A full-day speedboat outing from Koh Samui that pairs snorkeling, a summit viewpoint and kayaking around the Emerald Lagoon. Fast transfers and guided stops make this an efficient way to experience Angthong’s limestone islands and clear water.

The hull slices a bright wake as Koh Samui falls away and the limestone islands of Angthong draw near. Salt spray pushes against the bow, the archipelago resolving from haze into sheer cliffs, white beaches, and the green bowl of Talay Nai — the famous Emerald Lagoon. On a clear morning the speedboat ride is part of the show: wind in your face, islands crowding the horizon.

The hull slices a bright wake as Koh Samui falls away and the limestone islands of Angthong draw near. Salt spray pushes against the bow, the archipelago resolving from haze into sheer cliffs, white beaches, and the green bowl of Talay Nai — the famous Emerald Lagoon. On a clear morning the speedboat ride is part of the show: wind in your face, islands crowding the horizon.
Angthong Marine Park, a protected cluster of roughly 42 islands created by coral, sand and uplifted limestone, was designated a national marine park to preserve its reefs, mangroves and inland lagoons. Local guides link geology to culture here: fishermen, coconut growers and small-boat operators have shaped travel and foraging patterns for generations. The Emerald Lagoon sits like a private sea within an island’s rim; kayaking its calm water and hiking the short, strewn-trail to the summit reveal panoramic arcs of turquoise and jagged karst.
Expect a day balanced between water and land — morning snorkeling over coral bommies, a Thai buffet lunch on the boat, a 20–40 minute climb to the viewpoint with roughly 100–200 m of ascent, then optional kayaking or beach time. The park charges an on-site fee (bring cash), conditions vary with the monsoon, and guides brief groups on reef-safe practices.
Practical edge: hydrate before departure, use reef-safe sunscreen, wear grippy water shoes for the beach-to-trail transition, and bring a light wind layer for the return run. The trip is an efficient way to see Angthong’s highlights in a single, high-energy day.
No — the national park admission is paid on arrival at the park (bring cash; current rates are typically around 300 THB for adults).
Expect a 20–40 minute climb on a steep, uneven trail with steps — it’s short but requires steady footing and moderate fitness.
Yes; snorkeling spots are suitable for first-timers with basic swimming ability and guides provide instruction; kayaking around the Emerald Lagoon is often optional and guided for safety.
Take preventive medication before departure, sit mid-boat for a smoother ride, focus on the horizon, and notify staff who can suggest calmer positions or shade.
MY Holiday Centre operates guided outdoor trips and adventures with an emphasis on safety, stewardship, and memorable experiences.
