Thailand Travel Essentials

Visa on Arrival & Entry Requirements

Thailand offers visa-exempt entry for citizens of many countries. Most visitors can enter without a visa and stay for up to 30 days (extendable by 30 days at any immigration office for ฿1,900 / ~US$58). If arriving overland, the same 30-day allowance applies at most border crossings.

30-Day Visa-Exempt Entry

Citizens of the following countries can enter Thailand without a visa for up to 30 days with a valid passport (must have at least 6 months validity remaining):

Europe: All EU member states, United Kingdom, Switzerland, Norway, Iceland, Liechtenstein.

Americas: United States, Canada, Brazil, Argentina, Chile, Peru.

Asia-Pacific: Japan, South Korea, Hong Kong, Singapore, Malaysia, Indonesia, Philippines, Australia, New Zealand.

Middle East: Israel, UAE, Bahrain, Kuwait, Oman, Qatar, Saudi Arabia.

Africa: South Africa.

Visa on Arrival (VOA)

Citizens of countries not on the visa-exempt list — including India, China, Taiwan, and several Central Asian nations — can obtain a Visa on Arrival at major airports and land borders. The VOA allows a stay of up to 15 days and costs ฿2,000 (~US$61). Requirements include a passport photo, proof of accommodation, a return ticket, and proof of funds (฿10,000 per person or ฿20,000 per family in cash).

Tourist Visa (TR)

For stays longer than 30 days, apply for a Tourist Visa (TR) at a Thai embassy or consulate before travel. The single-entry TR allows 60 days (extendable by 30 days in-country). The multiple-entry TR (METV) is valid for 6 months with 60 days per entry.

Entry Requirements

• Passport validity: At least 6 months from date of entry.
• Proof of onward travel: Airlines may ask for a return or onward ticket. Immigration officers occasionally check.
• Proof of funds: Technically required — ฿10,000 per person (about US$303) or ฿20,000 per family. Spot checks are rare but do happen, especially at land borders.
• TM6 arrival card: Abolished in 2024 for air arrivals. Still required at some land border crossings.

Currency & Money Exchange

Thailand's currency is the Thai Baht (฿ or THB). Coins come in denominations of ฿1, ฿2, ฿5, and ฿10. Banknotes come in ฿20 (green), ฿50 (blue), ฿100 (red), ฿500 (purple), and ฿1,000 (brown/grey). The current exchange rate is approximately ฿33 to US$1.

Best Exchange Rates

Avoid exchanging money at airports — rates are significantly worse than in the city. The best rates in Bangkok are found at licensed exchange counters:

• SuperRich (green and orange branches) — consistently the best rates in Bangkok. Main branches at Ratchadamri (near BTS Chit Lom) and Khao San Road. SuperRich Green and SuperRich Orange are two separate companies — both offer excellent rates.
• Vasu Exchange — popular on Sukhumvit, near Nana BTS. Good rates for major currencies.
• X-One Currency Exchange — located in several malls including MBK and Siam Paragon.

Outside Bangkok, exchange counters in tourist areas (Phuket, Chiang Mai, Koh Samui) offer reasonable rates. Compare 2-3 counters before exchanging large amounts.

ATMs

ATMs are everywhere in Thailand — 7-Eleven shops, malls, airports, and on most tourist streets. All Thai ATMs charge a flat fee of ฿220 (~US$6.70) per withdrawal for foreign cards, on top of whatever your home bank charges. To minimize fees:

• Withdraw the maximum amount per transaction (typically ฿20,000-30,000 depending on the ATM).
• When the ATM asks "convert to your home currency?" — always select No. This avoids Dynamic Currency Conversion (DCC), which adds a 3-5% markup.
• Use a travel-friendly bank card with no foreign transaction fees (Wise, Revolut, Charles Schwab).

Cards & Mobile Payments

Credit and debit cards (Visa, Mastercard) are accepted at hotels, malls, chain restaurants, and larger shops. Smaller vendors, street food stalls, markets, and local transport are cash only. Carry cash for daily expenses — you will need it more often than cards.

Thai QR code payments (PromptPay) are everywhere, but these require a Thai bank account. Some restaurants accept Alipay and WeChat Pay. Apple Pay and Google Pay have limited acceptance.

