You push off from Ban Phe as the morning light slices across the Gulf of Thailand, the boat's bow cutting a bright path toward small islands that rise from turquoise water. Salt air and the hum of an outboard set the pace; palms on distant shores lean toward the sea as if to watch you pass.
These islands—Koh Kudi, Koh Tham Tai Khao, Koh Khame, Koh Krawai, Koh Thalu and the ribbon of Koh Plai Tin—are low-lying limestone and sand bars punctuated by coral gardens. The area sits within the Mu Ko Samet island group, long used by local fishing communities and now visited for clear-water snorkeling and the curious “sea split,” a tidal channel that briefly divides a beach.
Culturally the coast is straightforward: small fishing piers at Ban Phe and simple island life shape the itinerary—short swims, guided snorkel stops, and a beachside lunch option on longer departures. Underwater, hard and soft corals host reef fish; above water, winds sweep warm, exposed beaches and shady coves in alternating moods.
Practically: expect a 6‑hour shared-boat day with hotel pickup from Rayong/Ban Phe, provided life jackets and snorkel gear, and snacks and drinks. Bring reef-safe sunscreen, a light rash guard, and a waterproof camera or phone housing—the operator often supplies free underwater photos. Currents can be noticeable at some sites; follow the crew’s guidance, stay with the group, and conserve energy between swims. Timing your visit for morning departures reduces boat traffic and improves visibility, while a moderate level of fitness makes transfers and repeated short swims comfortable.
The shared tour runs about 6 hours and typically includes hotel pickup from Ban Phe, snorkeling equipment, life jackets, snacks, drinks, and for the 6‑island option, lunch.
Basic swimming and mask‑snorkel comfort are recommended; crew provides briefings and life jackets for less confident swimmers.
Yes—many stops are shallow reef flats good for beginners, but some areas have currents so follow crew instructions and stay with the group.
Yes—the operator cancels for unsafe sea conditions; check the 24‑hour cancellation policy for refunds.
