Transport is freedom on Koh Samui. Without your own vehicle you are tied to a few streets in Chaweng or to expensive taxi drivers. With a motorbike or car, the whole island opens up. But there are rules and quirks — and it is better to know them in advance.

Motorbike or Car: How to Choose

The choice depends on several factors:

  • Family or children: car. A motorbike with children is an unjustified risk on the island's normal roads.
  • Rainy season (October–November): car. Fast-moving downpours make motorbike riding dangerous.
  • One person or a couple, dry season: motorbike — fast, cheap and easy to park.
  • Limited budget and short trips: motorbike (2,500–3,500 THB/month) vs car (from 12,000 THB/month) — the gap is significant.

Motorbike Rental

Motorbikes are rented virtually everywhere: at every tourist-facing hotel and at every major junction. Typical terms:

  • Standard Honda Wave scooter (110cc): 200–350 THB/day; 2,500–3,500 THB/month
  • Honda Click semi-automatic (125cc): 250–400 THB/day
  • Trail or off-road bike (from 150cc): 400–800 THB/day
  • Deposit: 500–1,500 THB or a passport (better to leave a cash deposit rather than your passport)

Essential: photograph all existing scratches and damage before the rental starts. Send the photos to the rental company via WhatsApp — this is your protection on return.

Car Rental

Major international rental companies (Budget, Hertz) operate at the airport and in Chaweng. Local companies often offer more flexible terms and cheaper long-term rates.

  • Small car (Toyota Yaris/Honda Jazz): 800–1,200 THB/day; 12,000–18,000 THB/month
  • Crossover/SUV (Honda HR-V, Toyota C-HR): 1,200–2,000 THB/day; 18,000–30,000 THB/month
  • Pickup (Toyota Hilux, Ford Ranger): 1,000–1,800 THB/day — popular among long-term residents

Documents and Insurance

Technically, riding a motorbike in Thailand requires a Thai licence or an international driving permit with category A (motorcycle). Police check documents on the island's roads: the fine for riding without a licence is 500 THB — but that is the least of the consequences in an accident.

Car rental insurance: basic insurance is usually included but has limited cover. An additional CDW (Collision Damage Waiver) costs 150–300 THB/day and removes financial liability in an accident.

Motorbike rentals typically have no insurance. This is important to understand: in an accident, you bear the financial responsibility yourself. This is precisely why travel insurance covering traffic accidents is essential.

Driving Peculiarities on Samui

Several things you need to adjust to:

  • Traffic drives on the left — unfamiliar for most Europeans for the first few days
  • Mountain roads in the island's interior — steep, sometimes slippery, with blind bends. Slow down.
  • Potholes on secondary roads — a reality in rainy season. Watch the road surface.
  • Dogs sleeping on roads — especially at night. Steer around them; do not brake sharply.
  • Thai drivers are not aggressive but can be unpredictable — keep your distance.

Petrol Stations and Fuel

Petrol stations appear every 5–10 km on the ring road. PTT and Caltex are the most common chains. 95-octane petrol (used by most scooters) costs 45–50 THB/litre (2026). Payment by card or cash is accepted at stations.

SamuiDays can, if needed, help arrange a car or motorbike rental through verified local partners with honest contract terms.
