First trip to Thailand 2026: complete beginner’s checklist

A first trip to Thailand in 2026 is not “buy a tour and fly.” You need to prepare on six fronts: visa and TDAC, budget, money, transport, connectivity, safety, and health. This article is a complete checklist for travelers heading to Southeast Asia for the first time who want to avoid surprises at the border and overpaying on the ground. 🇹🇭

Entry rules are current as of September 2026, prices as of April 2026. Entry conditions, prices, and rules may change — check official sources before you fly. This applies especially to visa requirements, the cash amount required at the border, and insurance requirements.

When to go to Thailand for the first time

Thailand doesn’t have four seasons but two: high season (November–March) and low season (April–October). High season is dry, relatively cool (by Thai standards), and expensive. Low season brings rain and humidity, but accommodation and airfare prices drop noticeably.

If you’re traveling for the first time and want minimal weather risk, January and February are the most stable months across the country. Rain is nearly absent, the heat is easier to bear, and seas on both coasts are usually calm.

But there are subtle details that travelers often miss. In the north (Chiang Mai, Chiang Rai) heavy PM2.5 smog is common from February to April — locals burn their fields, and the sky turns into a milky haze. So if the north is on your list, December–January is the better choice. The south works differently: on the west coast (Phuket, Krabi) the rainy season runs from May to October, while on the east coast (Koh Samui, Phangan) the rhythm is different, with the main rains arriving in October–November.

By the way, rain in low season isn’t the gray blanket you get in Europe. Most often a downpour lasts an hour or two in the afternoon, and then the sun comes back out. Many travelers deliberately choose low season for lower prices and uncrowded beaches. The key is not to plan a beach holiday in Phuket during these months without a backup plan.

Where to go on your first trip: Bangkok, Phuket, or Pattaya

The three most popular entry points for beginners are Bangkok, Phuket, and Pattaya. Each has its own character.

Bangkok — the capital and the region’s main air hub. It’s not a beach destination but a big city with temples, markets, shopping malls, and nightlife. It’s convenient to arrive here first, since onward travel anywhere else is cheap. Downsides include traffic, noise, and big-city climate; there is no beach holiday here at all.

Phuket — Thailand’s largest island and best-known beach resort. It suits those who want a “classic” format: a hotel by the sea, beaches, island tours, and tourist infrastructure. It costs more than Pattaya and most other destinations, so a budget-conscious beginner will need careful planning.

Pattaya — closest to Bangkok (about two hours by car). Accommodation and food are cheaper than on the islands, the infrastructure is well developed, and many tours are within easy reach. The city’s reputation is mixed: it has a dense adult entertainment industry, and some areas look calm during the day but are very different at night. Families with children should choose accommodation carefully.

What to choose? If you’re traveling for the first time for 7–10 days and aren’t set on the beach, combine Bangkok with one resort (for example, Bangkok + Phuket). If it’s only beach time with no cultural program, choose Phuket or Koh Samui. More details on these places are covered in our guides to top attractions in Bangkok and top 10 places in Phuket.

Visa and documents for a first trip to Thailand in 2026

The most important section of this article. Mistakes are not an option here: visa errors get you turned back at the border. ✈️

Since September 15, 2026, the 60-day visa-free regime has been abolished. Holders of ordinary Russian passports may stay in Thailand without a visa for up to 30 days — under the bilateral agreement between Russia and Thailand. Citizens of Kazakhstan also enter without a visa for up to 30 days under their own agreement with Thailand, while citizens of Uzbekistan now need a visa obtained in advance. Those who entered before September 15 may stay until the end of the period already granted. You can extend your stay at an immigration office on site: under Thai rules, only once and for no more than 30 days, with a 1,900 baht fee, and the decision is made by the officer (the consular website of Russia’s Ministry of Foreign Affairs says that visa-free stays can be extended by one week only in special cases, so don’t plan your trip around an extension). Details are in our breakdown of visa-free entry to Thailand for 30 days · RU. If you plan to stay longer than a month, you’ll need to apply for a tourist visa — it allows up to 60 days per entry.

