The longtail slips away from Thong Krut pier with a soft diesel rasp; salt and sea spray fling themselves across the bow and the shallow reefs loom like a pale carpet beneath the turquoise surface. In an hour the shoreline of Koh Tan appears — a low spine of white sand and coral — and beyond it the tiny white beach of Koh Madsum, where the island’s friendly pigs laze in the shade.

The longtail slips away from Thong Krut pier with a soft diesel rasp; salt and sea spray fling themselves across the bow and the shallow reefs loom like a pale carpet beneath the turquoise surface. In an hour the shoreline of Koh Tan appears — a low spine of white sand and coral — and beyond it the tiny white beach of Koh Madsum, where the island’s friendly pigs laze in the shade.
This half‑day excursion runs on local maritime tradition: the wooden longtail is both fishing skiff and island taxi, guided by crews who’ve worked these waters for generations. Geologically the area is coastal sandstone and reef limestone fringed by living coral; currents and seasonality shape the reefs you’ll snorkel. Culturally, Thong Krut remains a working fishing village with simple seafood cafés and sunset viewpoints — a contrast to Koh Samui’s busier beaches.
Expect clear, shallow snorkel sites with fringing coral gardens and abundant reef fish; life jackets and basic snorkel gear are provided. Morning departures usually offer calmer seas and better visibility; afternoons can bring breeze and chop. Practical notes: wear water shoes for rocky entries, apply reef‑safe sunscreen, and stow valuables in a dry bag. Respect wildlife — don’t touch coral or feed animals — and watch for changing currents when swimming off the boat.
This trip is compact and accessible: four hours of shoreline hopping, snorkeling, and a brief island stop to relax on white sand — an ideal half‑day to sample southern Koh Samui’s marine life and local seascape.
Yes — basic masks, snorkels and life jackets are provided, though some visitors prefer to bring their own mask for a better fit.
Sites are generally shallow and suitable for confident swimmers, but currents can change; always follow the crew’s guidance and wear a life jacket if unsure.
The pigs are used to visitors but should not be fed; approach calmly and avoid sudden movements to reduce stress on the animals.
Koh Madsum has a single local restaurant and limited shade; bring water and sun protection, though bottled water is included on the trip.
