Two weeks is enough for a first trip that covers Thailand's three classic regions: three nights in Bangkok, four in Chiang Mai, and about six on one island coast. Pick the Andaman side (Krabi, Phi Phi, Lanta) from November to April, or the Gulf side (Samui, Phangan, Tao) when the Andaman coast is in its monsoon.
The mistake most first-timers make is trying to see everything: Bangkok, Chiang Mai, Pai, Chiang Rai, Phuket, Samui and Koh Tao in fourteen days. On a map Thailand looks compact. In practice each move between regions costs most of a day, and every extra stop means another morning of packing, checking out and waiting at a pier or an airport.
This page is about the route itself: the order of the stops, how you travel between them, how long each leg takes and which season suits which coast. Each stop gets a few lines and a link to the guide that covers it in depth. We have kept the plan to three bases, then shown how to shrink it to ten days or stretch it to three weeks.

Before you book: the season decides the island half
The north and Bangkok can be visited all year, with trade-offs. The islands cannot be swapped around so freely, because the two coasts get their heavy rain at different times. Decide on the coast first, then build the rest of the route around it.
The Thai Meteorological Department's 1991–2020 averages make the pattern clear. Phuket town gets about 24 mm of rain in February but more than 300 mm a month from August to October. Koh Samui, on the Gulf side, is the other way round: November averages 445 mm, while June to August stay between roughly 100 and 135 mm a month. January to April is the one period when both coasts are usually in good shape.
| When you travel | Island coast to pick | The north |
|---|---|---|
| November–December | Andaman (Krabi, Phi Phi, Lanta) | Cool, dry evenings in Chiang Mai |
| January–April | Either coast | Smoke haze from January, worst in March |
| May | Gulf (rains start on the Andaman side) | Hot, with the first storms |
| June–September | Gulf (Samui, Phangan, Tao) | Green and wet; August is Chiang Mai's wettest month |
| October | Late in the month, the Andaman side; avoid the Gulf from late October | Rain easing |
Our guides to Thailand's weather month by month and to the best time for the Thai islands go through each month and region in detail.
Autumn 2026: check flood warnings before you lock in dates. The UK Foreign Office updated its Thailand advice on 28 September 2026 with information on severe flooding, and several national parks have closed: Khao Yai indefinitely since 25 September, and Erawan and the main sites of Sai Yok since 27 September. If a stop on your plan is a park, check that it is open the week you travel.
Days 1–3: Bangkok, grouped by area
Land, get through immigration, and spend the first afternoon doing very little. Jet lag and heat make a temple on day one a poor idea. Which airport you land at matters for your first taxi or train ride, and our guide to Suvarnabhumi and Don Mueang explains the difference.
For the three days themselves, follow our plan for Bangkok in three days: the old town and the river first, markets and modern Bangkok second, Chinatown or a day trip third. We do not repeat it here. The only change for this route is to keep your bags packed on the evening of day three, because the next leg starts that night or early the next morning.
Bangkok to Chiang Mai: night train or flight
This is the first long leg, roughly 700 km north. You have two sensible options, and the choice is really about whether you want the journey to be part of the trip.
- The night train leaves Krung Thep Aphiwat Central Terminal in the evening and reaches Chiang Mai the next morning, roughly 11 to 13 hours later. It saves a night's hotel, and the last hours through the hills are pleasant in daylight. Long-distance trains no longer leave from the old Hua Lamphong station. Our guide to Thailand's night trains covers berths and booking; the special express sleepers to Chiang Mai open for sale 90 days ahead.
- A flight is just over an hour in the air, plus the trip to the airport and check-in. Thai AirAsia flies to Chiang Mai from both Bangkok airports since 1 October 2026, so check which airport is printed on your ticket.
If you take the train, board on the evening of day three: the berth is your third night, so book only two hotel nights in Bangkok, and you wake up in Chiang Mai on day four. If you fly, take a morning flight on day four and you still have the afternoon there.
