🚂 Getting Around Bangkok & Thailand

Bangkok has two airports — Suvarnabhumi (BKK) for most international flights and Don Mueang (DMK) for budget carriers. From Bangkok you can easily travel to Chiang Mai, Phuket, Koh Samui and more by train, bus, or domestic flight.

🛡️ Do You Need Travel Insurance for Thailand?

Yes — and it's especially important for Thailand. Healthcare in private hospitals (which are the best quality) is expensive for foreigners. Finnish Kela health insurance has zero coverage outside the EU and EEA. Travel insurance covering medical emergencies, trip cancellation and baggage is essential.
