Ang Thong National Marine Park Tourism

An exotic tropical paradise, situated in the Gulf of Thailand, Ang Thong National Marine Park is a protected archipelago of 42 islands. With unusually spectacular scenery, the Marine Park features Limestone Mountains, thick jungles, white-sand beaches, waterfalls, surreal lakes, unexplored caves and small hikes leading up to breathtaking viewpoints. The serenity of these islands is so captivating that one of the island’s lake – Lake Emerald – was featured in the movie ‘The Beach’ starring Leonardo Dicaprio.

The island is a protected area of more than 100 kms square where a variety of exotic species of mammals, sea creatures, birds, reptiles and trees reside. These islands will force you to get in touch with your adventurous side as there are numerous adventure activities offered by the Marine Park such as hiking, snorkeling, kayaking, diving etc. If you’re not an adventurous person, you can just choose to relax by the beach amidst all the tropical beauty and have an equally great time.

Emerald Lake
Emerald Lake

The Emerald Lagoon is situated in Ko Mae Ko (Mother Island) and is a must-visit. The Movie ‘The Beach’ was shot in this very same spot. It is in the middle of the island surrounded by Limestone cliffs and linked to the sea through an underground tunnel due to which it’s a salt lake. You can reach this spot after a climb of nearly 40 minutes. The climb is worth the panoramic view of the Park offered by the lake spot. However, swimming is not allowed in the lake.


There are a number of kayaking trails through the Marine Park which provides spectacular sights of the Park. You can stop your kayak on an island and enjoy the beaches.

Snorkelling is one of the many water-sports offered here. Some areas have clear shallow waters perfect for snorkelling. The coral reefs in the Park can be explored through snorkelling and scuba diving.

Camping gear and tents can be rented out from headquarters in Ko Wua Talap. Only certain designated spots are available for camping. Check with the authorities about them.

Ko Wua Talap

On the island of Ko Wua Talap, there is a 30-minute hike to a viewpoint proving the best view of the entire stretch of the island in the Gulf of Thailand. This is an iconic picture-perfect view and should not be missed.

  • There are no pets allowed in the Marine Park.
  • Touching the corals should be to a minimum.
  • Take all the rubbish back with you.
  • Remember to carry a lot of water and to carry a high SPF sunscreen.

Trips to the Ang Thong Marine Park are organized day trips from Koh Samui, Koh Phangan and Koh Tao. It is not possible to explore all 42 islands of the archipelago in one day, but you can manage to visit the most popular ones such as Ko Sam Sao, Ko Wua Talap and Koh Mae. There are no resorts here, but there are five bungalows set up on ko Wua Talap each accommodating between two to eight guests. Camping is allowed on certain grounds of the Marine Park. To keep the Marine Park from losing its authenticity due to extensive development, only a few selected licensed tour operators are allowed here. Only one of the 42 islands is inhabited by a sea-gypsy community who lead a traditional fishing lifestyle.