Since May 1, 2025, the TDAC digital arrival card has been mandatory. It’s the online version of the old paper form. It is filled out online for free within 3 days before arrival (the arrival day counts as one of those 3 days) on the official TDAC portal. Without TDAC confirmation, you’ll run into problems at the border: it’s best to print it out or save a screenshot on your phone.

Next, three documents without which even visa-free entry won’t work:

• A passport valid for at least 6 months on the date of entry. Otherwise, they’ll put you on the next flight home.
• A return ticket or a ticket to a third country. Border officers have the right to ask for it; without a ticket out of the country, you’ll be turned back.
• Proof of accommodation booking — sometimes asked for at the airline check-in counter.

Where can you get primary sources on visa rules? We recommend checking the official website of the Ministry of Foreign Affairs of Thailand — it publishes current rules for citizens of specific countries. Any article (including ours) can go out of date within a week, while the ministry’s website is updated faster.

The key rule: fill out TDAC no earlier than 3 days before arrival, and check your passport a month before your trip. If your passport has less than six months of validity left, get a new one early.

Budget for your first trip: where to save and where not to

The main budgeting trap is trying to plan everything “online” and choosing the cheapest option. Thailand’s price range is huge: you can live for a week on 30,000 rubles, or spend the same amount in a single day. So we start not with numbers but with a list of expense categories. 💰

The one figure you need to know from the start: 20,000 baht per person or 40,000 baht per family in cash to prove financial means at the border. Border officers have the right to ask you to show this money — not always, but they can. Bring a margin in cash: a card won’t count here.

Next, here are the expenses that will definitely go into your first trip budget:

• Flights. The biggest item; book in advance.
• Accommodation. The range runs from hostels to luxury hotels; prices vary by season and city.
• Food. Street food and food courts are several times cheaper than restaurants in tourist areas.
• Local transport. Metro, taxis, ferries, domestic flights, vehicle rental.
• Tours and activities. Islands, parks, shows, diving.
• Connectivity. SIM or eSIM for the whole trip.
• Insurance. We recommend including it in your budget (more on this in a separate section).
• Contingency reserve. 10–15% of the total budget for surprises.

Where shouldn’t you cut costs? On insurance, on accommodation for the first two nights (when you’re tired and disoriented), and on airport transfers late at night. Where you can save: on food (Thai street food is both cheap and authentic) and on domestic travel (buses and trains are cheaper than flights).

We break down specific accommodation and food costs in different cities in a separate guide to the cost of living in Thailand — the figures there are current.

What to bring: a beginner’s checklist 📋

No lengthy explanations here — a short list worth printing out and going through before you pack.

1. Passport valid for at least 6 months + copies (paper and in the cloud).
2. Printout or screenshot of TDAC.
3. Return ticket — printout plus a PDF on your smartphone.
4. Cash in USD or EUR + bank cards (see the money section for which ones).
5. Insurance policy — printed copy and a page on your smartphone with offline access.
6. Medicine kit: antihistamines, enterosorbents, products to restore water and electrolyte balance. Choose specific medications with your doctor.
7. Plug adapter for type A/B/C. Hotels have all three socket types.
8. Lightweight clothing + a sweater or rain jacket. Air conditioning in malls and buses runs at full blast — without long sleeves, you’ll freeze.
9. Comfortable slip-on shoes. At temples you take your shoes off at the entrance, and laces turn this into an ordeal.
10. Sun protection: SPF 50+ sunscreen, sunglasses, a hat.

What don’t you need to bring from Russia? Shampoo, toiletries, flip-flops — all of this is available at any 7-Eleven and costs next to nothing. But it’s better to bring your usual medications: equivalents in Thai pharmacies are sold under different names, and it’s hard to explain what you need to a pharmacist without English.

And one detail people forget: temples won’t let you in wearing shorts above the knee or tank tops with bare shoulders. If your wardrobe is all beachwear, pack at least one covered outfit (a T-shirt with sleeves and light trousers or a long skirt).

