In the heart of the Gulf of Thailand, and not far from Koh Samui, Koh Phangan and Koh Tao, is the Ang Thong National Marine Park (also known as Mu Ko Ang Thong), a group of 42 large and small islands comprising this protected archipelago. It is one of the most spectacular destinations in Thailand.

Ang Thong, translated as "Golden Bowl", received the nickname Golden Bowl of the Gulf of Thailand. The Ang Thong National Marine Park is offering some of the most magnificent landscapes in Thailand. Its landscape is often compared to that of Halong in Vietnam.

Declared a marine national park in 1980, Mu Ko Ang Thong National Park consists of 42 islets spread over an area of 102 square kilometers. Most of the islands are steep limestone hills. The highest point of the park is about 396 m above sea level. It is in the shallow water area near the shore with an average depth of 8-10 meters. The islands are uninhabited but it is possible to stay overnight on the main island of Koh Wua Talap.

With 42 islands to discover, it would take a couple of weeks to visit the entire park. Usually, any excursion takes you to visit several islands. The trip combines activities such as hiking, kayaking, snorkeling or simply enjoying sun on the fine sandy beaches and the sea.

Of all its islands, the largest and probably the most famous is Koh Wua Talap. The island of Wua Talap is located in the bay of Kha. It is the main island of the park where the headquarters of the national park and the tourist information center are located. In front of the office, there is a beautiful white sand beach with crystal clear water where you can relax in the sun and swim.

You can go up to the viewpoint on the top of the mountain. You will see one of the most spectacular views in Thailand from there. It takes about 1 hour of walking to reach the top and this magnificent view. The summit is reached after a climb of some difficulty but the effort is really worth it. From it you can admire the impressive landscape of Ang Thong archipelago that is stretching in a long line of strange shapes, surrounded by the emerald sea. Koh Wua Talap also has a restaurant, camping, bungalows, caves, and some trails through the jungle.

Koh Mae Ko is also a must to visit at Ang Thong National Marine Park. Koh Mae Ko, known as Mother Island, has an emerald-colored saltwater lake, surrounded by limestone cliffs. The Emerald Lagoon, called Thale Nai, is connected to the sea by an underground tunnel. On the island, there is a small trek that takes you to a viewpoint with stunning panoramic views of the lake below and the surrounding islands. There is a natural stone bridge that arches out into the sea. Koh Mae Ko also has a fantastic white sandy beach suitable for camping and swimming.

Koh Pee Island is one of the best attractions of the marine park and is highly recommended due to its unique beauty. Normally, the boats stop here for tourists to spend some time swimming or to discover its small caves by kayak.

A must-do activity of the visit to the park is snorkeling at least at one of the 42 islands in Ang Thong Marine Park. You can search for colorful tropical fish swimming around the multicolored corals.

The activity will last about 40-45 minutes and it will not be necessary to go far to enjoy this experience. Many tours are not including this activity in the price but you should opt for kayaking.

Hiking at Koh Wua Talab Island is an experience not to be missed. There is a 500-meter-long steep path leading up the side of the rocks to take you to the viewpoint with spectacular view. You just need to make sure to have a good footwear as there are sharp limestone on the way.

When visiting Ang Thong National Marine Park, the tour will let you swim at the oceanfront. You can also lie down on the warm beach for sunbathing.
