smaller temples don't. Carry a sarong or light scarf as a backup.

Is Thai street food safe to eat?

Generally yes — look for stalls with high turnover and food cooked fresh in front of you. Avoid raw vegetables and ice from unknown sources outside Bangkok. Bring basic stomach medication (Imodium, Pepto-Bismol) as a precaution. Tap water is not drinkable — stick to bottled or filtered.

Do I need a visa for Thailand?

Most Western passport holders get 30 days visa-free on arrival (60 days if entering by air for some nationalities). For longer stays, apply for a 60-day tourist visa before departure. Overstaying carries a 500 baht/day fine and potential ban.

What's the best SIM card for Thailand?

Buy a tourist SIM at any airport 7-Eleven or AIS/DTAC/TrueMove counter. 15-day unlimited data plans cost 299–599 baht ($8–17). AIS has the best coverage outside Bangkok. Registration requires your passport.

Thailand Packing List 2026 — What to Pack

What Should I Pack for a Trip to Thailand?

For Thailand, the most important items to pack are: a sarong or lightweight scarf (required for entry at all Buddhist temples including Wat Pho and Wat Phra Kaew), DEET insect repellent applied during daylight hours (dengue mosquitoes are active day and night, not just at dusk), lightweight breathable clothing (Thailand averages 28–35°C year-round — avoid denim and heavy cotton), reef-safe sunscreen, and stomach medication with rehydration salts (traveler's diarrhea is common for first-time visitors). Do not drink tap water. TripPack's Thailand packing list adjusts automatically for your season: cool-season (November–February), hot-season (March–May), or rainy-season (June–October).

🌡️ Heat & Humidity: Thailand is hot and humid year-round. Pack lightweight, breathable fabrics (linen, moisture-wicking synthetics). Avoid denim and heavy cotton.

🛕 Temple Dress Code: Temples require covered shoulders and knees. Pack a lightweight sarong, scarf, or carry a change of clothes. Many major temples sell cheap cover-ups at the entrance.

💊 Medications: Bring stomach medications (traveler's diarrhea is common), insect repellent with DEET (dengue mosquitoes are active during daytime), and reef-safe sunscreen. Pharmacies in Thailand are excellent and cheap, but availability of specific brands varies.

What Are the Essential Items to Pack for Thailand?

Lightweight breathable clothing (shorts, T-shirts, sundresses)
Sandals / flip-flops (easy on/off for temples)
Sarong or lightweight scarf (temple dress code + beach cover-up)
High-SPF reef-safe sunscreen
DEET insect repellent
Stomach medication (Imodium, rehydration salts)
Type A/B power adapter (Thailand uses 220V, Type A/B/C outlets)

What Should I Pack for Bangkok, Phuket, and Chiang Mai?

Thailand is large and diverse. What you pack depends heavily on where you're going — beach resort, city, or mountains.

🏙️ Bangkok: The capital is a city of extremes — brutal outdoor heat and aggressively air-conditioned malls and restaurants. Pack a light jacket or cardigan for indoor settings (sky trains, shopping centers, cinemas). Comfortable walking shoes are essential for exploring temples and street markets. Avoid heavy luggage — tuk-tuks and taxis are small.

🏖️ Phuket / Koh Samui / Islands: Reef-safe sunscreen is especially important around coral reef areas. Pack reef shoes or water sandals for rocky shorelines. A dry bag protects electronics on boat trips and rainy season downpours. Modest cover-ups are needed to enter beach towns' temples and markets.

🏔️ Chiang Mai / Northern Thailand: Significantly cooler than Bangkok and the south — especially December to February, when nights can drop to 10°C. Pack a light jacket and layer-able clothing. If you're doing trekking or jungle tours, add long sleeves and pants for mosquito protection and sun cover on exposed trails.

What Should I Pack for Thailand's Rainy Season (June–October)?

Thailand's monsoon season runs from June to October, with the heaviest rains typically in September and October. Traveling during this time is perfectly doable — prices are lower and crowds thinner — but your packing list changes significantly.

Packable rain jacket or poncho — daily afternoon downpours are intense but usually short (30–60 minutes)
Waterproof sandals — leather sandals and suede shoes will be destroyed
Dry bag or waterproof pouch — for phone and electronics during boat trips or sudden rain
Quick-dry clothing — humidity means wet clothes take forever to dry; synthetic fabrics are better than cotton
Extra insect repellent — dengue mosquito risk is highest during rainy season
Waterproof sandals with grip — wet temple steps and market streets become slippery

Note: Koh Samui and the Gulf of Thailand islands have a different monsoon pattern — their rainy season peaks in November–December, making them a good alternative when Phuket is wet in October.

Doing Thailand carry-on only? Laundry services at guesthouses cost just ฿50–100/kg, making light packing very practical. See the carry-on only packing guide for the 5-step method.

Common Mistakes to Avoid

Not packing modest clothes for temples — Shoulders and knees must be covered at all Thai temples; many enforce this strictly and turn visitors away.

Bringing expensive jewelry or watches — Unnecessary attention in markets and crowded areas; leave valuables at home.

Overpacking warm layers — Even "winter" in Chiang Mai rarely drops below 15°C at night; a light hoodie is enough.

Skipping mosquito repellent — Dengue is real; DEET-based repellent is essential, especially during rainy season (May–October).

Packing a huge suitcase for island-hopping — Longtail boats and speedboats have no luggage space; a backpack or small bag is far more practical.

How Much to Pack by Trip Length

1 week (multi-region)	4–5	2–3	2 pairs + flip-flops	Add temple-appropriate outfit