SIM Cards & Internet

Thailand has excellent mobile coverage and fast 4G/5G internet across the country, including most islands. Getting a local SIM card is cheap and easy — buy one at the airport upon arrival for the best convenience.

Major Operators

• AIS — Thailand's largest network with the widest coverage, especially in rural areas and islands. Generally the best choice for travelers heading outside major cities.
• TRUE (formerly DTAC + TRUE merger) — Strong coverage in cities and tourist areas. Competitive pricing. Good 5G network in Bangkok.
• TRUE Move H — Budget-friendly option on the TRUE network.

Tourist SIM Packages

All operators sell tourist SIM packages at airport counters (arrivals hall, open 24/7 at Suvarnabhumi and Don Mueang). You will need your passport to register the SIM — this is a legal requirement in Thailand.

You can also buy eSIMs online before arrival through providers like Airalo, Holafly, or directly from AIS. eSIMs are data-only (no Thai phone number for calls/SMS) but avoid the queue at the airport counter.

Wi-Fi

Free Wi-Fi is available at most hotels, hostels, cafes, malls, and coworking spaces. Speed varies widely — budget guesthouses may have slow connections while coworking spaces and modern cafes typically offer 50-200 Mbps. 7-Eleven stores nationwide offer free Wi-Fi (connect and accept terms). Bangkok's BTS and MRT stations have free public Wi-Fi.

Safety Tips & Scam Awareness

Thailand is generally very safe for tourists. Violent crime against visitors is rare. The main risks are petty theft, traffic accidents (especially on motorbikes), and tourist-targeted scams. Use common sense and you will have a trouble-free trip.

Common Tourist Scams

• The Tuk-Tuk Scam: A friendly stranger or tuk-tuk driver tells you that the temple/palace you want to visit is "closed today" (for a "Buddhist holiday," "cleaning," etc.) and offers to take you to a "better" temple or a "special" shop instead. The destination is always a gem shop, suit shop, or travel agency where the driver earns a commission. How to avoid: Ignore anyone who tells you an attraction is closed. Walk to the entrance yourself and check.
• The Gem Scam: You are taken to a gem or jewelry shop (often by a tuk-tuk driver) and told you can buy gems cheaply and resell them at home for a huge profit. The gems are real but massively overpriced — often worth 10-20% of what you paid. There is no profit to be made. How to avoid: Never buy gems or jewelry from shops you were taken to by a driver or tout. If you want gems, go to a reputable dealer independently.
• The Suit Scam: A tailor shop offers an unbelievable deal — a custom suit for US$50-100. The suit is made quickly from cheap fabric with poor stitching. When you return home and it falls apart, you have no recourse. How to avoid: If a price sounds too good to be true, it is. Quality tailoring in Bangkok costs ฿8,000-25,000 (US$242-758) for a suit and requires 2-3 fittings over several days. Reputable tailors include Raja's Fashions, Pinky Tailor, and Marco Tailor.
• Jet Ski Damage Scam: Common in Phuket and Pattaya. After renting a jet ski, the operator claims you caused pre-existing damage and demands thousands of baht in compensation. How to avoid: Take detailed photos and video of the jet ski from every angle before renting. Better yet, skip jet skis entirely — the scam is well-documented.
• Taxi Meter Refusal: Bangkok taxi drivers sometimes refuse to use the meter and quote a flat fare (always higher). By law, metered taxis must use the meter. How to avoid: If a driver refuses the meter, get out and take the next taxi. Or use Grab (Southeast Asia's Uber equivalent) for fixed-price rides.

General Safety Tips

• Motorbike rental: The leading cause of tourist injuries and deaths in Thailand. If you rent a motorbike, wear a helmet (legally required), have a valid motorcycle license, and avoid riding at night. International Driving Permits are recognized. Travel insurance often excludes motorbike accidents if you are unlicensed.
• Drink spiking: Rare but not unheard of, especially at Full Moon Parties and in nightlife areas. Watch your drink, buy your own, and do not accept drinks from strangers.
• Lese-majesty law: Insulting or defaming the Thai monarchy is a serious criminal offense carrying up to 15 years in prison. This applies to spoken words, social media posts, and even sharing certain content. Respect the monarchy at all times.
• Drug penalties: Thailand has harsh drug laws. Possession of even small amounts of hard drugs can result in lengthy prison sentences. While cannabis was decriminalized in 2022, public consumption is frowned upon and regulations continue to evolve — follow local rules.
• Travel insurance: Strongly recommended. Medical care in Thailand is excellent but private hospital bills can be substantial. Bumrungrad, Bangkok Hospital, and Samitivej are world-class but charge accordingly. Ensure your policy covers emergency evacuation.