Days 4–7: Chiang Mai as your northern base
Chiang Mai is the easiest base in the north: walkable old city, temples, night markets, cooking classes and mountains half an hour away. Four nights gives you two days in town and one or two days outside it. Our Chiang Mai guide covers the city and where to stay.
For a day out, Doi Suthep is the obvious first choice, and the old article on day trips from Chiang Mai lists the others, from Doi Inthanon to the sticky waterfalls. Pick one; doing two long day trips in four nights leaves no time for the city.
Pai and Chiang Rai do not fit comfortably into a 14-day trip with an island half. Each needs at least two nights to be worth the road. If the north matters more to you than the beach, take our northern Thailand itinerary by bus and cut the island half to four nights instead.
Chiang Mai in March is a smoke-season gamble. The Thai Meteorological Department's normals record haze on about 27 days in March at the Chiang Mai station, and the UK Foreign Office warns of seasonal smoke from field burning in the north. If you travel from February to April and have breathing problems, shorten the northern half.
Day 8: Chiang Mai to the islands by air
This is the leg that makes a two-week trip work. Going south overland from Chiang Mai means a day on the train back to Bangkok and then another night on a train or bus south. A flight does it in an afternoon.
For the Andaman version, look first at a direct flight from Chiang Mai to Krabi, a route Thai AirAsia has flown; check the current schedule, and if there is no direct flight that day, connect in Bangkok. For the Gulf version, the simplest route is to fly to Bangkok and connect to Koh Samui; Samui's airport is owned by Bangkok Airways, which runs most flights there, so compare that fare with flying to Surat Thani on the mainland and taking the joint bus-and-ferry ticket. Our guide to domestic flights in Thailand explains baggage rules on the low-cost airlines, which matter when you are carrying a fortnight's luggage.
Days 8–13, Andaman version: Krabi, Phi Phi and Koh Lanta
From November to April, base yourself first in Ao Nang or Railay for two nights, then move to one island for the rest. The Krabi guide compares Ao Nang, Railay and Krabi Town.
- Krabi to Phi Phi: Andaman Wave Master's ferry between Krabi's Klong Jilad pier and Tonsai on Phi Phi takes about two hours (operator timetable, October 2026). Other operators sail from other Krabi piers, so check which one your ticket names.
- Phi Phi or Koh Lanta for the last nights: Phi Phi is small and busy; Lanta is long, quieter and better for families. Both are on the boat network that runs between the islands from about 15 October to 30 April.
For more than two islands in a row, and for the speedboat legs, prices and the park fees, our Andaman island-hopping route has it all, from Phuket down to Koh Lipe. On this two-week plan you only use the first part of it.
Fly home from Krabi or Phuket. Thai AirAsia flies Krabi to both Bangkok airports, so again check the airport on the ticket, and leave a spare night on the mainland before an international departure if your last leg is a boat.
Days 8–13, Gulf version: Koh Samui and one more island
From June to September, or from January to April if you prefer the Gulf, take the islands in a line. Samui has the airport and the most choice of hotels; Phangan is quieter outside the party nights; Koh Tao is built around diving. With six nights, choose Samui plus one of the other two rather than all three.
Our Gulf island-hopping route explains the ferries between the three islands, the piers and the order that avoids backtracking. If you end on Koh Tao, the boat to Chumphon connects with trains and buses back to Bangkok.
The Gulf's own warning: from late October to December, crossings are rougher and smaller boats are cancelled more often. That is the season to choose the Andaman side instead.
Day 14: getting home without missing the flight
Plan the last day so that no boat, bus or domestic flight is the only thing between you and an international departure. Ferries are delayed by weather; low-cost flights are rescheduled. Our view: fly back to Bangkok the day before your flight home, or book the international flight from Phuket, Krabi or Samui itself if a direct route suits you.
Your last night in Bangkok can be near the airport or in town. If you land back at Don Mueang and fly out of Suvarnabhumi, allow for the transfer between them: the free shuttle bus is only for passengers connecting between flights on the same day with proof of an onward ticket.
