Car rental (factual notes)

Summary

Renting a car is the comfortable, weather-proof way to explore Koh Samui, especially for families. International brands have counters at the airport and local companies operate around the island; you need your home licence plus an International Driving Permit, and driving is on the left.

Details

Typical costs

Indicative 2026 prices from travel sources: roughly 900-1,500 THB per day for a small car, more for SUVs and 4WD. International chains (Hertz, Sixt, Budget, Avis) have counters in the airport arrivals area per the airport transport page. Prices vary by season and company - compare and check what insurance is included.

Licence

Foreign drivers need their valid home-country driving licence plus an International Driving Permit (1949 or 1968 convention, physical booklet) covering the car category.

Insurance

Check the level of insurance included (third-party is the legal minimum; full coverage and excess waiver cost extra). Inspect and photograph the car at pickup.

Driving conditions

Driving is on the LEFT in Thailand. The ring road (4169) is paved and easy; the Chaweng-Lamai stretch is congested at peak times; the south-west 4170 road is steep, narrow and slippery when wet; some interior roads (e.g. to Secret Buddha Garden) need high clearance or 4WD.

Local tips

• Book ahead in high season (December-February); small cars sell out.
• Fuel stations sit on the ring road; Nathon, Chaweng and Lamai have the most.
• Parking at beaches and attractions is usually free or a small fee.
• A car is the practical choice for the quiet west and south coasts, which songthaews barely serve.

Safety

• Drive on the left; take extra care at junctions and roundabouts if you are used to right-hand driving.
• Watch for scooters - they are everywhere and can appear on either side.
• Avoid the steep interior and south-west roads in heavy rain.
