Thailand Travel Tips and the Essentials Before You Fly
The Thailand travel tips that matter most. File the free Thailand Digital Arrival Card (TDAC) online up to three days before you arrive, don't drink the tap water, cover shoulders and knees at temples, never criticize the monarchy (lèse-majesté is a criminal offense), carry cash because street food and markets don't take cards, and use Grab instead of haggling with tuk-tuks. Vaping is illegal, Thai ATMs charge ฿250–350 per foreign-card withdrawal, and scooter accidents are the number one cause of tourist injury.
Thailand welcomes over 35 million visitors a year and the vast majority of trips are trouble-free. The 30 tips below, grouped by visas, money, health, etiquette, transport and connectivity, cover everything that separates a smooth trip from a frustrating one.
Key Facts (2026)
Entry is 30 days visa-free for 60 countries, plus a TDAC
The Thailand Digital Arrival Card is mandatory for everyone, it's free, and you file it at tdac.immigration.go.th up to three days before you arrive. Your passport needs 6+ months validity. The visa-free stay dropped from 60 days to 30 on 15 September 2026; one extension costs ฿1,900 for 30 more days.
Carry cash for everything small, and expect a ฿250–350 ATM fee
Street food, markets, tuk-tuks, temples and guesthouses are cash-only. Withdraw large amounts less often (max ฿20,000–30,000), use a Wise or Revolut card, and exchange at Superrich booths rather than the airport.
Don't drink the tap water
Bottled water is ฿7 at supermarkets. Use DEET repellent for dengue-carrying mosquitoes, which bite in daylight. Travel insurance isn't negotiable, because an uninsured hospital stay can cost $10,000–50,000+.
Cover up at temples, and never insult the monarchy
Shoulders and knees covered, shoes off, feet never pointed at a Buddha image. Lèse-majesté carries prison sentences, so don't joke about the royal family or deface banknotes. Stand for the royal anthem in cinemas.
Use Grab in cities and flights between regions
Grab is the reliable, metered option everywhere. Bangkok taxis start at ฿35 on the meter. Domestic flights cost ฿800–3,000 if you book 2–4 weeks ahead, and a berth on the overnight sleeper to Chiang Mai is ฿941–1,041.
Vaping and drugs are serious offenses
E-cigarettes are illegal to possess (fines and possible arrest). Drug offenses carry life sentences. Gambling is illegal. Scooter riders must wear a helmet, and most basic insurance policies exclude two-wheelers, so I wouldn't rent one without checking your cover.
Thailand Visa & Entry Rules
Visa-Free Entry
Citizens of 60 countries and territories (including the US, UK, EU, Australia, Canada, India, Japan, the Gulf states and most of Southeast Asia) get a 30-day visa exemption on arrival, halved from 60 days on 15 September 2026. The Thailand Digital Arrival Card (TDAC) is mandatory for everyone and must be filed at tdac.immigration.go.th up to three days before you arrive. Entry stamps are free. Never pay anyone at the border for a 'visa service'. See our full Thailand visa requirements guide for per-nationality rules.
Visa Runs & Extensions
A visa-free entry can be extended once by 30 days at any immigration office for ฿1,900, taking you to 60 days. 'Visa runs' (crossing a land border and re-entering) are still allowed but capped at two land entries per calendar year, and scrutinized if you do it repeatedly. For stays over a month, my advice is to apply for the Tourist Visa (TR) e-Visa before you travel, which gives 60 days on arrival, with the same 30-day extension on top.
Arrival Requirements
You'll need a passport valid for 6+ months, a return/onward ticket, and funds you can show if an officer asks. TAT lists ฿10,000 per person (฿20,000 per family) for visa on arrival and some visa-exempt entries, and the Royal Thai Embassy pages give ฿20,000 (฿40,000 per family) for the visa exemption, so I'd carry ฿20,000 or the equivalent in cash. You'll sometimes be asked for the round-trip ticket too. Complete the Thailand Digital Arrival Card (TDAC) online up to three days before you arrive to speed up immigration.
Prohibited Items
Thailand has strict drug laws. Any amount of narcotics can result in a life sentence or execution. E-cigarettes and vaping devices are illegal (fine and possible arrest for possession). Gambling is illegal. Obscene materials involving minors carry severe penalties. This isn't the place to test limits.
Cash, Cards, ATMs & Tipping in Thailand
ATMs & Currency
Thai bank ATMs charge ฿250 (about $7.50) per withdrawal on a foreign Visa card and ฿350 (about $10.50) on a Mastercard, so minimize fees by withdrawing larger amounts less frequently (max ฿20,000–30,000 per withdrawal). Wise and Revolut cards cut forex fees a lot. The Thai baht (฿) is the only currency widely accepted. USD exchange is available everywhere, but at poor rates.
