The short version
Thailand is one of the easiest countries in the world to travel for the first time. The infrastructure works, English is widely spoken in tourist areas, the food is safe and superb, and almost nothing will go badly wrong. What follows is the handful of things genuinely worth knowing before you land, in the order you will need them.
1. Entry
Most nationalities get a visa exemption on arrival for a set number of days, and everyone now needs to complete the digital arrival card before entering. Check your own passport’s entitlement rather than assuming — the rules changed in 2025 and again in 2026.
- The Thailand Digital Arrival Card (TDAC) — required, free, do it before you fly.
- The 60-day visa exemption — who gets it and what it allows.
- The visa tool — pick your passport, get your answer.
2. Money and connectivity
Get a SIM or eSIM at the airport or before you fly, and take cash out of an ATM rather than changing money at the terminal. Everything else — maps, ride-hailing, booking apps — assumes you are online.
- SIM cards and eSIMs — sorted in ten minutes.
- What to pack — and what to buy at the 7-Eleven instead.
- What things cost — daily budgets and the ATM fee.
- ATMs, cards and the ฿220 fee — how to pay less to reach your own money.
- What a day costs — three itemised budgets from real prices.
- The price index — 58 real prices, fair vs tourist quote.
3. When you are going, and therefore where
The month decides the coast. The Andaman is at its best November to April; the Gulf islands February to September. Getting this backwards is the most common first-trip mistake.
- Best time to visit — month by month.
- The province matcher — four questions, all 77 provinces.
- Things to do in Bangkok — worth it vs skip it, with prices, for the city you will land in.
4. Getting around
Domestic flights are cheap and save days. Trains are slow and lovely. Buses go everywhere. Use Grab in cities rather than negotiating with tuk-tuks.
- Getting around Thailand — every option, costed.
- BKK or DMK? — Bangkok’s two airports and the cheapest way into town.
- Bangkok to Chiang Mai — the four ways compared.
5. Eating
Eat the street food. High turnover is what matters, not appearances — a stall with a queue is cooking fresh. The one word worth learning is jay (เจ) if you are vegetarian or vegan, because fish sauce is in almost everything by default.
- The Thai food guide — dishes, prices, and how to order spice.
6. Behaving well
Cover shoulders and knees at temples, keep your temper, and do not joke about the monarchy. That covers most of it.
- Temple etiquette — before your first wat.
- Thai culture — the fuller picture.
7. Safety
Thailand is safe for visitors by most measures. The real risks are road accidents — overwhelmingly scooters — and losing money to scams rather than to crime.
- Is Thailand safe? — a straight answer.
- The 12 scams still running — what each one costs and the sentence that ends it.
- The 2026 travel rules — what changed this year.
- Vaping — still illegal, and still catching people out.

First trip to Thailand: your questions, answered
Do I need a visa for Thailand?
Most nationalities do not for a short holiday — a visa exemption is granted on arrival, currently up to 60 days for many passports. Everyone must complete the digital arrival card before entry. Check your specific passport, as the rules have changed twice recently.
Is Thailand safe for first-time travellers?
Yes, by most measures safer than many European destinations for violent crime. The genuine risks are road accidents, particularly on rented scooters, and opportunistic scams around transport and tours rather than anything dangerous.
Can you drink the water in Thailand?
Not from the tap. Bottled and filtered water is cheap and everywhere. Ice from commercial machines — the cylindrical kind with a hole through the middle — is made from treated water and is fine.
How much should I budget for a first trip to Thailand?
Around ฿2,500–4,500 per person per day covers a comfortable trip with decent hotels and a mix of street food and restaurants. Backpacking works from about ฿1,200 a day. International flights are on top.
