Cars in Koh Samui — 2026 Price Guide
* Prices are indicative. Actual prices vary by season, duration and availability. Long-term rentals (7+ days) typically receive 10-20% discount.
What You Need to Rent a Car in Koh Samui
Mandatory in Thailand. Your home license alone is not valid. Get your IDP from your national automobile association before departure — takes 5 minutes and costs ~$20. Without it, your rental insurance is void.
Required at pickup. Rental companies in Koh Samui will hold a copy of your passport as part of the rental agreement. Make sure your passport is valid for the entire rental period.
Required for the security deposit — usually 5,000-15,000 THB depending on vehicle category. Debit cards are generally not accepted. The hold is released at vehicle return in good condition.
Car rental insurance covers the vehicle — but not you. Make sure your travel insurance covers driving accidents in Thailand. If you don't have one, get SafetyWing or Pacific Cross before you drive.
Driving in Koh Samui — What Locals Know
Thailand drives on the left — same as the UK. The coastal ring road is easy to navigate. Take it slow the first day especially at roundabouts.
Interior roads are steep and narrow. During rainy season (Oct-Dec) they can be slippery. Stick to the ring road if you're not confident.
Koh Samui gets heavy rain especially in October-December. A car is significantly safer than a scooter in wet conditions.
Police checkpoints are common near Chaweng. Always have your passport, IDP and rental agreement in the car. Fines are 500-1,000 THB.
PTT and Shell stations are plentiful around the ring road. Petrol costs ~40-45 THB per litre. Return the car with a full tank to avoid penalties.
Always photograph every scratch and dent before driving off — with the rental agent present. Share the photos with Discover Cars support immediately.
Discover Cars insures the vehicle. But a single hospital stay after a road accident in Koh Samui without personal health insurance can cost $5,000-$20,000. Don't drive uninsured — it's not worth the risk.
