Thailand travel guide

How to use this guide

Thailand rewards a plan that starts with the big, immovable decisions and lets the small ones fall into place afterwards. The big ones are the season, the coast and the route shape; the small ones are the hotels, the day plans and the street-food stops. Get the order right and the trip almost assembles itself. Get it wrong — book the beach before you've checked the coast's season, or stack six destinations into ten days — and no amount of good hotels can save it.

So this guide is built as a spine, not a list. It moves from the country-wide decisions at the top (where, when, how long) down through the route shapes and the regional silos to the practical layer that smooths the trip. You don't need to read all of it. Start at the top, make the two or three decisions that matter, and follow the links down to the pages that go deep on each one.

A word on what Thailand actually is, because it shapes everything: it isn't one destination but several, stitched together by cheap flights and a long peninsula. There's Bangkok and the central plains; the cool northern highlands around Chiang Mai; the limestone Andaman coast in the west; the Gulf islands in the east, on a different season entirely; and a heritage heartland of old capitals and national parks in between. A good trip picks two or three of these, not all of them.

Where to go in Thailand

Compare the regions by trip style and season — the decision that shapes everything else.

First time in Thailand

The beginner decisions — how many stops, what to book, and the mistakes to avoid.

Decide the season and the coast first

If there's one decision that makes or breaks a Thailand beach trip, it's the coast — and it's tied to the calendar. The Andaman coast in the west (Phuket, Krabi, Phi Phi, Koh Lanta, Khao Lak) usually has its most settled weather from roughly November to April, with wetter and rougher conditions during much of the southwest monsoon. The Gulf islands in the east (Koh Samui, Koh Phangan, Koh Tao) often receive their heaviest rain later in the year, especially around October to December. These are tendencies rather than guarantees, so check the live marine forecast before boat travel.

That single fact settles more of your itinerary than any list of attractions. Pick the coast that matches your dates and the right islands almost choose themselves; ignore it and you risk booking a longtail-boat beach in the one month the seas are roughest. Inland is simpler: the cool, dry stretch from November to February is the broad sweet spot countrywide, while the northern highlands carry one extra caveat — a haze season from roughly February to April when agricultural burning can dull the air around Chiang Mai.

Seasonality is a planning guide, not a forecast — monsoon conditions vary; rain may be brief or prolonged, and current warnings matter. But it does decide sea conditions and ferry reliability, so settle the coast and the month before you fall for a specific resort.

Choose a route shape, then the destinations

The second decision is shape. Thailand is large and cheap to fly around, which tempts people into six stops in ten days — and every move has a hidden cost: a transfer to the airport or pier, a flight or ferry, a transfer at the other end, and the half-day of momentum lost to all of it. Two regions done well almost always beat five done in a rush.

A useful rule of thumb: in ten days, pair one culture base with one beach region. In two weeks you can add a third region. Order should follow the gateways available for your dates: Bangkok is the largest hub, but direct international flights to Phuket, Chiang Mai, Krabi, Samui and other regional airports can make an open-jaw or beach-first route more efficient.

Once you know the shape, pick the destinations to fill it from the regional silos: Bangkok and the central plains, the North around Chiang Mai, the Andaman coast, the Gulf islands, the heritage heartland and the national parks. Each has its own hub on this site that goes deep on what to do, where to stay and how to get there.

Thailand itineraries

Ready-made routes for 7, 10, 14 or 21 days — first-time, island-hopping, North, South and more.

A worked example — Bangkok, the North and beach time, without overpacking transfers.

The pieces that fill the plan — islands, hotels, food, transport

With the season, the coast and the shape settled, the rest is detail — and detail is where this guide goes deep. For beaches, the islands page compares the Andaman and the Gulf by season, beaches, diving and mood, and names the best area to base on each. For accommodation, the country splits into two clean jobs: choosing the right region or base for a first trip, then drilling into specific properties by style — luxury, beach, family, boutique or budget.

Getting between the pieces is its own skill in Thailand. Domestic flights are cheap and save the long days; the night train south is a Thailand experience in itself; ferries and speedboats connect the islands but run on the season and the weather. The transport hub explains how the modes fit together, and the route pages cover specific journeys — Bangkok to Chiang Mai, Bangkok to Phuket, the ferries to the Gulf — in detail.

And then there's the food, which for many travellers is the point. Thailand's street stalls, night markets, food cities and cooking classes are a thread you can pull through the whole trip. The food pillar covers what to eat and where, from a Bangkok hawker stall to a northern khao soi.

The practical layer — visa, money, getting around safely

The last layer is admin. Most non-Thai nationals entering through immigration submit the TDAC, while published exceptions include Thai nationals, airside transit without immigration, crew and Border Pass users. Visa and exemption rules depend on nationality and can change, so verify both through official sources close to travel.

On the ground, a few decisions repeat: how to get from the airport, whether to use a metered taxi or a ride-hailing app, whether to rent a scooter (and the very real risks if you do), and how to avoid the handful of common tourist scams. None of it is hard, but a little reading beforehand saves the awkward first-day fumbling. From here, follow the spine down — pick where and when, choose a shape, then let the silos and the practical pages fill in the rest.
