Koh Madsum is known for its small herd of pigs that wander the shouldered shoreline, curious and unbothered by visitors. Koh Tan’s shallow flats expose sandbars at low tide and support seagrass beds that protect juvenile fish. Geologically these islands are uplifted sandstone and coral outcrops shaped by currents and monsoon swells; historically they belong to fishing communities linked to Koh Samui’s coconut and maritime trade.
Plan for snorkeling in reef zones—currents can tug at limbs, and coral sits only a few meters below the surface. Wear reef-safe sunscreen and a snorkel vest if you need added buoyancy. Expect short hops between stops: lounging on Rap, snorkeling off Tan, and a relaxed shore visit where pigs amble on Madsum. Photography is best in morning light; afternoons bring more chop.
Practicalities: tours run 5–6 hours, operators provide life jackets, bottled water, and basic snorkel gear; bring a dry bag, cash for small beach vendors, and a compact first-aid kit. Arrive early to avoid crowds, check tide times, and confirm hotel pickup—many operators include a short transfer from Chaweng and Bophut.
Respect wildlife—do not feed pigs or touch coral—and time your trip outside heavy monsoon months for calmer seas.
Yes—basic snorkel masks, fins and life jackets are included, though many travelers bring their own mask for fit and comfort.
Yes; the trip is family-friendly. Infants must sit on an adult’s lap and life jackets are provided for all ages.
