The one thing nobody tells you about visiting Koh Lanta, Thailand
After traveling to 30+ countries, there's one thing I wish someone had told me from day one, and it completely changed how I experience new cities.
Free walking tours. Yes, actually free. No credit card needed. No catch.
You just show up and a local guide takes you around for 2-3 hours. All the major sights, hidden gems, local stories. Here's the thing: guides work entirely on tips. If they do a bad job, they don't get paid. So they bring their absolute best every single time. Passionate storytelling, insider tips, restaurant recommendations you won't find on Google.
At the end, you tip whatever feels right. Most people give around €10-15, which is a fraction of what traditional tours cost for a much better experience.
I've done these in dozens of cities and they've been the highlight of almost every trip. If you're visiting Koh Lanta, Thailand, do this on your first day. You'll thank me later.