Weather & Best Time to Visit

Thailand has a tropical climate with three distinct seasons. Temperatures across the country stay warm year-round, but rainfall, humidity, and regional conditions vary significantly by season and location.

The Three Seasons

• Hot Season (March — May): The hottest time of year, with temperatures reaching 35-40°C (95-104°F) in Bangkok and the central plains. April is the peak of the heat. The famous Songkran water festival (April 13-15) provides welcome relief. Humidity is high but rainfall is minimal. Good for beaches but sightseeing in cities can be exhausting.
• Rainy Season (June — October): The southwest monsoon brings regular rainfall, usually in heavy afternoon downpours lasting 1-2 hours. Mornings are often sunny. Temperatures drop slightly to 28-33°C (82-91°F). September and October are the wettest months. Travel is still possible — prices are lower, crowds are thinner, and landscapes are at their greenest. Expect occasional flooding in low-lying areas of Bangkok.
• Cool Season (November — February): The most pleasant time to visit. Temperatures range from 20-32°C (68-90°F) with lower humidity and very little rain. Northern Thailand (Chiang Mai, Chiang Rai) can drop to 10-15°C (50-59°F) at night — bring a jacket. This is peak tourist season with the highest prices and most visitors, especially around Christmas, New Year, and Chinese New Year.

Best Time by Region

Overall best time: November to February offers the most comfortable weather nationwide. If visiting the Gulf islands (Koh Samui, Koh Phangan, Koh Tao), March to September is ideal since they follow a different monsoon pattern.

Tipping Culture

Tipping is not a strong cultural expectation in Thailand, but it is appreciated and increasingly common in tourist-facing businesses. Thais generally do not tip each other in everyday transactions, but service workers in the tourism industry have come to expect small tips from foreign visitors.

Tipping Guidelines

• Restaurants: At upscale restaurants, a 10% service charge is often included in the bill — check before tipping. At mid-range restaurants without a service charge, leaving ฿20-100 is a nice gesture. At street food stalls and local eateries, tipping is not expected.
• Hotels: ฿20-50 per bag for porters. ฿20-50 per day for housekeeping, left on the pillow or bedside table. Concierge staff who arrange tours or bookings: ฿50-100.
• Taxis and Grab: Rounding up to the nearest ฿10-20 is common. A ฿50 fare — hand over ฿60 and say "mai tong thorn khrap/ka" (no change needed).
• Massage and Spa: ฿50-100 for a traditional Thai massage (฿200-300/hour). ฿100-200 for a spa treatment at upscale venues. This is perhaps the one service where tips are most expected.
• Tour guides: ฿200-500 per day for a full-day private guide. ฿100-200 per person for group tour guides. Boat drivers and support staff: ฿50-100.
• Bars: Leaving small change (฿20-50) or rounding up is common at bars frequented by tourists. Not expected at local Thai bars.

Important: Always tip in cash, even if you pay the bill by card. Tips added to credit card payments do not always reach the staff.

Useful Thai Phrases

Thai is a tonal language with five tones, which makes pronunciation tricky for beginners. But even basic attempts at speaking Thai are warmly received — locals appreciate the effort. Men end sentences with "khrap" (ครับ) and women with "ka" (ค่ะ) as a polite particle.

Essential Phrases

Tip: The Thai greeting "wai" — pressing your palms together at chest level with a slight bow — is used when saying hello and thank you. Return a wai when someone wais you, but you do not need to wai children, service staff who wai you as part of their job, or monks (monks do not return wais from laypeople).

Emergency Contacts

Save these numbers in your phone before you arrive. All emergency numbers work from any Thai SIM card or landline, and operators at the Tourist Police hotline speak English.
