The day begins at a private pier in Bophut with the engine humming and a salt-slick breeze pushing you away from Koh Samui. Insea Speedboat cuts a silver ribbon across the Gulf and, within an hour, islands rise from the water — sheer limestone cliffs, sheltered coves and a lagoon that seems to change color with every angle of light.

Ang Thong National Marine Park, established in 1980, is a 42-island archipelago shaped by uplifted limestone and coastal erosion. The geology creates dramatic cliffs, hidden beaches and the emerald lagoon in Mae Koh, while small communities on islands like Phaluai still fish and maintain sea‑gypsy traditions. The park is a living classroom where coral gardens and coastal forests share the same postcard.
Expect a mix of activities: off-boat snorkel stops in shallow bays, a brisk climb to Mae Koh’s viewpoint for panoramic frames, and a guided kayak along rocky shorelines. Guides hand out equipment and life jackets; lunch is a Thai-style buffet on Phaluai. Weather and sea conditions dictate the exact order, so flexibility is part of the plan.
Practical edge: the viewpoint involves uneven stone steps and 15–30 minutes of uphill walking in tropical heat, so bring sun protection, a dry bag and shoes that grip when wet. Hydrate before the hike — the sea will tempt you, but the sun will push back hard. Return to Koh Samui in the late afternoon with salt-damp clothes and clear images of limestone walls daring you to come back.

The Mae Koh viewpoint requires a 15–30 minute uphill walk on uneven steps; it’s short but can be strenuous in heat, so take water and pace yourself.
Children can join but infants must sit on an adult’s lap; snorkeling and kayaking depend on age and swimming ability — check with the operator for age-specific policies.
Ang Thong was declared a national marine park in 1980; the islands have long supported small fishing communities and seasonal use by seafaring groups.
