Getting Around Koh Samui

Practical Travel Tips

01
Always carry an International Driving Permit if renting a scooter; police checkpoints are frequent.
02
Koh Samui is popular for Digital Nomads; utilize coworking spaces and high-speed Wi-Fi in Chaweng and Bophut.
03
Tipping is not mandatory but rounding up taxi fares or leaving 20–50 THB is appreciated for good service.
04
Dress modestly when visiting temples; cover your shoulders and knees to show respect.
05
Use ATMs wisely; Thai banks charge a 220 THB fee per withdrawal, so take out larger amounts at once.
06
Tap water is not drinkable; stick to bottled water which is widely available for 10–20 THB.
07
If you're also visiting other islands, consider planning a route to /ai-trip-planner/phuket or /ai-trip-planner/bali for a diverse regional experience.
08
Use Grab or Bolt apps to avoid price negotiation with local taxi drivers.