Money in Thailand: which cards work and where to get cash

The money situation in Thailand is specific for Russian travelers. The key rule fits in one sentence.

Mir payment cards do NOT work in Thailand. Not at ATMs, not in stores, not in hotels. There are no exceptions — forget about Mir as a payment method in Thailand in 2026.

What works? UnionPay cards issued by Russian banks are accepted inconsistently — they go through in some places and not in others. Some banks work better than others, so check before your trip and don’t rely on UnionPay as your only payment method. A backup plan is essential: either a second card from a friendly jurisdiction or cash in USD/EUR to exchange.

Thai ATMs charge a fixed fee for cash withdrawals on foreign cards — as of April 2026 data, it is 220 baht per transaction (the exact amount is the same at most banks, but check the screen before confirming). This is on top of any fee from your issuing bank. So the strategy is simple: withdraw rarely and in large amounts, not 2,000 baht every morning.

A workable setup for a first trip:

• Cash in USD or EUR — main reserve. Exchange at a bank or a licensed exchange office with transparent rates and a visible license (BoT) on the wall, not at a tourist shop with a “best rate” pitch.
• Backup foreign card — for online bookings and large purchases.
• Local cashless option — open a Thai bank account or use a PromptPay wallet once you’re there; suitable for trips longer than two weeks.

Local wallets are a separate story. Many foreigners use the local TrueMoney Wallet: top it up once, then pay by QR code like locals do. It’s handy for street food and small purchases where card terminals don’t work. The full setup for organizing payments, currency exchange, and cashless logistics is covered in the full guide to financial logistics · RU.

Bottom line: travel to Thailand with at least two independent payment methods — cash plus at least one working card. Don’t travel with a single card and hope for the best.

Transport: from the airport, around town, and between resorts

Thailand’s transport network is varied and generally convenient — the key is not to pay a tourist markup where local alternatives exist. ✈️

Most people fly into Suvarnabhumi — Bangkok’s main airport. The cheapest and fastest way downtown is the Airport Rail Link to Phaya Thai station (the fare is symbolic, around 45 baht as of April 2026; check the current price at the ticket counter or in the Bangkok ARL app). The train runs strictly on schedule and isn’t stuck in traffic. A taxi is an alternative, but during rush hour the trip takes one and a half to two times longer and costs much more.

In Bangkok, the basic taxi apps are — Grab, Bolt, InDriver. The price is visible upfront, the driver arrives at the address you set in the app, and you don’t need to haggle. A standard metered city taxi also works, but ask the driver to turn on the meter: “meter, please” — otherwise you’ll end up with a negotiated fare that favors the driver.

Motorbikes are a separate story. Renting a motorbike in Thailand requires an International Driving Permit with an open category A. Without an IDP this is technically illegal — if stopped by police, you’ll be fined, and insurance won’t cover an accident. Many rental shops hand out bikes without checking documents, but the responsibility is still yours. If you have no motorcycle riding experience, don’t learn on your first trip. Seriously. Local roads are no place for a debut.

Between cities and resorts, you can take:

• Domestic airlines (Thai AirAsia, Thai Airways, Nok Air) — fast, good for long routes like Bangkok–Phuket.
• Trains — slow, but cheap and atmospheric.
• Buses and minivans — the main intercity transport.
• Ferries — to the islands (Koh Samui, Phangan, Phi Phi).

A detailed breakdown of the capital’s city transport is in the guide transport in Bangkok. If you’re planning a beach holiday on an island, see the article about transport in Phuket.

Connectivity and internet: eSIM or a local SIM card

Internet is simpler than it seems. Wi-Fi is almost everywhere — in hotels, cafés, and shopping malls. But mobile data is essential for taxis, maps, translation, and staying in touch with loved ones.

eSIM is the most convenient way to get connected in 2026. You buy and activate it online before your flight, and by the time you land the internet already works — no need to hunt for a carrier office with a suitcase in hand. It works if your phone supports eSIM (most iPhones from the XS onward and recent Android flagships).

