National Parks in Thailand, a Journey into Beauty

Dense rainforests, ancient valleys, exotic wildlife and enchanting underwater scenery: with its rich biodiversity, Thailand is a paradise for nature lovers. Last year, 17 million people visited its 154 protected areas, each with its own distinctive character, which are worth the trip. Here are eight, from north to south of the country.

Rising 2,565 metres above sea level, Doi Inthanon National Park in Chiang Mai province is the ‘roof of Thailand’, famous for its majestic peaks, waterfalls, evergreen forests and numerous scenic spots. Home to gorals, mountain goats that scurry along steep cliffs and narrow crevices, and more than 340 species of birds, the park is a birdwatcher’s paradise. It is open year-round, while the Kew Mae Pan trail, a 4km route through humid forests and mountain meadows, is only accessible from November to May.

Erawan National Park , in Kanchanaburi, covers 550 square kilometres along the Kwae Yai River and rainforest on Thailand’s western border. Erawan Falls, with seven cascades cascading into tranquil lagoons, make it the country’s top destination for outdoor swimming in the heart of tropical jungle. Well-maintained trails wind through lush forests and lead to mysterious caves, such as Tham Phra That, known for its shimmering limestone formations. The cooler months of November to February or the warmer months of March to May are ideal for visiting the park.

In the heart of Thailand lies the Khao Yai National Park , a UNESCO World Heritage Site, located in Nakhon Ratchasima Province. It boasts a reserve of natural wonders and numerous trails that lead to famous waterfalls such as Haew Narok and Haew Suwat; elephants, deer, bears, gibbons and a wide variety of bird species populate the area. Outdoor enthusiasts can indulge in trekking, bird watching and day and night nature safaris, along well-maintained trails with different levels of difficulty. In the surrounding area, there are also vineyards, golf courses, elegant lodges and glamping campsites.

Located 160km north of Phuket Island, Surat Thani’s Khao Sok National Park is home to one of the world’s oldest rainforests, dating back 160 million years. The park’s biodiversity is astonishing, with majestic limestone formations and dense canopies inhabited by macaques and gibbons. The park is home to 48 mammal species, 311 bird species, over 30 bat species and a myriad of reptiles and insects. At its heart is Cheow Lan Lake, a peaceful oasis surrounded by towering cliffs, making it an ideal spot for boat and kayak tours and floating resort stays. A commitment to sustainable tourism adds to the park’s appeal.

On the border with Laos, along the Mekong, lies Pha Taem National Park , in Ubon Ratchathani province. Famous for its cliffs overlooking the river and its ancient rock paintings dating back over 3,000 years, it is a perfect destination for nature and photography enthusiasts.

Among the marine parks , the Mu Ko Ang Thong one stands out, in the Surat Thani area: an archipelago of 42 islands covered in jungle, reachable in two hours by speedboat from Koh Samui. It offers postcard-perfect tropical landscapes: ivory beaches, lush vegetation and crystalline waters. The paths lead to spectacular views, such as the one from the top of Koh Mae Koh, which overlooks an emerald green salt lake nestled between the cliffs. The Laem Son National Park, which includes several islands in the Andaman Sea, such as Kang Kao and Kum, is particularly recommended in summer, from May to August. Among its beauties, the long white sand beach of Bang Baen, surrounded by a natural pine forest, and that of Lam Son, ideal for bird watching. The islands of Kam Yai and Kam Nui are also located there. Finally, the Mu Ko Similan National Park, in the province of Phang Nga, can be reached in an hour and a half from Khao Lak. Situated in the Andaman Sea, the fascinating marine park covers 128 square kilometers and comprises 11 islands, famous for their seascapes, rainforests, granite boulders and fine white sand beaches, protected by pristine coral formations.
