The sun breaks over the Gulf of Thailand and the speedboat surges forward, spray spitting at the bow as Koh Samui recedes behind you. Sea and sky trade blues; palms wink on the shoreline. You’re heading into open water where dolphins often arc through the swell, then toward coral-fringed isles where sand and curious pigs wait.

The sun breaks over the Gulf of Thailand and the speedboat surges forward, spray spitting at the bow as Koh Samui recedes behind you. Sea and sky trade blues; palms wink on the shoreline. You’re heading into open water where dolphins often arc through the swell, then toward coral-fringed isles where sand and curious pigs wait.
This route threads local maritime history—fishing villages and coconut groves long tied to Surat Thani Province—through geology of uplifted limestone and volcanic sediments that shape the shallow reefs. Koh Tan’s reefs are shallow, sun-warmed and full of branching corals and reef fish; the sandy coves of Pig Island (Koh Madsum) host the small domestic pigs that have made the beach their domain.
Expect wildlife viewing from the boat: dolphins typically surface in groups, moving fast and sometimes riding the bow wave. Snorkeling on Koh Tan is flatwater and beginner-friendly; visibility is best in calm seas. The tour includes life jackets, snorkeling equipment, a buffet lunch and transfers from main Koh Samui resorts.
Practical guidance: arrive hydrated and sun-protected; the boat ride can be bumpy, so seasickness meds help. Use reef-safe sunscreen and avoid feeding wildlife—pigs and fish fare poorly on human food. Bring a waterproof camera or dry bag for phones, and shoes for rocky shorelines. Peak season is December–March for calm seas and clearer snorkel conditions, while monsoon swells (May–October) can make dolphin sightings and snorkeling rougher. The trip is family-friendly but not recommended for pregnant travelers or those with serious back or heart conditions.

These islands are part of Surat Thani’s maritime landscape, long used by local fishermen; Koh Samui grew into a tourist hub from coconut plantations and small fishing ports.
Use reef-safe sunscreens, avoid touching coral, and don’t feed wildlife—local operators encourage low-impact visits to protect fragile reef and island ecosystems.
