Visas, seasons, money, health, transport, etiquette — the honest answers, updated for 2025.
Thailand extended its visa-exempt policy significantly in 2024–2025. As of mid-2025, citizens of most Western nations — including the USA, UK, all EU member states, Australia, New Zealand, and Canada — are granted 60 days visa-free on arrival, with a possible 30-day extension at an immigration office inside Thailand (fee: ฿1,900). You do not need to apply in advance for this.
If you plan to stay longer or want certainty before you travel, Thailand's e-Visa system (thaievisa.go.th) allows you to apply for a Tourist Visa from home. Processing typically takes 3–5 business days. The standard tourist visa (TR) grants 60 days per entry with a double-entry option available.
The arrival card (TM6) has been phased out digitally at Bangkok's Suvarnabhumi (BKK) and Don Mueang (DMK) airports — you now complete the immigration process via a digital kiosk or officer interview. Regional airports may still use paper TM6 forms. Keep your departure card safe: you surrender it when you leave.
Thailand has three distinct seasons, though the timing and intensity vary significantly by region. The country is broadly split into a northern plateau/central plain zone and two southern coastal zones — each with their own weather window.
The most popular time to visit. Temperatures range from 20–32°C, humidity is low, and rain is rare outside the deep south. Ideal for all regions. Book accommodation well in advance for December–January.
Temperatures push 35–40°C in central Thailand. It's bearable with air-con and pools, and prices are lower. Chiang Mai experiences severe haze from agricultural burning March–April. The islands remain good.
Lush green landscapes, dramatic skies, and far fewer tourists. Rain usually comes in intense afternoon showers, not all-day downpours. Prices drop 20–40%. Some remote mountain roads become difficult.
Southern Thailand coastal note: The Gulf Coast (Koh Samui, Koh Tao, Koh Phangan) has its own wet season running October–December, when the Andaman Coast (Krabi, Phuket, Koh Lanta) is dry and calm. Plan accordingly if you want island time.
Thailand's currency is the Thai Baht (THB / ฿). As of mid-2025, the exchange rate hovers around ฿34–35 per USD, ฿44–45 per GBP, and ฿37–38 per EUR. Rates fluctuate, so check a live rate (XE.com or Google Finance) before you travel.
ATMs are available everywhere — airports, 7-Elevens, malls, and even small towns. Most charge a flat fee of ฿220 per withdrawal regardless of amount, so withdraw larger amounts less frequently. Foreign-bank fee on top of this is common — check with your bank. Avoid Dynamic Currency Conversion (DCC): when the ATM asks "charge in USD/GBP" or "charge in THB" — always choose Thai Baht. Choosing your home currency routes you through the machine's poor exchange rate.
Cash is still king in Thailand's markets, street food stalls, tuk-tuks, temples, and smaller guesthouses. Always carry small bills — ฿20, ฿50, and ฿100 notes. Most mid-range and upscale restaurants, hotels, and shopping malls accept Visa and Mastercard. American Express acceptance is spottier outside Bangkok.
On tipping culture: it is not embedded the way it is in the US. That said, it is genuinely appreciated. In sit-down restaurants: rounding up or leaving ฿20–50 is standard. Tour guides and drivers: ฿200–400 per day. Hotel porters: ฿20–50 per bag. Hand cash directly rather than leaving it on the table.
Thailand requires no mandatory vaccinations for entry from Western countries. However, doctors typically recommend Hepatitis A and B, Typhoid, and ensuring routine vaccines (MMR, tetanus-diphtheria) are current before travel. If you plan to spend time in rural areas, national parks, or caves, rabies pre-exposure and Japanese encephalitis vaccines are worth discussing with your travel clinic.
Do not drink tap water in Thailand — this applies everywhere, including Bangkok. Sealed bottled water costs ฿7–10 at any 7-Eleven. In environmentally conscious accommodation and on tours, filtered water refill stations are increasingly common. Ice is generally safe in modern restaurants and hotels (it comes from commercial factories).
Healthcare in Thailand's major cities is genuinely world-class. Bangkok Hospital, Bumrungrad International, and Samitivej hospitals in Bangkok and their regional affiliates in Chiang Mai, Phuket, and Koh Samui are internationally accredited with English-speaking staff. Expect efficient service and costs far lower than the US or UK. Many accept international insurance directly.
For sun and heat: Thailand's UV index regularly hits 10–12 (extreme). SPF 50+ sunscreen, reapplied every 90 minutes, is not optional — it's basic survival. Carry water constantly. Heatstroke is a real risk in March–May; schedule outdoor activity for mornings or late afternoon, and give yourself a few days to acclimatise on arrival.
Thailand's domestic transport network is extensive and generally good value. Domestic flights are the fastest and often cheapest option for longer routes — Bangkok to Chiang Mai takes 1 hour versus 11 hours by bus. Budget carriers AirAsia, Nok Air, Thai Lion Air, and the premium Bangkok Airways connect all major cities and islands. Fares can be ฿500–1,500 booked in advance (comparable to a budget meal in Europe).
Night trains run by State Railway of Thailand (SRT) are a scenic and surprisingly comfortable option for Bangkok–Chiang Mai or Bangkok–Surat Thani (gateway to the southern islands). Book sleeper berths at least 2 weeks ahead via the SRT website or 12Go Asia. They are safe, iconic, and a genuine travel experience — you go to sleep and wake up somewhere new.
