This shared big-boat trip runs from Koh Samui to Ang Thong National Marine Park, the 42 limestone islands north-west of Samui.

- Includes: pickup, buffet lunch on board, drinks, snorkel gear; kayaking with that option
- Excludes: national park fee (cash)
- Fitness: moderate, for the viewpoint climb
The Route
The crossing from Nathon takes about 75 minutes. On Koh Wua Talap, the park’s main island, a steep trail climbs past a series of viewpoints to the top, with the whole archipelago below. The round trip can take up to two hours, and you can stop at the lower viewpoints. There is also Bua Bok cave and time on the beach. After lunch on board, the boat moves to Koh Mae Ko, where a short climb leads to the platform over Thale Nai, the Emerald Lake.
Watch out: The national park usually closes for the monsoon from about 1 November to mid-December, with dates that shift with sea conditions. Check before booking a trip in that window.
Who It Suits
It suits families and anyone who gets seasick on speedboats: the big boat is slower but steadier. It is not a snorkelling trip, so pick the speedboat version if time in the water matters more.
Insider Tip: Take sports shoes, water and a small towel for the Wua Talap climb. It is short but steep, and the humidity makes it feel much longer.
