Ang Thong Marine Park: How to Plan Your Day from Koh Samui

If you’ve ever dreamed of turquoise lagoons, dramatic limestone cliffs, and hidden beaches, Ang Thong National Marine Park should be on your itinerary. Even if you haven’t been there, you might recognize it - part of the famous movie The Beach, directed by Danny Boyle and based on Alex Garland’s 1996 novel, was filmed in Ang Thong Marine Park and Phi Phi Islands. With 42 islands, 41 uninhabited, this protected archipelago is a must-see from Koh Samui.

What is Ang Thong Marine Park?

“Ang Thong” means Golden Bowl, and it’s easy to see why. The islands form a stunning, almost untouched natural landscape, making every visit unforgettable. The Ang Thong National Marine Park was established on 12th November 1980 and consists of the Mu Ko Ang Thong archipelago in the Gulf of Thailand.

Most of the islands are close together, creating a breathtaking panorama when sailing around the park. Ang Thong is a protected nature area, celebrated for its beauty, with all islands uninhabited and undeveloped, except for one.

Geologically, the islands are made of limestone mountains ranging from 10 to 400 meters above sea level. Over centuries, weather and chemical changes have sculpted the limestone into striking caves, cliffs, and formations, giving the archipelago its dramatic and otherworldly appearance.

Shared Tours vs Private Charters

When planning your visit, you’ll notice two main ways to experience Ang Thong: shared group tours or private charters.

Shared Group Tours

• Depart on a fixed schedule with designated stops.

• A few hours are usually allocated for swimming, snorkelling, or hiking at each island.

• Great for those who enjoy meeting fellow travellers and a structured day.

• More budget-friendly, but less flexibility in timing and stops.

Private Charters

• Flexible itinerary: choose where to go and how long to stay at each spot.

• A more personalised experience with fewer people around.

• Ideal for families, couples, or groups wanting control over pace and activities.

• Costs more than shared tours but offers a relaxed, customised experience.

  
  

Both options offer incredible experiences, the choice depends on whether you prefer a social adventure or a tailored escape.

Seasonal & Practical Considerations

Ang Thong Marine Park: How to Plan Your Day from Koh Samui: Ang Thong Marine Park is accessible most of the year, but the park is closed from 1 November to 15 December. This closure allows the park’s wildlife and natural environment to rest and recover, ensuring the islands, reefs, and marine life remain healthy and protected.

Expect crowds: Shared group tours will include other guests, which can make popular spots busier. Private charters offer more flexibility and privacy, letting you explore quieter areas and enjoy a more relaxed experience.

Weather matters: Always check local forecasts before heading out. It’s best to plan around good weather for safety and comfort.

Final Tips

• Realistic expectations: The park is stunning, but you won’t have it all to yourself -especially on popular group tours.

• Private charters can help you avoid the crowds and enjoy a more personal experience.

A trip to Ang Thong Marine Park is a must-do when visiting Koh Samui. Whether you’re hiking to emerald lakes, snorkelling over coral reefs, or simply relaxing on pristine beaches, this archipelago is a little piece of paradise waiting to be explored.
