You step off the pier in Koh Samui as the speed boat cuts a low wake toward a scattering of karst islands—sheer limestone cliffs rising from the Gulf, birds complaining at the edges, and the sea itself urging you forward.

You step off the pier in Koh Samui as the speed boat cuts a low wake toward a scattering of karst islands—sheer limestone cliffs rising from the Gulf, birds complaining at the edges, and the sea itself urging you forward.
The route threads through 42 islands that make up Ang Thong National Marine Park, moving fast enough to feel like travel and slow enough to study each rock face. Koh Wao drops you into clear water for snorkeling among coral gardens; Koh Mae Koh requires a short, steep climb of carved steps to reach the viewpoint above Talay Nai (the Emerald Lagoon), where a glassy saltwater pool reflects sunlight in startling green. The park’s limestone geology and collapsed caverns created the lagoons and sea tunnels you’ll paddle through by kayak, each cave shaping light and sound differently.
Locals have long used these isles for small-scale fishing and seasonal shelter; today the park is managed to balance day trips with conservation. Expect basic Thai buffet lunch on Koh Wua Ta Lub, changing rooms, and staff-led safety briefings before water activities.
Practical guidance: the full excursion runs about 8 hours—plan for sun, spray, and a moderate amount of walking and stairs. Bring reef-safe sunscreen, a light waterproof layer, and footwear that can get wet. If you’re prone to seasickness, take precautions before boarding; the Gulf is usually calm in the high season but can roll in monsoon months. Respect marked no-take zones, keep a hand off coral, and follow guides when entering caves or paddling tight channels.
