The honest brief
Thailand is the easiest hard country to travel in. The infrastructure is excellent, the food is the best argument for the country, the people are extraordinarily patient with foreigners, and the smile that's coming at you is doing a lot of cultural work you may not be aware of. There are at least six smiles, ranging from 'delighted' to 'I am hiding extreme displeasure.' Reading the wrong one is the silent way first-time visitors give offense.
Bangkok is not the country. Bangkok is the front door. Most of what people remember from Thailand happens in the islands of the south (Krabi, Koh Lanta, Koh Tao) or in Chiang Mai and the cooler north. Build a trip that's two stops minimum: Bangkok 2–3 nights as launch pad + one beach or northern leg of 5–7 nights.

Country facts
When to visit
November through February is the dry season — coolest in the north (Chiang Mai gets 12°C nights in December, a surprise that most travelers underdress for), driest in the south, the country at its tourism peak. March–May is the burning season — northern Thailand has serious air quality problems from agricultural burns; Chiang Mai's AQI hits 200+ daily in March. Avoid the north then.
Monsoon (June–October) is fine in Bangkok, mixed on the Andaman (west) coast, and increasingly the smart move on the Gulf (east) side — Koh Samui's wettest month is actually November, inverted from the Andaman pattern. Two coasts, two weather calendars.
Money
Cash for street food, markets, taxis, tuk-tuks — most are now PromptPay-only via the Thai banking app, which foreigners can't easily use, so 100-baht and 500-baht notes do the work. Cards in hotels and mid-range restaurants. ATMs charge 220 baht ($6) per withdrawal — pull large amounts, fewer times.
Tipping: 20–50 baht for sit-down meals, the change rounded up for taxis, nothing for street food. The classic Bangkok scam: 'the Grand Palace is closed today, let me take you to a special gem shop' — the Palace is open, the gems are glass. Walk to the gate yourself.
Food + dining etiquette
Spoon and fork, not chopsticks (except for noodles). The spoon is the eating utensil; the fork pushes onto the spoon. Sharing is the default — order 4–5 dishes for a table of 3, rice in the middle. Don't ask for things 'spicy' as a foreigner — what they hear is 'authentic-spicy' and you will not finish the meal. Pet nit noi (a little spicy) is the calibration phrase.
Pad Thai is a tourist dish more than a Thai everyday dish; if you're at a place that serves it next to som tam (papaya salad), tom yum, and grilled river fish, eat anything except the Pad Thai. The food court at MBK in Bangkok is not a downgrade; it's the move.
Speaking the language
Sawatdee kha (women) or sawatdee khrap (men) is hello and the kha/khrap at the end of any sentence is a politeness particle that radically softens the request. Khop khun kha/khrap is thank you. Mai pen rai is 'no problem' / 'don't worry about it' and is the national mood — Thailand is a mai pen rai country and carrying that energy yourself goes far.
Don't touch anyone's head, including children's. Don't point your feet at a Buddha image or another person — sit with feet tucked back. The royal family is genuinely sacred; jokes are illegal (lèse-majesté), and visibly so among locals.

What to pack
Lightweight, long-sleeve everything for sun protection — the UV is punishing year-round. A long skirt or trousers and a covered shoulder shirt for temples (Wat Phra Kaew enforces this; they'll lend you a wrap but it's hot and not yours). Bug spray with DEET for islands and forest hikes; the malaria-carrying mosquitoes are the rural-night ones. Flip-flops, a real pair of trail sandals, and one closed shoe for cities.
Getting around
Bangkok BTS Skytrain + MRT subway covers most of what tourists want; the boats on the Chao Phraya are scenic and a real commute. Taxis: meter ('mee-teu' yes, otherwise the price is invented). Grab (the Uber of SE Asia) works and is honest.
Between cities: the overnight train Bangkok–Chiang Mai is romantic but slow (14h). Domestic flights on AirAsia/Nok Air/Thai Smile are cheap and 1h15. To the islands: fly to Krabi or Phuket, then ferry.
Where to actually go
One-week first trip: Bangkok 3 + Chiang Mai 4, or Bangkok 3 + one beach (Krabi or Koh Lanta) for 4–5. Two weeks: Bangkok + Chiang Mai + an Andaman island. Skip first trip: Pattaya (unless you specifically know why you're going), the deep south (Yala/Pattani — security concerns), Phuket itself (the islands around it are better than the island).
Common mistakes
Asking for spicy and then regretting it loudly. Buying the Grand Palace 'closed' story. Wearing a tank top into a temple. Tipping American-style and offending nobody but making everyone slightly confused. Refusing to take off shoes anywhere. Trying to do Bangkok + Phuket + Chiang Mai in five days.
Notes for the diaspora
If your family is Thai or Thai-Chinese, the temple your yai (grandmother) prays at probably has a thep (god) you've never heard the English name of — bring a list of family members and the abbot can write the wish in Pali script for the ceremony. Most Thai-Chinese families keep a Mandarin name and a Thai name; knowing both opens conversations.
Cultural notes
- Don't touch anyone's head — it's the most sacred body part
- Don't point feet at people or Buddha images — feet are lowest/dirtiest
- Wai (palms together, slight bow) instead of handshakes for elders
- Always remove shoes entering homes and temples
- Never disrespect the royal family — it's illegal (lèse-majesté)
Universal courtesies
- Try a greeting in the local language even if it's the only word you know — it's appreciated everywhere.
- Match local dress norms when entering religious sites, government buildings, or rural areas.
- Ask before photographing people, especially children or in religious settings.
- Tipping customs vary — never assume your home country's expectation applies.
- Remove shoes when entering homes if your host does; watch their cue.
- Keep voices lower than at home in temples, mosques, museums, public transport.
- Hands and gestures mean different things across cultures — observe before reaching out.
- Cash + cards: rural areas often need cash; major cities take cards. Carry small notes.
- Don't compare countries to each other in front of locals — every culture stands on its own.
- If you don't know the etiquette, watching for 30 seconds usually teaches it.
