Wat Sila Ngu, red temple Koh Samui (2026)

Getting there by scooter

From Chaweng I ride the ring road south. Lamai is the nearest coast town, and Wat Sila Ngu sits at the south end of that bay, by the beach, on the same stretch as the Hin Ta Hin Yai rocks. From the Lamai seafront I keep south along the coast. The temple itself is on level ground; the work is the hill before you get there.

Where scooters may stand changes with the day: see where bikes are already parked and read the entrance. Any 110–125cc automatic is enough for the grade. You still need a category A motorcycle license (a foreign one only together with an IDP showing A), and a helmet. Fines are an indicative range and change; check locally.

What you see and how long to stay

Wat Ratchathammaram is what the search for Wat Sila Ngu and the red temple Koh Samui is pointing at. I come for the red sandstone and the stair with nagas, and for the beach at the gate.

I plan 20–40 minutes. Add time only if you sit by the water afterwards. Shoes come off before the stair. Covered shoulders and knees are the usual temple rule; the board at the entrance wins if it says something else. I do not have a fee or opening hours to quote — check the gate, both change. If the gate is closed, the visit is over and I ride on.

The colour of the stone against the sea is the whole stop. For height and a long stair, Big Buddha on the north coast is a separate ride.

When to go

Morning and late afternoon are when the red sandstone shows its colour. Around noon the east-coast sun glares off the yard, and I would not count on much shade. I aim to arrive before 10, or after 15:30. The beach beside the temple takes the morning light, which is why I prefer the early stop.

October to December brings the wet season. Showers often build after lunch. The yard is open to the weather, so a downpour ends the visit. The part I watch is the hill between Chaweng and Lamai: expect a slick surface in the first minutes of rain. I keep this ride in daylight.

A clear midday still works if you keep the stop short and carry water.

What to combine it with

The mapped routes on this site do not list Wat Sila Ngu as a stop. I still add it on the Lamai section of the ring road, because Hin Ta Hin Yai is at the same south end of the bay. The rocks and the stair are one pause, in either order.

Lamai Viewpoint is the deck on the hill above that bay. Coming south from Chaweng, I take the deck while I am already climbing, then drop to the temple. Guan Yu is the marker if I continue south. Wat Samret and then Wat Khunaram lie further along that south-coast run.

For the full loop I follow the ring road and treat the red temple as an extra stop in the day. When I want several temples, I open the temples route and check the order on that map. That loop is Big Buddha, Plai Laem and Khao Hua Jook; it does not pass this gate.
