One week in Thailand forces one honest decision up front: you cannot do the northern mountains and the southern islands both well in seven days. The distances are too big and every region change costs you the better part of a travel day. So the trip that works is Bangkok plus one region, done properly, with a single short internal flight linking them. This guide gives you three complete 7-day routes built exactly that way, with day-by-day tables, the flight logic behind each, jet-lag advice for day one, and the honest call on what to cut when the plan gets greedy.
Prices are in Thai baht with US dollars in parentheses at ฿33 = US$1 (July 2026), given as ranges because fares and ferry prices move with season and demand. If you have longer than a week, our fuller Thailand itinerary planner and trip planning guide cover more elaborate loops, and you can browse live Thailand events for what is on while you are here.
Can you see all of Thailand in one week?
No, and pretending otherwise is the fastest way to waste your trip. Thailand runs roughly 1,600 km north to south; Chiang Mai in the north and the southern islands are about a two-hour flight apart, and each region transfer burns most of a day in transfers, check-in and flights. In seven days you have time for Bangkok plus one other region, not both the mountains and the beaches. Choose your lane first, then everything else falls into place.
Which one-week Thailand route is right for you?
Pick the row that matches what you actually want from the week. All three keep Bangkok as the anchor and add one region via a single short flight.
| Route | Best for | The one flight | You get | You skip |
|---|---|---|---|---|
| A. Bangkok + Chiang Mai | Culture, temples, food, the north | BKK to Chiang Mai (CNX), ~1h 20m | Grand Palace, night markets, Lanna temples, cooler hills, elephant-sanctuary day trips | Beaches entirely |
| B. Bangkok + one island | A proper beach half, minimal moves | BKK to Samui (USM) or Phuket (HKT), ~1h 10m to 1h 20m | Two nights of city, four of one island, swimming and slow days | The north; a second island |
| C. Bangkok + Krabi / Andaman | Beaches plus limestone scenery | BKK to Krabi (KBV), ~1h 20m | Railay cliffs, Phi Phi day trip, longtail boats, Ao Nang beaches | The north; the Gulf islands |
Flight times are typical scheduled durations; domestic Bangkok hops run roughly ฿1,000-3,600 (US$30-110) one-way as of July 2026 depending on route, airline and booking lead time. Confirm current fares when you book.
Route A: Bangkok + Chiang Mai (the classic)
This is the default first-timer route, and for good reason: it pairs the frenetic capital with the calmer cultural heart of the north, no beach logistics required. Two or three nights in Bangkok, then a short flight up to Chiang Mai for temples, markets, food and a mountain day trip.
| Day | Base | Plan |
|---|---|---|
| 1 | Bangkok | Land, check in, stay light: a riverside stroll, a casual street-food dinner, early night to beat jet lag |
| 2 | Bangkok | Grand Palace and Wat Pho early, Wat Arun across the river, then a night market |
| 3 | Bangkok | Chinatown (Yaowarat) food crawl or a neighbourhood like Ari, evening flight or next-morning flight to Chiang Mai |
| 4 | Chiang Mai | Old-city temples (Wat Chedi Luang, Wat Phra Singh), Sunday or night bazaar |
| 5 | Chiang Mai | Doi Suthep temple and a mountain viewpoint, afternoon Thai cooking class |
| 6 | Chiang Mai | Ethical elephant-sanctuary day trip or Doi Inthanon national park |
| 7 | Chiang Mai | Slow morning, café and market, fly back to Bangkok for your onward connection |
The flight from Bangkok’s Suvarnabhumi (BKK) to Chiang Mai (CNX) takes about 1h 20m and typically costs ฿1,000-3,600 (US$30-110) one-way as of July 2026. For the city half, our detailed Bangkok 3-day itinerary and Chiang Mai 5-day itinerary go deeper than the rows above; trim the Chiang Mai plan to the four days you have here.
