The engine wakes before dawn and the pier smells of diesel and grilled fish. Within minutes a speedboat cuts through glassy water, spray stinging your cheeks, and the low silhouette of Koh Tan and Koh Madsum grows from the horizon.

The engine wakes before dawn and the pier smells of diesel and grilled fish. Within minutes a speedboat cuts through glassy water, spray stinging your cheeks, and the low silhouette of Koh Tan and Koh Madsum grows from the horizon.
Koh Tan sits as a small outcrop of granite and coral; reefs fan out in shallow turquoise around it. Koh Madsum—known locally as Pig Island—adds a quirky cultural note: a few resident pigs wander its sand and greet visitors. These islands sit off Koh Samui’s southern coast in Surat Thani province, a region shaped by volcanic rock and coral growth over millennia and influenced by Thai fishing communities for generations.
Expect clear snorkeling spots populated by reef fish, occasional sea turtles, and sheltered beaches for a lazy lunch. The day moves in clear beats: a quick 7–10 minute run from Thong Krut Pier, a snorkeling stop in front of Koh Tan where guides point out coral gardens, then a relaxed shore visit to Koh Madsum for photos and a short walk among palms.
Practical notes: trips run 4–5 hours, and operators commonly provide life jackets, bottled water, and snorkel gear. Bring reef-safe sunscreen, a swim shirt, and water shoes for uneven reef and rocky shorelines. Morning departures avoid afternoon winds and offer calmer seas and clearer water for visibility. Respect the reefs—no touching—and follow crew guidance when entering the water.
This private run is ideal for families or small groups wanting focused time on snorkeling and uncrowded beaches without the pace of larger ferries.
