Discover Koh Samui in your language — a French-Thai team at your service since 2020
Finding a French-speaking guide in Koh Samui is not easy. Most tour operators offer excursions in English or Thai only. At Samui Authentic, French is not an afterthought — it's at the heart of everything we do. Our founder notre fondateur built this company specifically to serve French-speaking travellers.
Why does language matter on a boat excursion? Safety first: understanding the captain's instructions in choppy waters, knowing which areas are safe for snorkeling, what to do if you see a jellyfish. But beyond safety, language transforms the experience. Your guide shares the stories behind the islands, the legends of the fishermen, the hidden spots that don't appear in guidebooks.
Our French-Thai team bridges two cultures. notre fondateur lives between France and Thailand, nos capitaines and the captains know every reef and every cave. Together, they offer you the authentic Koh Samui experience — explained with the nuances, humor, and precision that only your native language can provide.
Understand every safety instruction clearly. From boat procedures to snorkeling guidelines, nothing gets lost in translation when your life vest depends on it.
Ask any question, express any need. Dietary requirements, medical concerns, special requests for your children — communicate naturally without searching for words.
Your guide shares the local history, Thai traditions, and island legends in the richness of French. The stories behind the places make the excursion unforgettable.
Best restaurants, hidden beaches, markets to visit, scams to avoid. Your francophone guide gives you the real insider tips — the ones you won't find on TripAdvisor.

Samui Authentic was founded by notre fondateur, a Frenchman who fell in love with Koh Samui and decided to create the excursion experience he wished had existed when he first arrived. Tired of impersonal, overcrowded tours where no one spoke French, he built a team that combines Thai local expertise with French hospitality.
Today, our team includes 4 Thai employees — captains, drivers, and local guides who know every island, every reef, every hidden beach. Combined with notre fondateur's French-speaking guidance, you get the best of both worlds: local knowledge delivered in your language.
