Why go, and how to do it well
Tucked away from Koh Samui's busier stretches of coastline, Thongson Beach earns its reputation as one of the island's more peaceful natural escapes. The surrounding hillside provides natural wind protection, keeping conditions calm even when other beaches are breezy, while palm trees offer generous shade along the shore. The beach attracts visitors looking for a genuinely unhurried day by the water rather than the organized activity and crowds found elsewhere on the island.
The atmosphere here is quietly social — suited to swimming, sunbathing, and simply sitting with a view. The water is generally clear and inviting, and the beach is accessible enough for a half-day visit from other parts of Koh Samui. A short walk east along the shore leads to a quieter stretch where visitors report even prettier water. Jet ski rental is available at the beach, though some visitors have had poor experiences with operators cutting sessions short, so it pays to clarify terms before booking.

Reviews from Google
Decided to visit this beach that I had totally overlooked each time I visited Koh Samui. It was a good choice to visit as this is probably one of the most wonderful beaches on the island. The water is really clear and it's a good place to swim and relax. The water is also very shallow, which allows the water to be pretty warm. Definitely worth visiting!
One of the more quiet beaches of Koh Samui. You won’t notice if there’s a lot of wind because it is “protected” from the hill. There are plenty of spots with shade from the palmtrees. Only at the end to get there, there is a sand road. But not difficult to drive.
DO NOT JETSKI HERE – SERIOUSLY, DON’T. Read why: I usually jetski here without any problems, but today was just ridiculous. I had been riding for barely 8 minutes(booked 20 min) when the jetski suddenly stopped working. Later we found out there was plastic stuck inside the engine because people pollute the ocean. Because of that, I could only drive back at around 8 km/h — no speed, no fun, nothing. After about 15 minutes struggling back, I finally reached the beach. We then asked, very normally, if I could get maybe 10 more minutes since I only had about 8 minutes of real jetski time before it broke. My Thai girlfriend explained it politely… and then one of the guys suddenly got angry at her. He even asked if we “had a problem,” acting like he wanted to start a fight. The woman there said it was my fault and that they couldn’t do anything. Absolutely unbelievable. I normally jetski here with fun, but this was just shameful. Unfriendly people, zero responsibility for their own equipment, and they even try to blame you. Never jetski here. Horrible service and plenty of other places where they treat you like a human being.

Tips for Visiting Beaches
Go Early for Empty Sand
Even the busiest beaches are nearly deserted before 9 AM. A sunrise walk is the best hour of the day on the sand, and you'll beat the heat for a morning swim.
Use Reef-Safe Sunscreen
Many Thai marine parks ban chemical sunscreens that damage coral. Bring reef-safe (mineral/zinc-based) sunscreen from home — it's harder to find and pricier in Thailand.
