Koh Samui Airport (USM) is incredibly charming (open air, thatched roofs), but it is privately owned by Bangkok Airways, meaning flights directly to the island are completely monopolized and famously expensive.

⚠️ Conseils de Voyage Essentiels Koh Samui
Avoid the Expensive Flights
To avoid the expensive direct flights to Koh Samui, fly into Surat Thani (URT) on the mainland (via AirAsia), then buy a cheap bus+ferry combo ticket to cross over to the island.
Watch the Sand on the Ring Road
If renting a scooter, be hyper-aware that the edges of the ring road are often coated in loose sand. Taking a corner too fast will immediately cause you to wipe out.
Sunset on the West Coast
The main beaches (Chaweng/Lamai) face east. For incredible sunset views, rent a scooter and drive to the quieter west coast (Nathon or Taling Ngam) to drink cocktails at an oceanside bar.
Get a Beach Massage
The open-air massage 'salas' directly on the beach are incredibly relaxing. Listening to the waves while getting a Thai massage for $10 USD is the ultimate Koh Samui experience.
🛡️ Assurance Voyage Recommandée
Get travel insurance for peace of mind.
