The day begins with a harbor breeze and the engine’s steady thrum as a private speedboat slips away from Koh Samui toward a cluster of islands that seem to rise from the Gulf like old limestone crowns. The sea pushes you onward; waves clip the hull and the crew points toward the jagged silhouette of islands coming into focus — beaches, cliffs and a deep emerald lagoon framed by steep rock.

The day begins with a harbor breeze and the engine’s steady thrum as a private speedboat slips away from Koh Samui toward a cluster of islands that seem to rise from the Gulf like old limestone crowns. The sea pushes you onward; waves clip the hull and the crew points toward the jagged silhouette of islands coming into focus — beaches, cliffs and a deep emerald lagoon framed by steep rock.
Ang Thong National Marine Park, created in 1980, is a 42-island archipelago dominated by limestone karsts, sea caves and sheltered coves carved by centuries of waves. The park is part of Surat Thani’s marine landscape and supports traditional fishing villages nearby; on the islands you’ll find sparse, protected beachside restaurants serving Thai staples.
Expect a day that balances motion and stillness: snorkeling on coral-fringed reefs at Koh Wao, a coastal cruise past serrated cliffs, a short hike to a viewpoint overlooking the emerald lake, and time for a swim or guided kayak. Guides will brief you on local ecology — the fragile corals and how the park entrance fee supports preservation.
Practicalities matter: the trip normally runs about eight hours with hotel pickup in the morning. Pack reef-safe sunscreen, a light waterproof bag, and a reusable water bottle. If seasickness affects you, take medication beforehand and pick a morning cruise when the water is typically calmer. Bring cash for the national park entry fee and optional kayak rental. With planning, this private speedboat day is a hands-on way to experience Thailand’s offshore wilderness — fast, vivid and rewarding.
Yes — the tour is family‑friendly; life jackets are provided, but check age limits for kayaking and consider the boat transfer time for young children.
The park charges an entrance fee paid on arrival (typically around 300 THB per adult); confirm the current rate before travel as fees can change.
No formal training is required; basic swimming ability and comfort with a mask are sufficient, and guides provide briefings and equipment.
Tours may be canceled or rescheduled if authorities deem sea conditions unsafe; standard cancellation terms usually allow refunds if canceled 24 hours prior.
Samui Boat Charter operates guided outdoor trips and adventures with an emphasis on safety, stewardship, and memorable experiences.