If your device only takes a physical SIM, get a local card. The three main carriers:

• AIS — the most consistent coverage nationwide, especially outside big cities.
• TrueMove H — the fastest speeds in Bangkok and other cities.
• DTAC — usually cheaper than the other two at comparable quality in tourist areas.

Where can you buy a local SIM? Three options: kiosks in the airport arrivals area, any 7-Eleven (passport required), or a carrier’s own office. The airport is convenient but more expensive — you’ll pay extra for a “tourist” package. 7-Eleven is cheaper but offers fewer plans. A carrier office has the widest selection and personalized setup.

What to bring for registration? Passport — required. Since 2024, all SIM cards in Thailand are registered to a specific person. Without a passport, you won’t be sold a SIM even at 7-Eleven.

Choosing a plan is a separate matter. Tourists usually need a 7–15 day plan with unlimited data and a small pool of minutes. For long stays, monthly plans are cheaper. For a full comparison of plans, carriers, and scenarios, see the guide mobile service and internet in Thailand.

Safety for beginners: laws, etiquette, and what you must never do

This is the most important section after the visa one. Thai laws are stricter for foreigners than they seem at first glance, and some travelers only learn about them at a police station.

The lese-majesty law (known as Article 112): any disrespectful act or statement — up to 15 years in prison. This is an absolute ban, with no compromises or jokes. No comments about the royal family, no disrespectful posts on social media from Thailand, no torn banknotes (banknotes feature the king). Article 112 applies to foreigners exactly as it does to Thais.

E-cigarettes and vapes are banned in Thailand for both import and use: importing them can bring up to 10 years in prison or a fine of five times the value of the goods (or both). This is the most common beginner mistake — travelers bring a vape without knowing about the ban. Vapes get seized at the airport, in tourist areas, and at resorts. The solution is simple: leave it at home.

Drugs — absolutely prohibited. Any amount, any “light” classification — these carry real prison sentences. No “just trying it.” Absolutely not.

Alcohol is sold only during 11:00–14:00 and 17:00–24:00. At other times, 7-Eleven cashiers simply won’t ring up beer — it’s the law, not a cashier’s whim. Rules at hotels and restaurants may be more lenient.

Temple etiquette:

• Shoulders and knees must be covered. Pareos and sarongs are sold at the entrance to major temples.
• Shoes come off before entering. That’s why comfortable slip-on shoes aren’t a whim but common sense.
• Don’t climb on or hug Buddha statues, or pose for photos with your back to them.

Body etiquette:

• The head is sacred — never touch someone else’s head, even as a joke. This applies to children as well.
• Feet are considered “dirty” — never point the sole of your foot at people or at Buddha statues. Don’t cross your legs when sitting across from a monk or in front of an altar.

And a customs detail for entry: you can bring in up to 1 liter of alcohol and no more than 200 cigarettes (or 250 grams of tobacco) duty-free. Exceeding these limits means a fine or confiscation.

For more on city risks (scammers, setups, “free” tours), see the full guide to safety in Thailand. And since Grab and vehicle rentals are the backbone of any trip, it’s also worth reading about road safety in Thailand.

Health and insurance: what’s essential and what you shouldn’t travel without

We recommend getting insurance before you travel. Public hospital treatment for foreigners is paid and not cheap. Private clinics are high quality, but the cost of a visit — and especially hospitalization — can easily run into tens of thousands of baht per day.

Travel insurance is our recommendation. What official lists say about it is in the section below.

What kind of policy suits a first trip:

• No deductible. Otherwise, you pay the first few thousand rubles yourself — and in a hospital, that gap turns into a surprise.
• Covers active recreation, especially motorbike riding. Check the terms of your chosen policy to see whether injuries from riding a scooter are covered, whether an additional option is needed, and what requirements apply to driving documents.
• Covers dengue fever. Dengue is a real risk in Thailand, and hospitalization for a severe case is expensive. Check whether dengue treatment is included in your chosen policy.
• With a minimum coverage amount around the level offered for Southeast Asia in current rankings.

