Thailand’s Koh Samui shines brightest from the water. The island’s boat tours range from basic group trips ($40-80) to exclusive yacht charters ($500+). After exploring dozens of options, I’m most impressed by the Ang Thong National Marine Park day trips – they offer the best balance of value and experience. The morning departures come with fewer crowds, while afternoon tours catch stunning sunsets.
I particularly love the small-group speedboat tours to Koh Tao. These intimate excursions (max 15 people) include quality snorkel gear, a Thai lunch, and strategic timing to avoid the big tour crowds. For those seeking luxury, the private sunset cruises along Koh Samui’s west coast deliver five-star service and unmatched views.
