The crystal-clear waters around Koh Samui practically beg to be explored by boat. This Thai island’s most popular water excursions include day trips to Ang Thong National Marine Park, half-day catamaran adventures, and sunset dinner cruises. Our favorite outings combine snorkeling and island-hopping – especially the small-group tours to hidden coves that larger boats can’t access. Private yacht charters offer the most flexibility, though they’re pricey. The Marine Park tours stand out for their dramatic limestone cliffs and excellent kayaking spots.
