The speedboat cuts a white wake across glassy Gulf water, spray tasting faintly of salt and lime; limestone cliffs rise like sculpted towers and the islands hang green and sudden against a blue sky. By mid-morning the boat slips into a sheltered cove where masks click and fins whisper as snorkelers fan out over shallow reefs, while sea breezes push kayaks toward hidden beaches.

Ang Thong National Marine Park is an archipelago of 42 islands shaped by coral, reef and uplifted limestone; its karst cliffs and the inland “Emerald Lake” on Koh Mae Ko are the result of millions of years of reef growth and tectonic movement. The park was set aside to protect its mix of terrestrial jungle and rich marine habitats, and local fishing communities around Koh Samui long fished these same waters.
On this full-day speedboat routing expect snorkeling at Koh Wao, a lunch on board or shore, a short hike to the Talay Nai viewpoint (Emerald Lake), and time for kayaking and beach relaxation on Koh Wua Ta Lap. Trails are short but steep—stone steps and loose gravel are common; currents can be strong when exiting coves.
Practical pointers: book a morning departure to avoid afternoon swells, wear reef-safe sunscreen, and bring a light change of clothes and sturdy sandals for viewpoints. Guides provide snorkel gear, life vests and kayaks, but a well-fitting mask and reef shoes improve comfort. Respect no-take zones, avoid touching coral, and carry out any trash—these islands stay wild when visitors act like temporary guests.
The tour runs about eight hours and typically includes transfers from Koh Samui hotels, a buffet lunch, snorkeling gear, kayaks, life vests and an English-speaking guide.
Yes—snorkeling takes place in shallow bays with life vests and basic gear; guides monitor groups and point out safe areas.
Families are common; children should be comfortable in water and use life vests. Check operator age limits and supervision rules before booking.
