The sun hits the bay low and hot as the speedboat cuts a white wake toward two tiny islands just off Koh Samui. On Koh Madsum—commonly called Pig Island—pigs amble across soft, white sand as the sea tugs at your ankles; wind and water trade places, and the whole island feels like a live postcard. A short hop away, Koh Tan unspools a different mood: shallow coral gardens, clear water, and tropical fish that flicker like living confetti.

Tours may be canceled for safety; most providers offer rescheduling or a full refund if the operator calls off the trip due to weather.
Local fishing communities on Koh Samui’s south coast have long run small-boat day trips; the islands remain low-impact, visited mainly for day excursions rather than development.
Coral reefs here are sensitive to anchor damage and sunscreen chemicals; choose operators who use moorings, avoid touching reefs, and promote reef-safe sunscreen use.
