You step off the pier and feel the boat shift beneath your feet; the Gulf of Thailand spreads flat and bright, the water daring you to come closer. The cruise peels away from Koh Samui’s coastline and the engine hum drops to a steady lull that lets the sea set the pace.

Koh Rap, Koh Tan and the small ‘Pig Island’ near Samui are part of an archipelago shaped by shallow coral shelves and limestone outcrops. The islands have long been summering grounds for fishermen and coconut growers—today those same waters host reefs that feed tropical fish and occasional green turtles. Local crews still ferry visitors with the same practical hospitality the islands are known for.
On the water you’ll trade sand for spray: reef flats give way to pockets of alive coral, and currents push you along sheltered channels where visibility can be excellent in the dry months. The so-called Pig Island is an odd cultural footnote—feral pigs that swim ashore draw attention but should be respected as wild animals.
Practical guidance: the trip runs about six hours and includes snorkel gear, paddle board options and light refreshments; bring a fitted mask if you prefer, reef-safe sunscreen, and a simple waterproof pouch for phones. Time your cruise for midmorning or early afternoon for calmer seas and clearer water; avoid heavy monsoon days if you want the best visibility. Stay hydrated, secure loose items, and follow the crew’s brief on reef-friendly behavior—small actions matter for fragile coral and wildlife.
Yes—basic snorkel masks, fins and life vests are provided, though some guests prefer to bring personal masks for fit and comfort.
Yes—life vests are provided and crew stay close; however non-swimmers should remain in shallow areas or on board when reefs are deep.
No—pigs are wild and can behave unpredictably; keep a safe distance and follow crew guidance at all times.
