More ways to explore the area's outdoor wonders
A speedboat cuts a clean wake across the Gulf of Thailand and the islands of Mu Ko Ang Thong slide into view—limestone cliffs rising like rough-hewn towers from warm turquoise water. Salt spray and sunlight set the rhythm as you approach the park’s scattered islets; gulls call, and the urge to step off the deck and into the water is immediate.

Mu Ko Ang Thong was declared a national marine park to protect its karst islands, mangroves and coral reefs, preserving traditional fishing zones while allowing regulated tourism.
Conservation
The park enforces no-anchor zones, limits on visitor numbers at certain sites and encourages reef-safe sunscreens to reduce coral damage.
