Thailand’s 10 Most Spectacular National Parks

1. Ang Thong National Marine Park

One of Koh Samui's best-kept treasures is an archipelago known collectively as Ang Thong National Marine Park. Made up of 42 islands, it's nestled in the Gulf of Thailand, near Surat Thani, and offers just about every natural wonder one can imagine. From hidden beaches to lush jungles, this park promises true immersion in nature for all types of adventurers.

For diving enthusiasts, Ang Thong is a must-see destination. The archipelago is home to exceptional marine biodiversity with various coral reefs and marine species. Each island group has unique surprises in store, giving you a unique diving experience at each stop.

One of the most fascinating aspects of Ang Thong is the diversity of its forest formations. You'll find evergreen forests on the larger islands, while rainforests line the beaches near the high-water mark. On some islands, you'll discover limestone forests that are home to a variety of vegetation, including morinda and euphorbia. In addition, in the sheltered areas of the archipelago, you can explore the mysterious mangrove forests by kayak, especially on the island of Mae Koh, east of Phaluai.

The star attraction of the archipelago, located on the island of Koh Mae Ko, is the Emerald Lagoon. It is said that it was once a limestone cavern several hundred feet high, which eroded into a seawater lagoon, surrounded by limestone cliffs and connected to the sea by an underground tunnel. This site is simply stunning.

Listed as a UNESCO World Heritage Site, it is a protected nature reserve and one of the largest in Thailand. Its biodiversity is staggering, home to elephants, black bears, gibbons, and a variety of birds, with a rare chance of spotting a tiger.

An ideal choice for trekking enthusiasts, Khao Yai National Park offers many hiking trails of varying levels of difficulty. Many of the shorter trails can be ridden independently, with clear markings and maps available at the Information Centre. However, if you are planning a longer hike in the heart of the jungle, it is recommended that you be accompanied by a professional guide who knows the area, both for your safety and to preserve the natural environment.

While many hiking trails pass through dense forests, offering thick foliage all around you, several walkable viewpoints offer panoramic views of the park. The park is also dotted with waterfalls, the largest of which is Haew Narok, a three-tiered waterfall that pours its waters 150 meters, creating an impressive waterfall and forming numerous pools below.

To get to Khao Yai National Park, you can take a car or bus ride of about three hours from Bangkok. Another option is to take a bus to Pak Chong, located in Nakhon Ratchasima province, where you will find the main entrance to the national park as well as many tourist amenities.

6. Mu Ko Surin National Park
