The longtail’s engine ticks and the island-smoothed horizon opens as you push off from Thong Krut — sunlight skimming the bow and the sea daring you toward a chain of small islands south of Koh Samui.

History
Koh Tan and surrounding islets are traditional fishing grounds for Samui communities; Koh Madsum gained the nickname “Pig Island” after local pigs were introduced and became a quirky tourist attraction.
Conservation
Coral reefs here are sensitive; choose reef-safe sunscreen, avoid standing on coral, and carry out all trash to minimize impact.
Reserve your spot on the Private Longtail Boat Tour to Koh Madsum and Koh Tan with Lunch today and enjoy a trusted, highly rated experience designed to help you make the most of your adventure.
Morning trips for best visibility
Book a morning departure — water tends to be calmer and snorkeling visibility is clearer before winds build.
Wear reef-safe sunscreen
Corals are fragile; use reef-safe sunscreen and reapply on the boat rather than in the water.
Bring water shoes
Landings can be on sand, rock or coral rubble — water shoes protect your feet when stepping ashore.
Secure seasickness remedies
Longtail boats are small and can roll in open water — take motion-sickness meds beforehand if needed.
Reef-safe sunscreen
Protects coral and prevents sunburn during prolonged exposure on deck and shore.
Water shoes
Useful for rocky landings and reef-scrubbed beaches where sandals aren’t safe.
Lightweight swim towel or quick-dry towel
Dries fast on a small boat and during island stops.
Personal snorkel mask
Although snorkel gear is provided, a well-fitting personal mask improves comfort and fog resistance.
