The speedboat cuts across the Gulf of Thailand and the island silhouettes sharpen: sheer limestone cliffs rise like stacked plates, lagoons glimmer inland, and the sea pushes cool, briny air over the deck.

The speedboat cuts across the Gulf of Thailand and the island silhouettes sharpen: sheer limestone cliffs rise like stacked plates, lagoons glimmer inland, and the sea pushes cool, briny air over the deck.
Angthong National Park is an archipelago of 42 islands carved from Miocene limestone and coral limestone, with sheltered coves, hidden caves and a famous emerald lagoon (Talay Nai) on Ko Mae Koh. The park’s history moves from local fishing grounds to protected marine reserve—today it balances tourism with conservation and local livelihoods.
On a full-day excursion from Koh Samui you’ll alternate short boat hops with snorkeling over patch reefs, guided swims among parrotfish and butterflyfish, and gentle kayaking through sea-carved channels. Expect boardings at a pier on Samui, a brisk ride by high-speed craft, and multi-stop exploration that includes beach time and a midday lunch aboard or on a beach.
Practical notes: bring reef-safe sunscreen, a lightweight long-sleeve for sun and wind, and anti-nausea medicine if you’re sensitive to chop. Snorkel equipment is usually provided and guides will brief beginners; kayaks are single- or double-seat and suited to calm lagoons. Respect closures and marine-protection signage—avoid touching coral and take all trash back to the boat.
This trip delivers concentrated marine scenery and active water time in one long day; it’s best for travelers who want a full, guided taste of Thailand’s coastal geology, clear water, and small-island ecology without the logistics of self-planned island hopping.

Angthong has long been used by local fishermen; the park was designated as a national marine park to protect its karst islands and coral habitats.
The park enforces no‑take zones and limits visitor numbers at sensitive sites—follow guides’ instructions and never take shells or coral to minimize impact.
