Thailand is one of the easiest countries in Asia to fall for and one of the easiest to over-plan. You could land with nothing booked and still have a wonderful trip, but a handful of decisions made before you fly, when to go, how to move between regions, where to base yourself, will turn a good first visit into a great one. This is the guide we wish someone had handed us the first time, wherever you are flying from.
When to go
Thailand has three broad seasons, and they matter more here than the calendar suggests. The cool, dry season runs roughly November to February and is the sweet spot: warm days, low humidity, and blue skies almost everywhere. This is peak season for good reason, so book ahead. March to May is hot, genuinely hot, with April the peak and the wild water fights of Songkran mid-month. The green season, roughly June to October, brings the monsoon, usually as short heavy downpours rather than all-day rain, along with lower prices and lush landscapes.
One quirk to remember: the two island coasts run on opposite clocks. The Andaman side near Phuket and Krabi is best roughly November to April, while the Gulf side near Koh Samui often shines January to August. More on that in our best time to visit guide.
The visa, in one paragraph
US, UK, Irish, EU, Canadian, Australian, New Zealand and South African visitors all currently receive a visa exemption on arrival, worth up to 60 days at the time of writing. A reduction to 30 days has been approved by the Thai cabinet and will apply once it is formally published, so the stamp you get depends on when you arrive. Check the current rule for your passport shortly before you travel rather than trusting an old blog, and do not build a two-month trip around the longer allowance. You also need to fill in the free TDAC arrival card online in the three days before you land. Have proof of onward travel handy, keep at least six months of passport validity, and you are set.
Where to base yourself
Thailand is really three trips in one, and picking your regions beats trying to see everything. Bangkok is the electric, temple-and-street-food capital and the country’s main gateway, worth two or three nights at least. Chiang Mai and the north offer cooler air, old-city temples, mountains and ethical elephant experiences. The southern islands and beaches are where you slow down, whether that is the buzzy Andaman coast or the calmer Gulf.
A classic first two weeks looks like a few nights in Bangkok, a few in Chiang Mai, then a beach finale on an island. Ending on the beach rather than starting there is deliberate: the cities are more rewarding with energy, and nobody has ever regretted finishing a trip doing nothing.
Getting around
Distances are long, but the transport is cheap and easy. Domestic flights are the time-saver for hops like Bangkok to Chiang Mai or the south, often startlingly affordable if booked ahead. Trains and buses are comfortable for slower, scenic travel, and ferries connect the islands. In cities, use the Grab app for taxis and the BTS Skytrain and MRT in Bangkok, and enjoy a short tuk-tuk ride once for the fun of it, agreeing the fare first.
Book the big days out before you landSanctuary mornings and island boat trips sell out fast in high seasonWhat to book ahead, and what to leave loose
Book your first two nights so you land somewhere sorted, your internal flights while they are cheap, your headline experiences with limited spots, and an eSIM so you have data the moment you switch on your phone. Almost everything else, restaurants, massages, extra tours, local transport, is cheap and abundant on the ground, so resist the urge to lock down every hour. Thailand rewards a loose plan.
Temple etiquette and small courtesies
Thailand is deeply Buddhist, and its temples are living places of worship. Cover your shoulders and knees, remove your shoes where indicated, and never point your feet at a Buddha image or turn your back to one for a photo. Treat all images of the King and the royal family with respect, this is taken very seriously. Keep your voice down, keep your temper cooler still, and you will be welcomed warmly everywhere.
Money, water and staying well
The currency is the Thai baht (THB). Rates move, so check a converter shortly before you go rather than relying on a figure in an old article. Cards work at hotels, malls and bigger restaurants, but carry cash for street food, markets and tuk-tuks. Use ATMs attached to real banks and expect a small withdrawal fee. Do not drink the tap water: stick to sealed bottled or filtered water, which is cheap and everywhere. Pack sunscreen, mosquito repellent and any regular medicines, and take out travel insurance, especially if you plan to rent a scooter, as many standard policies exclude two wheels. If you intend to ride or drive at all, bring an International Driving Permit from home along with your own licence, because Thai law requires it and your insurer will ask.