In cities, Grab (the regional Uber equivalent) is reliable, metered, and safe — use it instead of negotiating with tuk-tuks, which typically charge tourists 3–5x the fair rate. In Bangkok, the BTS Skytrain and MRT metro cover most tourist areas efficiently.
Rented motorbikes are popular in tourist areas but are the single biggest cause of tourist hospitalisations in Thailand. If you insist: always wear a helmet, avoid driving at night, and check that your travel insurance covers motorbike accidents (many policies exclude them).
Thailand is one of the world's most welcoming tourist destinations, and Thais are generally patient with cultural missteps. That said, a little awareness goes a long way toward genuine interaction — and avoids a few situations that can cause real offence.
Thai culture generally values sanuk (fun) and jai yen yen (cool heart — keeping calm). Visible anger or loud confrontation makes everyone uncomfortable and achieves nothing. If something goes wrong, a calm smile and a gentle request will nearly always get you further than frustration.
Thai is a tonal language written in its own script — it is genuinely difficult to learn quickly, and mispronouncing a tonal syllable changes the meaning entirely. The good news: English is widely spoken in tourist areas, in hotels across all price ranges, at airports, and by most service industry workers in Bangkok and Chiang Mai.
Outside the tourist circuit — in the Isan (northeast) region, rural northern villages, and smaller provincial towns — English is sparse. This is where a local driver or guide becomes not just convenient but genuinely necessary for meaningful interaction.
Google Translate handles Thai surprisingly well. Download the Thai language pack for offline use before you arrive — it is invaluable for reading menus, street signs, and pharmacy labels.
Five phrases that will earn you goodwill everywhere:
| English | Thai | Phonetic | Notes |
|---|---|---|---|
| Hello / goodbye | สวัสดี | Sawatdee (krap/ka) | Add "krap" if male, "ka" if female |
| Thank you | ขอบคุณ | Khob khun (krap/ka) | Most-used phrase |
| How much? | เท่าไหร่ | Tao rai? | Essential at markets |
| Not spicy! | ไม่เผ็ด | Mai phet | Lifesaving at Thai restaurants |
| Toilet / bathroom | ห้องน้ำ | Hong naam | "Naam" means water; points accepted |
Thai food is one of the great culinary traditions of the world — and eating your way through Thailand is itself a reason to visit. The diversity is staggering: from delicate jasmine-rice dishes in the north to fiery southern coconut curries, each region has its own identity.
Vegetarian and vegan travellers are well catered for in cities. Two terms matter: "Jay" (เจ) means strict Buddhist veg — no meat, fish, eggs, dairy, or pungent vegetables (onion, garlic). "Mangsawirat" (มังสวิรัติ) means vegetarian (no meat/fish but may include eggs and dairy). Many restaurants have Jay menus, especially around Buddhist holidays.
Street food safety: busy stalls with high turnover are generally safer than quiet ones. Watch that meat is freshly cooked in front of you — not sitting out in the heat. The classic backpacker rule holds: if the locals are eating there, it is probably fine. Upset stomachs in the first few days are common as your gut adjusts, not necessarily a sign of food poisoning.
Regional highlights worth seeking out:
Yes — Thailand consistently ranks among Southeast Asia's safest destinations for solo travel, including women travelling alone. The main risks are petty theft in crowded tourist areas (pickpockets around busy temples and night markets) and road accidents — Thailand has one of the world's highest road fatality rates, mostly involving motorbikes. Use common sense: keep valuables secured and avoid unlicensed taxis at night.
Tourist Police are active in all major tourist areas and can be reached 24/7 on 1155. Most tourist zones have visible police presence. The biggest threat most solo travellers face is being overcharged for rides or entrance "tickets" — a mild inconvenience, not a danger.
Tipping is not mandatory in Thailand — it is not embedded in the culture the way it is in the US. There is no expectation at street food stalls or local noodle shops. In sit-down restaurants, rounding up or leaving ฿20–50 is common and appreciated. For tour guides, ฿200–400 per day is the standard. For private drivers, ฿150–300 per day is typical. Hotel porters: ฿20–50 per bag.
One cultural note: always hand cash directly rather than leaving it on the table. And never tip with coins — it reads as dismissive.
Pack light — Thailand's heat makes heavy luggage miserable, and laundry services are cheap and fast everywhere (฿50–80/kg for same-day wash and fold).
Yes, absolutely. There is no Buddhist prohibition on women visiting temples while menstruating. Claims to the contrary are sometimes misattributed to Hindu traditions or localised folk beliefs not representative of mainstream Thai Buddhist practice.
The universal rules — covered shoulders and knees, shoes off, respectful behaviour — apply equally to everyone. You are welcome at any Buddhist temple in Thailand regardless of your cycle. If in doubt at a specific site, you can always quietly check with the temple staff.
Bring a doctor's letter in English for any prescription medication, especially if it contains controlled substances — opioids, benzodiazepines, stimulants (including ADHD medication like Ritalin or Adderall), and some sleeping pills. Keep all medication in original, labelled containers.
Thailand has strict narcotics laws. Even small amounts of certain substances — including some that are legal prescriptions elsewhere — can lead to arrest. The doctor's letter is your protection.
Many common medications (paracetamol, antihistamines, antidiarrheals, antibiotics) are available over the counter at pharmacies like Boots and Watsons at very low cost. Do not rely on this for specialised or controlled prescriptions.
