Koh Samui in a day by scooter — the one-day classic (2026)
This is the route I give friends who have one free day and a rented scooter: the two big temples in the north-east, the east coast down to Lamai, a swim at Na Muang and, if the road is dry, the climb to the Secret Buddha Garden. It is 54.5 km of riding: the ring road down the east coast, then a very steep hill road by the Secret Buddha Garden that decides how your day finishes.

Climbs and descents
Across — kilometres from the start, up — metres above sea level; the numbers at the bottom are the stops listed below. Bars under the chart and the yellow-and-black stretches on the map mark steep sections (over 12 %, dark red over 20 %). Elevation comes from SRTM satellite data, smoothed: an estimate, not a measurement on the road.

Come before 10 when it is cooler and quieter; leave the scooter at the parking by the causeway and take off your shoes at the stairs.

The lower fall is a short walk from where you park; bring a towel if you plan to swim.

Very steep access road: ride it only when dry, solo if you are unsure. Entry is about 80 baht.
The ride in numbers
| Distance | 54.5 km as mapped, from Chaweng through all seven stops. The ride back to your hotel comes on top and depends on where you stay. |
|---|---|
| Riding time | About 1.5 hours of pure riding at a relaxed 40 km/h. With stops it is a full day: leave around 8:30, be off the hill by late afternoon. |
| Road | Mostly the ring road 4169 and the short side roads to Big Buddha, Hin Ta Hin Yai and Na Muang. The road up to the Secret Buddha Garden is very steep in places, and the way down is very steep too. |
| Scooter | A 125cc automatic. A 110cc handles the coast fine but will struggle on the final climb, especially two-up. More on that in 50cc or 125cc. |
| Direction | As mapped: north to the temples first, then south along the east coast, then inland to the hills. Temples in the cool morning, water in the heat, the hill last. |
Where to be careful
- Chaweng, twice. The route crosses Chaweng going north and again coming south. This is the busiest traffic on the island. Look twice before pulling out.
- Lad Koh. The viewpoint is a short, steep climb between Chaweng and Lamai. Pull fully off the road and check both directions before rejoining.
- Rain. October to December brings sudden showers; the first minutes on wet asphalt are the slippery ones. See rain and night riding.
- Paperwork. Thai law requires a motorcycle licence (category A; a foreign one only together with an IDP showing A) and a helmet.
How to ride it, stop by stop
- Big Buddha (Wat Phra Yai), around 9:00, before the heat and the crowds. Cover shoulders and knees. 30–40 minutes.
- Wat Plai Laem is a couple of minutes away. Half an hour is enough, then ride back south through Chaweng.
- Lad Koh Viewpoint — a short stop for the east-coast view, 10–15 minutes.
- Lamai Beach — the long stop of the day: lunch and a swim, 1–1.5 hours.
- Hin Ta Hin Yai — a short detour at the south end of Lamai. 20 minutes; expect it busy around midday.
- Na Muang Waterfall 1 — the road turns inland. The lower fall has a pool, good for cooling off in the early afternoon. The road in is very steep in places. About 45 minutes.
- Secret Buddha Garden — the climb. Plan 45 minutes to an hour up there and start down while it is still light: the road down is very steep in places.
GPX and navigation
The GPX above is cut from my own GPS log, so it follows the turns exactly as I rode them, including the road up to the Secret Buddha Garden. Load it into Organic Maps, OsmAnd, Maps.me or a Garmin and it works offline. Google Maps does not open GPX files; tap a stop on the map and use Directions instead.
A phone mount and a power bank make the day easier: navigation all day drains a battery faster than you expect.
If something goes wrong: 1669 for an ambulance, 1155 for the Tourist Police.
Questions
Can you see Koh Samui in one day by scooter?
You can see the classics: the two big temples, the east coast, a waterfall and a hill garden. You will not see the whole island; the west and south coasts need another day.
How long does the one-day route take?
About 1.5 hours of riding for 54.5 km. With stops, lunch and a swim, plan from around 8:30 to late afternoon.
Is the road to the Secret Buddha Garden OK on a scooter?
On a 125cc in dry weather, for a confident rider, yes. Two-up, on a 110cc, after rain or if you are a beginner, I would skip it.
Do I need a licence to ride this route?
Yes: Thai law requires a motorcycle licence (category A; a foreign one only together with an IDP showing A) and a helmet. Fines change, check locally.
