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 25 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 25 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.
