1Bangkok
Base · 1–4 days
Thailand’s essential urban stop: river temples, Chinese-Thai food, serious hotels, markets and neighborhoods that reward three nights rather than a rushed layover. Traffic is punishing, so stay near BTS or MRT instead of trusting map distance.
2Chiang Mai
Base · 4–5 days
The strongest first introduction to the Lanna north: temples, northern food, craft culture and easy access to hills and national parks without Bangkok-level intensity. It needs enough time for an unplanned café or market afternoon, not just packaged day tours.
3Phuket & Phang Nga
Base · 7 days
Thailand’s easiest Andaman beach region, with direct flights, a deep hotel roster and boat access to Phang Nga Bay. Avoid Patong unless loud nightlife is the point; base yourself in Kata, Kamala, Bang Tao or quieter northern beaches.
4Krabi, Railay & Koh Lanta
Base · 7 days
The limestone-and-longtail-boat south: Railay for the dramatic setting and climbing, Krabi for access, Koh Lanta for a slower beach stay. Ao Nang is useful but not especially lovable; Phi Phi is best treated as a day trip or a deliberate party choice.
Koh Samui, Koh Phangan & Koh Tao
The Gulf-island alternative when the Andaman coast is a weather gamble: Samui is convenient and developed, Phangan has quiet beaches beyond the party zone, and Tao is for diving. Island hops and ferry timing make this a beach trip, not a quick add-on.
Khao Sok & Cheow Lan Lake
The worthwhile jungle counterweight to a beach-heavy itinerary, with limestone cliffs, rainforest lodges and floating raft houses on Cheow Lan Lake. Give it two nights; it is too far and transfer-heavy to treat as a casual Phuket day trip.
Ayutthaya
The most practical historic-capital stop from Bangkok, with temple ruins that work as a day trip or one night. Choose it when convenience matters more than having the ruins largely to yourself.
8Sukhothai
Thailand’s more spacious and atmospheric historic-capital experience, best explored slowly by bicycle in the cooler hours. It is the better ruins stop if you have time between Bangkok and Chiang Mai; do not cram it in alongside Ayutthaya on a short trip.
9Kanchanaburi
Base · 2 days
A strong two-night escape west of Bangkok for River Kwai history, raft-house stays and Erawan’s waterfalls. Look past the tacky bridge-area tourism toward the Thailand–Burma Railway and Hellfire Pass context.
10Chiang Rai
Base · 2 days
A quieter far-north base for the White Temple, Blue Temple, Black House, tea country and Golden Triangle context. It complements Chiang Mai rather than replacing it: two nights is usually enough unless you are driving deeper into the north.
Isan
Thailand’s broad northeast is for Lao-influenced food, Mekong towns and Khmer-era ruins rather than polished resort travel. Focus on one corridor—such as Udon Thani and Nong Khai, or Buriram and Phimai—and fly in rather than donating days to buses.
Sample routes
Food, temples and the Lanna north
8 daysBangkok (3 days) → Chiang Mai (5 days, including the Bangkok–Chiang Mai flight or overnight train)
The best first trip if beaches are not the priority. Bangkok gets proper city time rather than a token layover; Chiang Mai delivers northern food, temples and a hill-country day without adding another airport transfer.
Plan this routeBangkok and the limestone coast
10 daysBangkok (3 days) → Krabi, Railay & Koh Lanta (7 days, including the flight south and a weather-buffer day)
Choose this for dramatic scenery over a resort compound. Fly to Krabi, sleep on Railay for the cliffs and boats, then use Koh Lanta if you want the second half slower. Do not bolt on Chiang Mai: three destinations in ten days is an airport-heavy mistake.
Plan this routeClassic first Thailand circuit
14 daysBangkok (3 days) → Chiang Mai (4 days, including the flight from Bangkok) → Phuket & Phang Nga (7 days, including the Chiang Mai–south transfer)
This is the sensible three-part first visit: capital intensity, a genuinely different northern culture, then an easy-logistics Andaman finish. The long legs need flights; if Chiang Mai-to-Phuket is not direct on your dates, accept that the connection through Bangkok consumes most of a day.
Plan this routeDeeper Thailand: river history, far north and a real beach finish
20 daysBangkok (4 days) → Kanchanaburi (2 days) → Chiang Mai (4 days, including the return from Kanchanaburi and onward travel) → Chiang Rai (2 days) → Krabi, Railay & Koh Lanta (7 days, including the far-north-to-south flight connection) → Bangkok (1 day before departure)
For travelers who want more than the standard Bangkok–Chiang Mai–beach loop. Kanchanaburi adds River Kwai history and greenery; Chiang Rai earns its place as a short, quieter far-north contrast. The Chiang Rai-to-Krabi leg is a serious transfer, usually via Bangkok, so the long southern stay is non-negotiable.
