The sea dares you to swim, and the islands—42 in the park—invite you to paddle between hidden coves and climb rocky ridgelines for a view that unrolls toward the horizon.

Angthong was declared a marine national park in 1980 to protect limestone islands and marine habitats; the islands have long been used by local fishers and, historically, small communities seasonally visiting for resources.
Conservation
The park limits development and regulates tours to protect coral, seagrass beds and nesting birds—follow guides, don’t touch coral, and use reef‑safe products.
