These small-island tours off Koh Samui pack a lot into a single day. Boat excursions to Koh Madsum and Koh Tan deliver exactly what independent travelers want: uncrowded beaches, clear snorkeling spots, and authentic island experiences. I’m especially fond of the small-group speedboat tours – they’re efficient and hit all the right spots without the tourist crowds. The half-day private longtail tours are another smart choice, offering great value and flexibility for families.
Two standout options: The “Madsum Explorer” gives you prime beach time and excellent snorkeling, while the “Island Hopper” tour includes both islands plus a memorable lunch at a local fisherman’s house.