What a first trip actually looks like
Route matters more than any other decision on a first visit, because Thailand is long and its highlights sit at opposite ends of it. These three shapes cover almost everyone.
| Length | The shape | What to skip |
|---|---|---|
| One week | Bangkok plus one island, or Bangkok plus the north | Trying to fit all three regions |
| Ten days | Bangkok, the north, one island, flying between them | A second island |
| Two weeks | The same three, unhurried, with a slow island finish | Extra towns you read about once |
The constant is three bases, not six. Every move costs the better part of a day once you count checkout, transfer, waiting and settling in, so an itinerary with five stops in twelve days is mostly an itinerary of departures. Fly the long legs, then travel slowly inside each region where minivans, ferries and songthaews are cheap and frequent.
What it costs, honestly
Thailand is genuinely good value, and the range between budgets is wider than in most countries, which is why the numbers people quote vary so much.
At the budget end, street food, guesthouses, fans instead of air conditioning and public transport make for a very cheap day. In the middle, a comfortable hotel, air conditioning, a mix of local and restaurant meals and the occasional taxi still costs a fraction of the equivalent in Europe or North America. At the top end, Thailand does luxury properly and charges accordingly, though even then it usually undercuts comparable places elsewhere.
Three things break budgets more than daily spending: islands, where everything has to arrive by boat, transfers, where a chain of airport, ferry and taxi can outprice the flight, and peak season, where the same room can cost several times its low-season rate. Prices move with the season and the exchange rate, so treat any figure you read, including ours, as a range rather than a quote.
The things first-timers get wrong
Almost every first-trip regret comes from the same short list.
Overpacking the itinerary is the big one, and the fix is above. Underestimating the heat is the next: the local rhythm of early mornings, an indoor afternoon and a second life after sunset exists for a reason, and fighting it turns sightseeing into endurance. Renting a scooter without the licence or the cover is the one that turns expensive, since a car-only licence does not permit a motorcycle and many policies exclude two wheels outright.
Then the small stuff. Turning up at a temple in a vest and shorts means paying for a cover-up at the gate or being turned away. Losing your temper in a disagreement makes everything worse here, where staying calm is the expected way to resolve things. And accepting an unusually cheap ride from someone who approaches you usually means a detour to a shop that is paying them.
Health, insurance and peace of mind
Thailand has excellent private hospitals in the cities and on the main islands, and good pharmacies almost everywhere, which handle the majority of travel ailments without drama. What you need is a way to pay for the serious end of that scale.
Travel insurance is not optional here, and the reason is specific rather than general: scooter accidents are the most common serious injury among visitors, and standard policies frequently exclude motorbikes, or cover them only if you hold the correct licence and wear a helmet. Diving, and any repatriation, sit in the same category of things worth checking rather than assuming. Our guide to travel insurance for Thailand sets out what to look for before you buy.
Everyday health is straightforward. Drink bottled or filtered water rather than from the tap, use repellent in the evenings, take sun protection seriously, and speak to a travel clinic well ahead about any vaccinations or malaria advice for the specific areas you plan to visit, since that guidance is personal and changes.
Still deciding between Thailand and somewhere else?
Plenty of first trips to Southeast Asia come down to a straight choice, most often with Vietnam, and the honest answer is that they suit different travellers rather than one being better.
Thailand is the easier country: better tourist infrastructure, shorter internal flights, more English spoken in the places visitors go, and beaches that are genuinely world class. Vietnam covers more ground culturally and historically, costs a little less in most categories, and asks slightly more of you in return. Our comparison of Thailand and Vietnam weighs both across cost, food, beaches, transport and how much a two-week trip actually sees.
The short version
Go in the cool season if you can, split your trip between Bangkok, the north and an island rather than cramming, book internal flights and headline days early, sort an eSIM before you land, respect the temples and the royal family, and carry cash for the small stuff. That split is exactly how our 10-day Thailand itinerary is built, with Bangkok, Chiang Mai and a beach finale planned out day by day. Do that, and your first Thailand trip will feel less like a logistics puzzle and more like the start of a long friendship with the country.