Cards vs Cash
Major hotels, malls, and large restaurants accept cards. Street food, tuk-tuks, temples, local markets, guesthouses, and domestic transport are cash-only. Always carry ฿1,000–2,000 in small bills. The ฿1,000 note is hard to break at small vendors, so always request ฿100 and ฿500 notes when withdrawing.
Money Exchange
Superrich Thailand exchange booths (easily found near tourist areas and airports) consistently offer the best rates. I'd avoid airport exchange counters, where rates run a few percent worse than city center booths. Never exchange money with people approaching you on the street.
Tipping
It's not obligatory, but it's appreciated. In restaurants, round up or leave ฿20–50. A massage is ฿50–100, taxis and Grab expect nothing, tour guides ฿100–200 for a full-day tour, and a hotel bellhop ฿20–50 a bag. Don't tip at buffets or tourist-priced tourist restaurants where service charges are already added.
Health & Safety Tips for Thailand
Mosquitoes & Dengue
Dengue fever is present year-round in Thailand and there's no specific treatment, so prevention is everything. Use DEET-based repellent, especially at dawn and dusk. Aedes mosquitoes (dengue carriers) bite in daylight. Malaria risk is low in tourist areas but it exists in jungle/border regions. Consult a travel health clinic before departure.
Pharmacies & Medication
Thai pharmacies (easily found everywhere, look for a green cross) are excellent. Pharmacists can advise on common ailments and dispense many medications that require prescriptions in the West. Rehydration salts, antibiotics for traveler's diarrhea, antihistamines, and anti-nausea tablets are all cheap and readily available.
Travel Insurance
Non-negotiable. Thailand has excellent private hospitals but they charge significant fees to uninsured foreigners. Bangkok Hospital, Bumrungrad, and Samitivej are internationally accredited and excellent, but a serious injury or illness without insurance could cost $10,000–50,000+. Budget $3–8/day for comprehensive cover.
Road Safety
Traffic accidents are the number one cause of tourist deaths in Thailand. Always wear a helmet on scooters, and insist your rental shop provides one. Don't drink and drive. Be extremely cautious at night and on mountain roads. If there's an accident, the best hospital in any Thai city is usually Bangkok Hospital or a private facility, not the closest government hospital.
Thailand Do's and Don'ts for Culture & Etiquette
Respect the Monarchy
Thailand's lèse-majesté laws are strictly enforced, and criticizing the royal family can result in arrest and imprisonment. Don't make jokes about the royal family, don't deface currency (which bears the king's image), and stand for the royal anthem played at cinemas and public events.
Temple Etiquette
Cover shoulders and knees at all temples (carry a light scarf). Remove shoes before entering any temple building. Speak quietly. Never touch monks or point feet at Buddha images. Feet are considered the lowliest part of the body spiritually. Women must not hand objects directly to monks.
Understanding 'Face'
Thailand is a 'face' culture. Public embarrassment, confrontation, or raising your voice is deeply disrespectful and will get you nowhere. If something goes wrong, stay calm, smile, and work toward resolution quietly. The phrase 'mai pen rai' (never mind, it's fine) reflects an important Thai social value.
The Wai Greeting
The traditional Thai greeting is the wai, palms together, slight bow. As a tourist, you don't need to initiate wais, but returning one is polite. Never wai service staff or children (this reverses the hierarchy). The deeper and longer the wai, the more respect is being shown.
Getting Around Thailand by Flight, Train, Bus, Ferry & Grab
Domestic Flights
AirAsia, Nok Air, Thai Lion Air, and Thai VietJet connect Bangkok to all major destinations for ฿800–3,000 one-way if booked 2–4 weeks ahead. Bangkok–Chiang Mai and Bangkok–Phuket are the most competitive routes. Don Mueang airport handles most budget carriers, while Suvarnabhumi handles Thai Airways and Thai VietJet. Allow 2 hours for transfers between the two airports.
Trains
Thailand's rail network connects Bangkok to Chiang Mai (12–14 hours), Ayutthaya (about an hour), Kanchanaburi (3 hours), and southern hubs. The overnight sleeper to Chiang Mai is a classic. Train #9 leaves Krung Thep Aphiwat station (the renamed Bang Sue Grand, as long-distance trains no longer use Hua Lamphong) at 18:40, and a 2nd-class air-con berth is ฿941–1,041 via 12Go or the State Railway site. Trains are almost always late, so build buffer time into connecting plans.
Buses & Minivans
Long-distance buses are cheap and reliable. VIP 24-seat buses are the most comfortable (fully reclining seats, blankets, snacks). Book through 12Go.asia or at the bus terminal. Minivans are faster but less comfortable and sometimes driven recklessly, so sit near the back if you're nervous. For island destinations, combined bus+ferry tickets are available from Bangkok and most transport hubs.
Ferries & Boats
Ferries connect the mainland to all major islands. Seatran Discovery and Lomprayah are the main Gulf coast operators (Koh Samui, Koh Phangan, Koh Tao). Tigerline and Bundhaya run Andaman routes (Koh Lanta, Koh Lipe). Speed boats are faster but rougher in choppy seas, and car ferries are slower but more stable. Book the earliest departure when you're crossing during monsoon season.
