Safety Tips
Thailand is generally very safe for tourists. The main concerns are petty crime (bag snatching from motorbikes in cities), common tourist scams (gem stores, tuk-tuk tours, jet ski damage claims), and road safety. Use reputable taxi services or Grab. Avoid demonstrations, which occasionally occur in Bangkok. Some border areas have travel advisories.

Tipping
Tipping is not traditionally Thai but has become expected in tourist areas. In restaurants, 10% is appreciated if service charge isn't included; otherwise, leaving the small change is sufficient. Tip massage therapists 50-100 baht, hotel porters 20-50 baht, and tour guides 10% of the tour cost. Round up taxi fares or add 20 baht for good service.

Mobile/SIM
Buy a tourist SIM at the airport immediately upon arrival - booths from AIS, DTAC, and True are in the arrivals hall. Tourist packages with generous data (15-30GB) cost 300-600 baht for 8-15 days. Registration requires your passport. Coverage is excellent throughout the country. Alternatively, get an eSIM before arrival through providers like Airalo.
Getting There
Main Airports
Chiang Mai (CNX) ยท Bangkok (DMK) ยท Phuket (HKT) ยท Bangkok (BKK)
Airport Transfers
Suvarnabhumi (BKK): Airport Rail Link to downtown (45 baht, 30 minutes to Phaya Thai, then connect to BTS). Metered taxis from level 1 cost 300-500 baht plus tolls. Grab pickup from designated area. Don Mueang (DMK): A1/A2 buses to BTS Mo Chit (30 baht). Taxis cost 250-400 baht. For both airports, always use official taxi stands and insist on the meter.
Local Transport
Bangkok has excellent public transit: BTS Skytrain, MRT metro, and an extensive bus network. Grab is the dominant ride-hailing app and is safer than street taxis. Domestic flights are affordable - book on Air Asia, Nok Air, or Thai Lion Air. Intercity buses range from basic to VIP sleepers. Trains are scenic but slow. Songthaews and tuk-tuks are fun for short trips.
Culture & Travel Tips
Best Time to Visit
Thailand has three seasons: cool (November-February), hot (March-May), and rainy (June-October). The cool season is generally best for most of the country - comfortable temperatures and minimal rain.
Bangkok and Central Thailand are pleasant November through February. March-May brings intense heat (95ยฐF+/35ยฐC+). The rainy season brings daily downpours but also lower prices and fewer crowds.
The beaches have different optimal times. The Gulf Coast (Koh Samui, Koh Tao) has its driest weather February through June - they receive rain when the Andaman Coast is dry. The Andaman Coast (Phuket, Krabi, Phi Phi) is best November through April when monsoons subside.
Northern Thailand (Chiang Mai, Chiang Rai) is best November through February for trekking and cool mountain air. The burning season (March-April) brings severe air quality issues from agricultural fires.
The islands vary - some shut down or reduce services during off-peak monsoon months. Check specific islands before booking.
Cultural Notes
The Thai King is revered and protected by strict lรจse-majestรฉ laws. Never criticize, mock, or damage images of the monarchy. Disrespect carries serious legal consequences.
Buddhism shapes daily life - monks have elevated status, Buddha images are sacred (not decorations), and temples are places of worship first. Feet are low and heads are high - don't point feet at people or Buddha images.
'Saving face' is crucial - public confrontation or visible anger causes everyone to lose face. Stay calm even when frustrated. Smile, even when annoyed.
The wai (prayer-like greeting) has rules: younger/lower status initiates, hands higher shows more respect. When in doubt, return a wai you receive. Don't wai service workers (they wai you).
Thai people are genuinely friendly but the tourism industry means some interactions are transactional. Moving beyond tourist zones reveals authentic Thai warmth.
LGBTQ+ travelers are generally welcome - Thailand has visible gay culture, particularly in Bangkok and tourist areas. However, legal protections lag behind social acceptance.
Insider Tips
The Thai Baht is relatively stable. ATMs are everywhere but charge 220 THB per withdrawal - withdraw larger amounts less frequently. Cards work in malls and tourist areas; cash is needed elsewhere.
Negotiate tuk-tuk and taxi fares before getting in - meters are often 'broken.' Grab (Southeast Asia's Uber) is reliable and shows prices upfront. BTS/MRT in Bangkok is excellent.
The Grand Palace and major temples require covered shoulders and knees - carry a scarf or sarong. Shoes come off when entering temples and homes.
Street food is generally safe at busy stalls - high turnover means fresh food. Point and order; vegetarian options exist but are less common than in Western countries.
Scams exist: gem shops, friendly strangers offering tours, tuk-tuk drivers with 'special deals.' Be skeptical of strangers who approach you. If it seems too good to be true, it is.
Pharmacies stock most medications without prescriptions and prices are low. Stock up on anything you might need.
Dress Code
Casual dress fine. Cover shoulders/knees at temples. No shorts at Grand Palace.
Frequently Asked Questions
Do US citizens need a visa to visit Thailand?
US citizens can enter Thailand without a visa for tourism for up to 30 days if arriving by air. This is a visa exemption, not a visa on arrival. Your passport must be valid for at least 6 months from your entry date. You should be able to show proof of onward travel (a flight out of Thailand) and may be asked to demonstrate sufficient funds (20,000 THB per person or equivalent). For stays longer than 30 days, you can apply for a tourist visa at a Thai embassy or consulate before traveling.
Can I extend my stay beyond 30 days in Thailand?
Yes, you can extend your visa-exempt stay once for an additional 30 days (total 60 days) by visiting a Thai Immigration office and paying a fee of 1,900 THB. Apply a few days before your current permission expires. Bring your passport, a passport photo, a copy of your passport and departure card, and the completed application form. The Bangkok Immigration office can be crowded, so arrive early. For longer stays, consider obtaining a 60-day tourist visa before arrival, which can also be extended once for 30 days.
Is it safe to travel in Thailand?
Thailand is generally very safe for tourists and welcomes millions of visitors annually. Petty crimes like pickpocketing and bag snatching occur in tourist areas and on public transport, especially in Bangkok. Be cautious of common scams targeting tourists, such as gem scams, tuk-tuk scams offering suspiciously cheap tours, and jet-ski damage scams in beach areas. Use reputable tour operators and licensed taxis or rideshare apps. The southern border provinces near Malaysia have travel advisories due to unrest and should be avoided. Thai people are generally friendly and helpful toward tourists.
What should I know about Thai customs and etiquette?
Thai culture has important customs to respect. The Thai Royal Family is deeply revered, and disrespecting them (including defacing currency bearing the King's image) is illegal with severe penalties. Buddhism is central to Thai life. Dress modestly at temples (cover shoulders and knees), remove shoes before entering temple buildings or homes, and never touch or point your feet at Buddha images. The head is considered the highest part of the body (don't touch people's heads), and feet the lowest (don't point feet at people). The traditional greeting is the "wai" (palms together with a slight bow).
