For a first trip, plan 10–14 days in Thailand. That covers Bangkok, the north around Chiang Mai and one island region without rushing. 7 days is enough for Bangkok plus one beach area, while 3 weeks lets you add a second island group or the far north.
Thailand is bigger than it looks on the map: Bangkok to Phuket is over 800 km, and Chiang Mai sits 700 km north of the capital. How many days you need depends on how many regions you want to combine. Below is a quick guide by trip length, four sample routes, advice per type of traveller and what each trip length costs.

Open the trip planner →| Trip length | Days | What you can realistically see |
|---|---|---|
| Stopover | 3–4 | Bangkok only: the Grand Palace, Wat Pho, the river, street food and a rooftop bar — or a quick beach break in Hua Hin or Pattaya. |
| One week | 7 | Two bases: Bangkok plus one beach area (Krabi, Phuket or Koh Samui), or Bangkok plus Chiang Mai. |
| Ideal first trip | 10–14 | The classic trio: Bangkok, Chiang Mai (with Ayutthaya or Pai as an add-on) and one island region. |
| Extended | 21+ | Add a second island group (Andaman and Gulf), Kanchanaburi, Sukhothai or the far north around Chiang Rai. |
A week is enough for a great first taste, as long as you limit yourself to two bases. Spend three nights in Bangkok for the temples, markets and food, then fly one hour south to Krabi, Phuket or Koh Samui for four beach nights. If you prefer culture and mountains to beaches, swap the island for Chiang Mai. Trying to squeeze in the north and an island in seven days means losing two of them to transit.
Ten to fourteen days lets you see Thailand's three very different faces — the capital, the northern mountains and the tropical islands — with one domestic flight between each. A typical split is 3 nights in Bangkok, 3–4 nights in Chiang Mai and 4–6 nights on the coast. Domestic flights (about 1–1.5 hours and often under €50 when booked ahead) keep the transfers short, so you only lose half a day each time you move.
With 21 days you can slow down and add depth. Popular add-ons are Pai or Chiang Rai in the north, Kanchanaburi for the River Kwai and Erawan Falls, the old capitals of Ayutthaya and Sukhothai, or a second island group: combine the Andaman coast (Krabi, Phi Phi, Lanta) with the Gulf islands (Samui, Phangan, Tao). Three weeks also suits divers who want to do a course on Koh Tao.
Four routes that follow a logical flow and keep travel days to a minimum. All start in Bangkok; the longer ones use a domestic flight or the overnight sleeper train between regions.
Plan 10–14 days and the classic Bangkok – Chiang Mai – island route. It is the best mix of culture, food and beach for a debut trip.
Go for 14 days with fewer moves: Bangkok, then one calm beach base such as Koh Lanta, Kata (Phuket) or Hua Hin, where the sea is gentle and transfers are short.
12–16 days lets you pair a boutique stay in Chiang Mai with a villa on Koh Samui, Koh Yao Noi or Railay — plenty of spa, sunset and slow mornings.
Think 3–4 weeks: the north loop via Pai, the Gulf islands (including the Full Moon Party on Koh Phangan) and a dive course on Koh Tao.
Add 4–5 days on Koh Tao for an Open Water course, or plan a liveaboard to the Similan Islands from Khao Lak (mid-October to mid-May).
Rough per-person costs excluding international flights, sharing a double room, based on mid-2020s prices for accommodation, food, domestic transport and activities.
| Trip length | Budget | Mid-range | Luxury |
|---|---|---|---|
| 7 days | €250–€350 | €550–€850 | €1,700+ |
| 10 days | €350–€500 | €800–€1,200 | €2,400+ |
| 14 days | €500–€700 | €1,100–€1,700 | €3,300+ |
| 21 days | €700–€1,000 | €1,600–€2,500 | €4,800+ |
The islands (especially Phi Phi, Samui and Phuket) cost more than Bangkok or the north; high season (December–February) pushes hotel prices up by 20–40%. See our Thailand trip cost guide for a full breakdown.
Plan 10 to 14 days for a first trip. That is enough for Bangkok, Chiang Mai and one island region with one domestic flight between each. One week works for Bangkok plus one beach area; three weeks lets you add a second island group or the far north.
Seven days is enough for a first taste if you stick to two bases, for example three nights in Bangkok and four nights in Krabi, Phuket or Koh Samui. Adding Chiang Mai as well is possible but means spending two days in transit.
Yes. Two weeks is the ideal length for a first visit: Bangkok, Chiang Mai (or Pai) and four to six nights on the islands, at a relaxed pace.
Two to three full days is enough to see the Grand Palace, Wat Pho, Wat Arun, the markets and a rooftop bar, with an extra day for a trip to Ayutthaya or the floating markets.
If you have 10 days or more, do both: the north for temples, mountains and culture, the islands for beaches. With only a week, choose one based on season and interests.
Excluding international flights, count on roughly 500 to 700 euros per person on a budget, 1,100 to 1,700 euros mid-range and 3,300 euros or more for luxury.
