ThaiTripPlanner is a free, browser-based tool that helps you plan a trip to Thailand — building a personalized, day-by-day itinerary of 3 to 60 days from 40 hand-picked destinations, complete with routing, activity suggestions, accommodation styles and per-person cost estimates in a live, editable timeline.
Why we built it
Planning Thailand is deceptively hard: four very different regions, two monsoon seasons, dozens of islands, and a hundred blog posts that all contradict each other. Most trips go sideways not because of one big mistake but because of a poorly sequenced route — backtracking across the country, missing ferry connections, or cramming ten stops into a week. We wanted a tool that reads your travel style and gives you an honest, well-sequenced plan up front — friendly, practical and judgment-free — so the only surprises on your trip are the good kind.
How it works
You answer a short series of questions — around 20, covering your pace, budget, companions, beach-versus-mountain leanings and bucket-list wishes. The planner scores every answer against each of our 40 destinations, selects the best matches, and sequences them from your arrival hub (Bangkok or Phuket) to minimize backtracking. You get a mapped, costed, drag-to-reorder itinerary you can export, save or share. Everything runs in your browser; nothing you enter is sent to us.
About the numbers
Default cost figures are drawn from general research compiled in mid-2026 and are intended as planning ballparks, not quotations. Prices in Thailand shift with season, location, demand and exchange rates, and visa and entry rules change frequently — so always confirm current costs and requirements with official sources before you book. See our Terms & Disclaimer for the full picture.
Who's behind it
The Service is operated by Genext Information Systems, an independent web project run by a small team based in Thailand. ThaiTripPlanner started as a spreadsheet passed between expat friends who'd spent years exploring every corner of the Kingdom. It is part of a small family of free Thailand tools that also includes ThaiVisaFinder (long-stay visa comparison) and Uncle Pong's Thailand Holiday Estimator (trip cost calculator). "Uncle Pong" — the cheery fellow pictured here — is a fictional, good-natured host persona created to make planning a bit more fun. We are independent and not affiliated with any government body, airline, hotel or venue.

Start with the route, then add the details
A useful Thailand itinerary starts with the places you can realistically connect. Use the planner to sketch the length of your trip, then read the destination guides before deciding how many nights to spend in each stop. A name on a map is only the beginning: the important questions are what you want to do there, how you will get there, and whether the transfer leaves enough time to enjoy it. You can compare a city break, a northern route and an island stay without treating every suggested stop as a booking commitment.
Leave some space between the things you most want to do. An arrival day, a ferry connection and an evening festival all take time that a simple list of attractions can hide. If a route looks crowded, removing a stop can make the remaining days more useful. The planner is a starting point for these decisions; the destination pages add the context you need to turn the outline into your own trip.
Use the guides and news together
Destination guides answer the longer-lasting questions: what a place feels like, which sights belong together, and how it fits into a wider route. News articles cover developments with a date attached, such as an announced festival programme or a transport change. Read both when a particular event is the reason for your visit. An older guide may still explain the neighbourhood well while a newer article carries a more specific announcement. Publication dates and links to the original sources help you judge what the information applies to.
The festival calendar and Festival Finder offer another way into the site. Search around your travel dates, open the individual festival guide, and compare the event location with your planned overnight stops. A festival listed for a province may involve a particular town or venue rather than the whole region. Check the details of the event you intend to attend, including whether it is a public celebration or a separately ticketed programme. Build the route around the experience you want rather than a photograph alone.
Read photographs as context
The photo gallery gives you a visual introduction to places across the country. Use it to discover a landscape, town or neighbourhood you would like to investigate, then follow through to the written guides. A photograph captures a particular viewpoint and moment; it cannot tell you what a transfer will take, how busy a street will be on your dates, or whether a seasonal activity will operate. The written information and the original photographer's credit belong alongside the image when you assess it.
Help keep the planning information useful
If you spot an error, use the contact page and include the URL, the detail that needs attention, and a link to the announcement or first-hand evidence behind the correction. A clear description helps distinguish a lasting change from a temporary closure or a one-off event. For travel arrangements, keep your own confirmations and check directly with the operator or venue responsible. For entry permission, use the relevant official guidance for your passport and circumstances. ThaiTripPlanner brings planning material together, while those organisations remain the source for their own services and decisions.