The 10-day version: drop a region, not a day
Ten days is enough for two regions done properly, or three done in a hurry. We would choose two.
| Option | Nights | Best for |
|---|---|---|
| City and north | Bangkok 3, Chiang Mai 4, Pai or Chiang Rai 2 | Hot-season or rainy-season trips, culture first |
| City and beach | Bangkok 3, one island coast 6 | A first trip with a family or a short holiday |
| All three, fast | Bangkok 2, Chiang Mai 3, one island 4 | Travelers who accept a flight every few days |
In the fast version, fly every long leg and stay in one place on the islands. A ten-day trip that includes a night train and two island changes spends too much of its time in transit.
The 21-day version: slower, with a third region
Three weeks fits inside the 30-day visa exemption that most visitors receive (as of October 2026), though the rule has changed several times, so check our page on Thailand's visa exemption for your passport before you book. Use the extra week to slow down rather than to add more stops.
- Add a day trip or a night outside Bangkok. Ayutthaya, the old capital, is an easy train ride north; our guide to the train to Ayutthaya explains which station to use. Kanchanaburi and the Death Railway are about three hours west by train from Thonburi station, but Erawan Falls and Sai Yok were closed after flooding in late September 2026, so check their status first.
- Do the northern loop properly. Add Pai or Chiang Rai with two or three nights each. Greenbus coaches between Chiang Mai and Chiang Rai take about 3 hours 20 to 3 hours 45, and minivans to Pai leave Chiang Mai every hour.
- See both coasts from January to April. The overland link between the Gulf and the Andaman side runs through Surat Thani: Phantip Travel's minivans take about three hours from Surat Thani to Krabi (six departures a day, 290 baht, as listed for 2026).
The overnight train south saves a hotel night too. Train 85 leaves Krung Thep Aphiwat at 19:50 and reaches Surat Thani at 06:23, according to the October 2026 timetable published by seat61; from there it is a bus and ferry to Samui or a minivan to Krabi. SRT's own site was unreachable when we checked, so confirm the times in the D-Ticket app.
What two weeks costs in time and money
A realistic rhythm is one major move every three or four days. In the 14-day plan that means three long legs (Bangkok–Chiang Mai, Chiang Mai–islands, islands–home) and one or two short boat rides. Anything more starts to feel like a commute.
Costs depend mostly on your rooms and on how you travel between regions; island boats and national park fees add up faster than food. Our guide to what a day in Thailand costs builds budgets for three travel styles. Fill in the free Thailand Digital Arrival Card before you fly, only on the official site, and buy travel insurance that covers boats and any scooter riding you plan.
Frequently asked questions
Is two weeks enough for Thailand?
Two weeks is enough for Bangkok, Chiang Mai and one island coast at a comfortable pace. It is not enough for both island coasts plus Pai and Chiang Rai without spending a large part of the trip on the road. Choose three bases and fly the long legs.
Should I take the night train or fly from Bangkok to Chiang Mai?
Take the night train if you enjoy rail travel and want to save a hotel night; it takes roughly 11 to 13 hours. Fly if your time is short: the flight is just over an hour in the air. Thai AirAsia uses both Bangkok airports, so check which one is on your ticket.
Which islands should I choose for a two-week trip?
From November to April, choose the Andaman side: Krabi with Phi Phi or Koh Lanta. From June to September, choose the Gulf: Koh Samui with Koh Phangan or Koh Tao. From January to April both coasts are usually dry, so decide by the kind of island you want.
Can I visit Thailand for three weeks without a visa?
For most Western and many Asian passports, yes: the visa exemption is 30 days as of October 2026, after the 60-day exemption ended on 15 September 2026. Some nationalities have other rules under bilateral agreements, so check the official list for your passport before you book.
What is the best order for a first trip to Thailand?
Bangkok first, then the north, then the islands. Starting in the capital lets you get over jet lag with good transport around you, the north is cooler and more active, and ending on a beach gives you rest before the flight home.
