Koh Samui scooter FAQ (2026)

This Koh Samui scooter FAQ is what I tell friends before they rent: licence, helmet, money, time, rain, and what to do if you fall. I live on the island; distances come from my log, about 800 km and 32,000 GPS points. If a fine or a price moves, I say check it locally.

Whole island track (GPX, 2.5 MB)

Colour — all the routes on this site (list under the Routes button on the map), faint — every road I have ridden. GPX works in Maps.me, Organic Maps, OsmAnd, Garmin.

Licence, IDP, helmet and police

A scooter is a motorcycle under Thai law: category A — a foreign one only together with an IDP showing A, and a helmet. A car licence, or an IDP with only B, does not cover you. An IDP only translates a class you already hold. Carry it with the home licence.

The mistake. Many shops never look at your licence. That does not make the ride legal. More is on the riding without a licence page.

Will the police stop me? Expect it sometimes, not every ride. I keep the licence in a pocket.
How much is the fine? No helmet: up to 2,000 baht, and up to 4,000 for the rider if the passenger has none. No licence with you: up to 1,000 baht. Those are the maximums.
Is the shop helmet enough? Yes if it is strapped on. A torn strap means ask for another.

Deposit, daily cost, which scooter

Agree the money before you ride. A 125cc automatic is roughly 140–350 baht a day — Chaweng and Lamai at the top of that range, Maenam, Bophut and Nathon at the bottom. A week is roughly 900–1,800 baht. Prices move — check locally. I compare offers on the price page.

Passport or cash deposit? Commonly 1,000–3,000 baht cash plus a passport copy; some shops ask for the original passport. I leave cash and a copy, and I photograph the contract.
50cc or 125cc? A 110–125cc automatic is enough for the ring and calmer in traffic than a 50cc at full throttle. A 50cc suits some beginners and is weak on steeper roads.
First scooter? Automatic, not a big bike. If it has been years, say so and take ten minutes on a quiet road first.

Safe or not, one day, the loop

Is it safe to ride a scooter in Koh Samui? Yes on the easy roads if you already ride: keep left, stay near 40–50 km/h and skip the night. Easy rides in my log: ring 63.7 km, north coast 27.2 km, south-west 36.3 km, temples 24.7 km. Mountain is 45.7 km and hard. A new rider should stay on that list.

How long does it take to drive around Koh Samui? The ring is about 1.5 hours non-stop. With a stop and lunch, half a day. Notes sit on the ring road page.
Is one day enough? For a first look, yes: 54.5 km, medium. Not with waterfalls (69.3 km) or the mountain.
Rain, October to December? Heavy showers, not always all day. The first minutes are slick; I wait under a roof.

Fuel, parking, dogs, a crash

Fuel is petrol, from stations and from bottle stands at the roadside. On the ring you are rarely far from either; I still start with a full tank. Park where scooters already stand, off the lane. I have not paid a formal fee; if someone asks, check on the spot.

Dogs? They lie on warm asphalt after dark. Slow down for a dark shape. I finish before night.
After a crash? Leave the lane if you can. Hurt: call 1669. A report or a dispute: Tourist Police 1155. Photos, then the rental shop. Do not sign what you cannot read. The accidents page goes further.
Does rental insurance count? Treat it as your deposit. Travel cover often skips scooters, or skips you with no motorcycle licence. Read the policy first.

Importing a GPX

Route pages here include a GPX from my own log, so the line is the road I rode. The ring file is 63.7 km, the one-day classic 54.5 km, viewpoints 38.3 km, waterfalls 69.3 km. Import that file. Do not redraw it from memory at the roadside.

Which app opens a GPX? Maps.me, Organic Maps, OsmAnd or a Garmin, offline once the island map is downloaded. Do that on hotel wifi.
Will Google Maps import GPX? No. Use directions to a stop named on the route page, or use an app that reads the file.
Why does the line leave the road? That is a detour to a stop. For the through-route only, rejoin where it returns.

Load the GPX the night before.

Questions

Is it safe to ride a scooter in Koh Samui?

Yes on the easy roads if you already ride, stay near 40–50 km/h and avoid the night. Traffic and the first wet minutes cause more trouble than the hills.

How long does it take to drive around Koh Samui?

About 1.5 hours non-stop on the 63.7 km ring. With stops, half a day. One day is a first look, not every beach and the hills.

What licence do I need to rent a scooter on Koh Samui?

A motorcycle licence, category A — a foreign one only together with an IDP showing A, and a helmet. A car licence is not enough. Shops may rent anyway. Fines change — check locally.

How much is a scooter per day, and do they keep my passport?

Roughly 140–350 baht a day for a 125cc automatic; a week is roughly 900–1,800 baht. Prices move — check locally. A cash deposit of roughly 1,000–3,000 baht plus a passport copy is common; some shops ask for the original passport. I offer cash and a copy.
