THE ADVENTURE COLLECTIVE® · Independent discovery and booking for outdoor travel

Read the full experience

You step off a speedboat into warm, stirred water and the limestone islands of Angthong rise like weathered fortresses, jungle-streaked faces dropping straight into blue. 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.

History

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.

Adventure tips

Arrive early for clearer waterMorning departures usually mean calmer seas and better visibility for snorkeling and photos.

Bring reef‑safe sunscreenThe park is ecologically sensitive—use reef‑safe sunscreen to protect coral and marine life.

Wear water shoesBeaches and approach landings can be rocky; grip and foot protection make scrambling to viewpoints easier.

Secure valuables in a dry bagSpeedboat rides and wet landings can soak loose items—store phones and passports in a waterproof case.

Recommended gear

Reef‑safe sunscreen: Protects skin and coral during extended sun exposure on deck and in shallow snorkeling areas.
Water shoes: Provide traction on rocky beaches and help with short hikes to viewpoints.
Light dry bag (10–20L): Keeps phone, camera, and spare clothes dry during boat transfers and landings.
Personal snorkel mask (optional): Often more comfortable and better fitting than rental masks, improving your snorkeling experience.