Basic medicine kit for the tropics:

• Antihistamines — for bites, food allergies, and localized sun reactions.
• Enterosorbents — for digestive upset, a common issue in the first few days.
• Products to restore water and electrolyte balance — for food poisoning and heavy sweating.

Specific brand names are up to your doctor and pharmacist. It’s better to bring your usual medications from Russia, since equivalents in Thailand are sold under different names.

Other health things to know in Thailand:

• Dengue — spread by mosquitoes; protection against bites matters most.
• Overheating and heatstroke — in the first few days, don’t try to “fit everything in”; your body doesn’t have time to acclimatize.
• Drinking water — bottled only. Cylindrical ice with a hole in the center, which is delivered centrally, is generally considered safe; it’s best to skip irregularly shaped ice from questionable places, especially in the first days of your trip.
• Stomach upset in the first few days — a normal reaction to new gut bacteria; with severe symptoms, see a doctor right away rather than waiting it out.

Important: this is informational material, not medical advice. If you feel unwell or have a chronic condition, see a doctor — general advice from the internet does not replace individual diagnosis.

A full comparison of policy requirements and help choosing insurance is in the guide travel insurance for Thailand. A list of tropical diseases and basic prevention is in the article on main health risks in Thailand.

What to see on your first trip

If it’s your first time, it makes sense to build your itinerary around the “golden classics” — places people have been visiting for decades. No made-up rankings, just the essentials. 🌴

In Bangkok the essential trio:

• Grand Palace — the royal family’s residence and the country’s main architectural complex.
• Wat Arun — the Temple of Dawn on the bank of the Chao Phraya River, a recognizable postcard view.
• Chatuchak Weekend Market — the largest market in Southeast Asia, open on Saturdays and Sundays.

Opening hours and prices change — for details, check the list of top Bangkok attractions before your trip and in current listings on the official website of the Tourism Authority of Thailand.

In Phuket the itinerary is different — the island is about nature and beaches, not cultural monuments on a capital-city scale. For a basic list with our recommendations, see the article top 10 places in Phuket.

Pattaya — it’s more of a base for day trips: Bangkok is two hours away, and Nong Nooch Park and nearby islands are even closer. Specific routes are covered in regional guides, not in this overview.

The main itinerary tip for a first trip: don’t try to see all of Thailand in a week. Two or three places at a relaxed pace are better than ten at a gallop with six-hour daily drives.

What not to do on your first trip: common beginner mistakes

A short summary worth going through the day before your flight. Each point is a real story that keeps repeating among first-time travelers.

1. Filling your whole itinerary with one resort and then regretting that you haven’t seen anything else.
2. Trying to take in everything in one week and spending half your time on the road between Bangkok, Phuket, Koh Samui, and Chiang Mai.
3. Underestimating the climate: heat plus humidity is much harder than dry 35°C in Europe. And a separate issue — PM2.5 in the north in February–April.
4. Not getting insurance or buying a policy with a deductible, no motorbike coverage, and no dengue coverage.
5. Trying to pay with a Mir card and ending up without a working payment method.
6. Renting a motorbike without an IDP and without motorcycle riding experience.
7. Bringing a vape or e-cigarettes — importing them can bring up to 10 years in prison or a fine of five times their value.
8. Skipping TDAC — you submit the card online within 3 days before arrival; without it, you may be refused boarding at check-in.
9. Traveling without a return ticket — immigration officers can require one.
10. Buying an “exceptionally cheap tour” without checking insurance, connections, and hotel terms.
11. Carrying all your cash in one wallet — split it up: some in the hotel safe, some on you.
12. Ignoring the dress code at temples — you won’t be let in, and your tour schedule will fall apart.

The list looks long, but half of the items can be taken care of at home: insurance, passport, TDAC, IDP. The rest comes down to common sense once you’re there.
