A squat speedboat slips away from Koh Samui's palm-lined shore and the horizon widens into the Gulf of Thailand. Salt cuts the air; the engine's staccato and the spray set a brisk tempo as islands resolve from heat haze. By midmorning the boat ties up at Koh Taen, where shallow reefs fan out in clear water and coral bommies attract schools of parrotfish and angelfish.

A squat speedboat slips away from Koh Samui's palm-lined shore and the horizon widens into the Gulf of Thailand. Salt cuts the air; the engine's staccato and the spray set a brisk tempo as islands resolve from heat haze. By midmorning the boat ties up at Koh Taen, where shallow reefs fan out in clear water and coral bommies attract schools of parrotfish and angelfish.
Koh Taen (Ko Taen) sits roughly five kilometers south of Samui and is geologically a low-lying sandstone and coral island—ideal for snorkeling where reefs lie close to shore. Nearby Koh Madsum, recently nicknamed Pig Island, offers a long white sand spit and a curious local cast of semi-wild pigs that forage at the treeline. Both islands belong to the Samui archipelago, historically a mix of fishing hamlets and coconut plantations; today they balance small-scale local life with day-trip tourism.
Expect two to three snorkel sessions, a beach stop for lunch and free time to walk the sand or kayak. Practicalities matter: the tour runs about 6–7 hours with hotel pick-up from main Samui resorts, life jackets and snorkeling masks provided, and a Thai set-lunch served aboard or ashore. Water is warm year-round; visibility peaks in the dry season.
Bring reef-safe sunscreen, a lightweight rashguard, and a waterproof pouch for your phone. Keep interactions with pigs hands-off—feeding disrupts their behavior—and respect coral by not standing or touching. For a single-day taste of Samui's marine life and a memorable encounter with Pig Island, this speedboat loop is efficient, scenic and accessible to most swimmers.
easy.
6–7 hours.
Light aerobic fitness and basic swimming ability are sufficient; people should be comfortable in shallow open water.
The tour provides snorkeling masks and life jackets; if you prefer your own gear bring it for fit and comfort.
Yes—life jackets are provided and much snorkeling is in shallow water, but non-swimmers should remain with the guide or on the boat during deeper stops.
The pigs are semi-wild and can be skittish or aggressive if cornered; observe from a distance and avoid feeding them.
A Thai set menu is served with soft drinks and fresh fruit; special dietary requests should be noted during booking.
These isles were traditionally fishing and coconut-growing outposts of the Surat Thani coast; increased day tourism has reshaped some local economies.
Coral reefs here are sensitive—use reef-safe sunscreen, avoid standing on coral, and decline feeding wildlife to reduce ecological stress.