Route B: Bangkok + one island (done right)
Choose this when you want a real beach half without island-hopping stress. The trick is one island, not three. Two nights in Bangkok, then fly straight to a single island and stay put, so your beach days are actually spent on the beach rather than on boats.
| Day | Base | Plan |
|---|---|---|
| 1 | Bangkok | Land, easy first day, river and street food, early night |
| 2 | Bangkok | Grand Palace, Wat Pho, Wat Arun, evening market; fly out next morning |
| 3 | Island | Morning flight to Koh Samui (USM) or Phuket (HKT), afternoon on the beach |
| 4 | Island | Beach and pool day, sunset dinner, slow pace |
| 5 | Island | One boat day trip (Angthong marine park from Samui, or Phi Phi / James Bond area from Phuket) |
| 6 | Island | Free day: viewpoint, spa, kayaking or just the beach |
| 7 | Island | Morning swim, fly back to Bangkok for your onward connection |
Koh Samui has the simplest logistics because Bangkok Airways flies direct from BKK to Samui (USM) in about 65 to 75 minutes, though it is the priciest hop at roughly ฿2,600-5,000 (US$80-150) one-way as of July 2026. A cheaper alternative is a budget flight from Don Mueang (DMK) to Surat Thani for about ฿1,300-2,600 (US$40-80) plus a Lomprayah ferry combo, which adds a few hours but cuts the cost. Phuket (HKT) is served by many airlines from both Bangkok airports for roughly ฿1,100-3,300 (US$34-100) one-way, making it the easier-on-the-wallet island for a fly-in, fly-out week. For choosing between them, see our best islands in Thailand comparison.
Route C: Bangkok + Krabi and the Andaman coast
Pick this for beaches plus the dramatic limestone-karst scenery Thailand is famous for. Krabi is the gateway to Railay, Ao Nang and Phi Phi, and it packs a lot of variety into a short stay. Two nights in Bangkok, then fly to Krabi and base yourself near Ao Nang or on the Railay peninsula.
| Day | Base | Plan |
|---|---|---|
| 1 | Bangkok | Land, light first day, street food and an early night |
| 2 | Bangkok | Temples and a market, fly to Krabi next morning |
| 3 | Krabi | Morning flight to Krabi (KBV), transfer to Ao Nang or Railay, beach afternoon |
| 4 | Krabi | Railay Beach: rock climbing, Phra Nang cave beach, longtail hopping |
| 5 | Krabi | Phi Phi Islands day trip by speedboat or ferry |
| 6 | Krabi | Four Islands longtail tour or Hong Islands, or a slow beach day |
| 7 | Krabi | Morning swim, fly back to Bangkok for your onward connection |
The flight from Bangkok to Krabi (KBV) runs about 1h 20m and typically costs ฿1,150-3,300 (US$35-100) one-way as of July 2026. Krabi to Phi Phi is a 1 to 1.5-hour high-speed ferry crossing, and Railay is reachable only by longtail boat (about 10 to 15 minutes from Ao Nang), which is part of its charm. Note the seasons: the Andaman coast is at its best roughly November to April, while the monsoon can make the sea rough and some day trips patchy from around May to October, so weigh that against the Gulf-side timing if you are torn between Route B on Samui and Route C.
How should you handle day one and jet lag?
Keep your first day in Bangkok deliberately easy, and do not connect straight onto a second flight the day you land. Most long-haul arrivals reach Bangkok tired and time-shifted, and cramming the Grand Palace or an onward domestic flight into that first groggy day is how people burn out early. Arrive, check in, take a gentle riverside walk, eat some street food, and get an early night. Save the temples and the onward flight for day two or three when you are rested. This is why every route above front-loads a light Bangkok day before the internal flight, not after.
What should you cut first when the plan is too tight?
Cut the extra destination, not the rest days. The single most common one-week mistake is trying to bolt a third place onto a route that only has room for two, so you end up with a day and a half everywhere and your week dissolving into transfers. If your draft plan has Bangkok, Chiang Mai and an island, drop one region entirely rather than shaving a day off each. Two places done well beats four places half-seen every time. The next thing to cut, if you are still overloaded, is the most logistics-heavy day trip, not a slow day; the slow days are what make a trip feel like a holiday rather than a checklist.
Should you fly or take the bus or train between stops?
Fly for the one long hop. A domestic flight from Bangkok to Chiang Mai, Phuket or Krabi takes roughly 1 to 1.5 hours and costs around ฿1,000-3,600 (US$30-110) one-way as of July 2026, versus 9 to 12 hours or more by overnight bus or train. On a seven-day trip that flight buys back a whole day for a modest price, which is the best value on the entire itinerary. The scenic overnight train to Chiang Mai is a lovely experience, but it belongs on a longer trip where losing a travel day does not cost you a third of your beach or temple time. One practical catch: Bangkok has two airports, Suvarnabhumi (BKK) for full-service carriers and Don Mueang (DMK) for most budget flights, so check which one your onward flight departs from before booking your hotel and airport transfer.
