Brightsun's Guide to Thailand’s National Parks

Beyond Thailand’s beaches lies a world of rainforests, wild elephants, limestone peaks, hidden caves and tropical islands waiting to be explored.

With more than 100 national parks, Thailand offers far more than beaches and busy cities. Its protected landscapes range from dense rainforests and dramatic limestone mountains to waterfalls, wetlands and tropical islands. Wildlife, hiking, kayaking and snorkelling are just some of the ways to explore these natural spaces. Here are some of the best national parks to add to a Thailand itinerary.

Khao Sok National Park

A Jungle Escape on Cheow Lan Lake

Khao Sok is one of Thailand’s most spectacular national parks, known for its ancient rainforest, turquoise waters and towering limestone cliffs. One of its most memorable experiences is staying at a floating camp on Cheow Lan Lake, where safari-style tents sit above the water.

The area is ideal for kayaking, jungle walks and wildlife spotting, with gibbons, birds and other rainforest species found throughout the park. A visit can also include time at an Elephant Hills camp, where rescued elephants are cared for in a natural setting.

Kui Buri National Park

One of Thailand’s Best Places for Wild Elephants

Kui Buri is one of the best places in Thailand to see elephants in their natural environment. The park protects a large population of wild elephants, which can often be spotted from designated wildlife-watching areas.

Safaris are conducted in open-top 4x4 vehicles with local guides and rangers. Along with elephants, visitors may also see gaur and golden jackals across the park’s forests and grasslands.

Khao Sam Roi Yot National Park

Limestone Peaks and a Hidden Cave

Meaning “mountain of 300 peaks,” Khao Sam Roi Yot is known for dramatic limestone mountains, wetlands and quiet beaches along Thailand’s eastern coast.
The highlight is Phraya Nakhon Cave, a vast natural cavern featuring the beautiful Kuha Kharuehat Pavilion. Visiting between around 10am and 11am offers the chance to see sunlight streaming through the cave’s open roof and illuminating the pavilion.

Khao Yai National Park

Rainforest Wildlife Close to Bangkok

Thailand’s first national park, Khao Yai is a favourite for wildlife enthusiasts. Its forests and grasslands are home to elephants, gibbons, macaques, hornbills, porcupines and many other species.

The park has numerous hiking trails, while guided night excursions offer opportunities to see nocturnal wildlife. One of its unusual attractions is the evening bat exodus, when millions of bats leave a cave in search of food.

Ang Thong National Marine Park

A Tropical Island Adventure

Made up of 42 limestone islands, Ang Thong National Marine Park sits in the Gulf of Thailand, around an hour by speedboat from Koh Samui or Koh Phangan.
The park is perfect for a day on the water, with opportunities for snorkelling, kayaking and exploring hidden coves and beaches. Ko Mae Ko is home to Tale Nai, an emerald-green saltwater lake surrounded by limestone cliffs and forest.

Doi Inthanon National Park

Thailand’s Highest Mountain

Known as the “Roof of Thailand,” Doi Inthanon reaches 2,565 metres and offers a cooler mountain climate than much of the country. Its forests are home to rare orchids, waterfalls and diverse birdlife.

The park is best explored through its walking trails, which pass waterfalls, bamboo bridges and dense cloud forest. The surrounding area is also home to Karen communities, where visitors can learn about local traditions and sample locally grown coffee.

Explore Thailand Beyond the Beaches

Thailand’s national parks offer a different side of the country, from ancient rainforests and dramatic mountains to quiet beaches, wildlife encounters and tropical islands.

With national parks spread across the country, it is easy to combine these natural escapes with Thailand’s cities, islands and beach destinations. So, when planning your next trip, set aside some time to venture into the wild and see a side of Thailand that is every bit as memorable.
