The speedboat cuts through a jade-green sea and the first pinnacles of Angthong appear—dark limestone teeth rising out of the water, each island a private skyline. Salt spray and bird calls fill the air as you approach Wua Ta Lap, where a sandy shore and a steep stairway lead up to a viewpoint that looks over 42 ragged isles.

The speedboat cuts through a jade-green sea and the first pinnacles of Angthong appear—dark limestone teeth rising out of the water, each island a private skyline.

Angthong National Marine Park was declared in 1980 to protect this archipelago of karst islands and shallow coral plates in the Gulf of Thailand. The islands are limestone outcrops shaped by coastal erosion; freshwater sinks like Talay Nai (the "Blue Lagoon") collect rain and create unexpected emerald pools. Local fishing communities and Thai guides have long used these channels; today the park balances visitor access with protected marine zones.
Expect a mix of short hikes, beach stops, snorkeling in shallow coral gardens, and seated kayaking between limestone cliffs. The hike to the viewpoint is stair-heavy and steep in places, but rewards you with a panoramic sweep across the cluster. Snorkeling spots near Wua Ta Lab are shallow and good for spotting parrotfish, butterflyfish and soft corals.
Practical notes: tours run 7–8 hours with hotel transfers from main Koh Samui resorts; national park fees are usually cash-only. Bring reef-safe sunscreen, water, waterproof phone case and a light dry change. Time your trip for morning departures to avoid midday heat and choppier seas—watch for cancellations in rough weather. Follow guides’ instructions for marine safety and reef-friendly behavior to help keep the park healthy for the next visitor.