Grab, Taxis & Tuk-Tuks
Grab (Southeast Asia's Uber) works in all major Thai cities and it's the most reliable, transparent option. In Bangkok, insist taxis use the meter. The starting fare is ฿35. Tuk-tuks are fun for short distances, but agree on a price before boarding (a typical Bangkok fare is ฿100–200 for short hops). Songthaews (red trucks) are the local transport in Chiang Mai. Flag one down and pay ฿30–40 for anywhere within the city.
Suvarnabhumi → Bangkok
Pre-book the airport-to-hotel leg
BTS, songthaews, and Grab cover in-city travel well, but the airport-to-hotel leg is where most first-timers overpay. 12Go sells fixed-price cars from every big airport, about ฿900–1,100 for a sedan from Suvarnabhumi into Bangkok, listed next to the shared vans and buses.

SIM Cards, Wi-Fi & What to Pack for Thailand
Thai SIM Cards
Buy a tourist SIM at the airport arrival hall. AIS and True (which now runs dtac) both have counters past customs. A 15-day unlimited data SIM costs ฿699 at either, and 8 days ฿499. AIS has the best rural coverage, TrueMove H the best city speeds. You'll need your passport. eSIM options (Airalo, Holafly) work but are usually more expensive for the same data allowance.
Wi-Fi Availability
Free Wi-Fi is available at virtually every café, restaurant, hotel, and 7-Eleven in tourist areas. Speeds are good (10–50 Mbps). Co-working spaces in Bangkok and Chiang Mai offer reliable 50–200 Mbps for ฿150–300/day. If you're working remotely, a Thai SIM with unlimited data is essential as a backup, because café Wi-Fi can be unreliable during peak hours.
Packing Essentials
Light, breathable clothing (cotton or linen). A light scarf for temple visits. Reef-safe sunscreen (SPF 50+). DEET mosquito repellent. A compact umbrella for rainy season. Universal power adapter (Thailand uses US-style 2-prong Type A/B plugs, but many outlets also accept European 2-prong). A dry bag for island hopping. Flip-flops for temples, easy on and off. A reusable water bottle.

Frequently Asked Questions
Common questions about Thailand Travel Tips.
No vaccines are legally required for entry (unless you're arriving from a yellow fever zone). Most travel health clinics recommend Hepatitis A, Hepatitis B, Typhoid, Tetanus-diphtheria, and for longer stays or rural travel, Rabies and Japanese Encephalitis. Consult a travel clinic 4–6 weeks before departure.
No. Tap water isn't safe to drink in Thailand. Bottled water is widely available and cheap (฿7 at supermarkets). Most guesthouses and hotels provide a free water bottle or refill station. Carry a reusable bottle and use refill points to cut down on plastic waste.
Cover shoulders and knees. Singlets, shorts above the knee and sleeveless tops aren't permitted. Most major temples (Grand Palace, Wat Arun) have sarongs to borrow or buy at the entrance. A light cotton scarf or shirt in your day bag solves this for any spontaneous temple visits.
Yes, at markets, street stalls, and with tuk-tuks. Fixed prices apply at 7-Elevens, malls, restaurants and metered taxis. At markets, starting at 60–70% of the asking price is reasonable. Stay friendly. Aggressive bargaining is considered rude, and don't bargain over items worth less than ฿50.
The most common is the 'gem store' scam (a 'friendly local' offers to take you to a government gem sale, and the 'gems' are worthless), tuk-tuk tours to overpriced shops, taxi drivers claiming your destination is closed, and ping-pong show touts who rope you into expensive bars. As a rule of thumb, if it sounds too good and a stranger started the conversation, it's a scam.
Do cover shoulders and knees at temples, remove shoes indoors, return a wai, carry cash, use Grab, and stay calm in disputes. Raising your voice loses face and gets nothing done. Don't criticize the monarchy, point your feet at people or Buddha images, touch anyone's head, touch monks, vape (it's illegal), drink the tap water, or ride a scooter without a helmet.
You don't need to bring much foreign cash. Withdraw baht from ATMs on arrival (฿250–350 fee per foreign-card withdrawal, so take out ฿20,000–30,000 at a time) or exchange at a Superrich booth in the city, not the airport. Carry ฿1,000–2,000 a day in small notes for street food, markets, tuk-tuks and temples, and use a card at hotels, malls and larger restaurants.
Yes, comfortably. $100 a day (about ฿3,300) sits above Thailand's mid-range budget of roughly $80 and buys boutique hotels or 4-star resorts on deals, restaurant meals with drinks, day tours, and Grab rides whenever you want them. Budget travelers manage on $30–45 a day, and in Chiang Mai or Pai, $100 a day borders on luxury.
