Departure points depend on the trip and the route. Private speedboat charters leave from Bophut, and we'll confirm the departure point and meeting time for every trip when you book.

When is the best time for a boat trip?

Seas around Koh Samui are usually calmest from February to September. October to December is the rainy season, when some trips are rescheduled. See our Koh Samui weather guide.
