It’s an opportunity for thrilling ecotourism, whether you’re trekking to a multi-tiered waterfall or kayaking through a hidden sea cave. So, pack your hiking boots and your sense of adventure, and prepare to discover the untamed soul of Thailand.
Top 12 National Parks in Thailand to Explore
This curated list will guide you through the diverse landscapes of Thailand, from the cool northern highlands to the tropical southern islands, showcasing the very best of the country’s protected wilderness.
The Mountainous North
The northern region of Thailand is defined by its rolling hills, cooler climate, and rich Lanna culture. Its national parks are havens of high-altitude flora, diverse birdlife, and breathtaking viewpoints.
Doi Inthanon National Park (Chiang Mai)
Often called “The Roof of Thailand,” Doi Inthanon is home to the country’s highest peak, soaring to 2,565 meters (8,415 feet) above sea level. The journey to the summit is an experience in itself, with the air growing cooler and the landscape transforming into a lush, temperate cloud forest.
Near the peak stand the magnificent Royal Twin Pagodas, Phra Mahathat Naphamethanidon and Naphapholphumisiri, built to honor the late King Bhumibol Adulyadej and Queen Sirikit. These elegant chedis, surrounded by beautiful flower gardens, offer stunning views of the valley below, especially when the morning mist rolls in.
The park is a world-renowned destination for birdwatching, with over 360 species recorded. For an unforgettable experience, take a walk along the Kew Mae Pan Nature Trail, a wooden boardwalk that winds through a moss-draped, fairytale-like forest.
Doi Suthep-Pui National Park (Chiang Mai)
Perhaps the most accessible national park in Thailand, Doi Suthep-Pui looms large over the city of Chiang Mai, making it a perfect and popular overnight trips.
The park’s most famous landmark is Wat Phra That Doi Suthep, a sacred temple with a glistening golden chedi that is one of northern Thailand’s most important religious sites. After climbing the 306-step Naga staircase, you are rewarded with intricate murals, tinkling bells, and a panoramic viewpoint overlooking the entire city. Further into the park, you can visit the Bhubing Palace, the royal family’s winter residence, with its impeccably manicured rose gardens.
The park also offers numerous hiking trails, waterfalls, and Hmong villages where you can learn about the local hill-tribe culture. Its blend of spiritual significance, royal history, and natural beauty makes Doi Suthep-Pui a quintessential Chiang Mai experience.

The Central Plains & Western Forests
This vast region is home to some of Thailand’s oldest and largest protected areas, forming a critical wildlife corridor that shelters some of the country’s most iconic species.
Khao Yai National Park (Nakhon Ratchasima)
As Thailand’s first national park and a UNESCO World Heritage Site, Khao Yai is a true national treasure. Spanning more than five distinct forest zones, this sprawling park is a biodiversity hotspot and one of the best places in Asia for wildlife encounters. It’s home to a thriving population of wild elephants, which are frequently spotted along the roadsides or at salt licks.
The haunting calls of gibbons echo through the trees at dawn, and magnificent great hornbills are a common sight. The park is also famous for its spectacular waterfalls, including the powerful Haew Narok and the iconic Haew Suwat, which was featured in the movie “The Beach.”
With an extensive network of trails, excellent visitor facilities, and popular night safaris that typically begin around 19:00, Khao Yai offers an immersive jungle experience just a few hours’ drive from Bangkok.
Erawan National Park (Kanchanaburi)
The undisputed jewel of Erawan National Park is its namesake waterfall, a stunning cascade that tumbles down seven tiers over 1,500 meters. Each tier has its own unique character, spilling into large, emerald-green pools that are simply irresistible for swimming. The crystal-clear water is filled with fish that will gently nibble at your feet.
A well-maintained hiking trail follows the falls, becoming progressively more challenging as you ascend to the top tier. The trek through the lush bamboo and deciduous forest is a rewarding adventure in itself. Located in the popular province of Kanchanaburi, Erawan is an idyllic escape where you can spend a full day hiking, swimming, and picnicking in a picture-perfect tropical setting.
Kaeng Krachan National Park (Phetchaburi)
As the largest national park in Thailand, Kaeng Krachan is a vast and rugged wilderness that forms part of a forest complex extending into Myanmar. Its sheer size and dense jungle make it a sanctuary for an incredible diversity of wildlife, though sightings can require patience.
The park is particularly famous among birdwatchers and butterfly enthusiasts, with hundreds of species recorded. The most sought-after experience here is witnessing the “sea of mist” from the Phanoen Thung viewpoint. Early in the morning, a thick blanket of clouds fills the valley below, with the peaks of distant mountains emerging like islands.
This magical spectacle, combined with the raw, untamed nature of the forest, makes Kaeng Krachan a top destination for serious nature lovers and photographers.
Kui Buri National Park (Prachuap Khiri Khan)
If your dream is to see wild Asian elephants in their natural habitat, look no further than Kui Buri National Park. This park has become the premier destination in Thailand for elephant watching, with a success rate of over 99% for sightings on guided safari-style tours.
Open-air vehicles take visitors to designated wildlife viewing areas where, in the late afternoon, large herds of elephants—often including babies—emerge from the forest to graze and socialize in the open grasslands. It’s a truly moving and unforgettable spectacle. The park is also a vital habitat for gaur (Indian bison), one of the largest bovine species in the world. Kui Buri’s conservation-focused approach provides a responsible and highly rewarding wildlife experience.
The Southern Rainforests & Coastal Wonders
Southern Thailand is where the jungle meets the sea, creating dramatic landscapes of ancient forests, towering limestone cliffs, and rich coastal ecosystems.
Khao Sok National Park (Surat Thani)
Khao Sok is a breathtaking realm of superlatives. It contains a rainforest that is over 160 million years old, making it one of the most ancient evergreen forests on Earth. The park’s centerpiece is the spectacular Cheow Lan Lake, an immense reservoir created by the Ratchaprapha Dam.
Here, hundreds of sheer limestone karsts rise vertically from the turquoise water, creating a landscape often compared to Guilin in China or Halong Bay in Vietnam. The best way to experience the lake is by staying overnight in one of the iconic floating raft houses (bungalows). From there, you can spend your days kayaking into hidden coves, trekking to caves, spotting wildlife like langurs and hornbills, and waking up to the symphony of the jungle. Khao Sok is a true adventure paradise.
Khao Sam Roi Yot National Park (Prachuap Khiri Khan)
Meaning “Mountain of Three Hundred Peaks,” Khao Sam Roi Yot is Thailand’s first coastal national park, masterfully combining dramatic mountain scenery with vital marine wetlands.
The park is famous for its series of towering limestone peaks that rise sharply from the coastline. It’s a critical area for migratory birds, making it a fantastic spot for birdwatching. However, the park’s most iconic attraction lies hidden inside a mountain. A steep but rewarding climb leads you to the magnificent Phraya Nakhon Cave. Within this massive, sunlit cavern sits the Kuha Karuhas Pavilion, a beautiful throne built for King Rama V. When the sun is directly overhead, typically between 10:00 and 11:30, light beams illuminate the pavilion, creating a scene of ethereal, almost mystical beauty.

World-Class Marine Parks (Andaman Sea & Gulf of Thailand)
Thailand’s marine parks are legendary, protecting some of the most vibrant and biodiverse underwater ecosystems on the planet, both in the Andaman Sea and the Gulf of Thailand.
Mu Ko Similan National Park
Consistently ranked among the top ten dive destinations in the world, the Similan Islands are an archipelago of up to 11 islands in the Andaman Sea. They are renowned for their gin-clear waters, offering visibility of up to 30 meters.
Below the surface lies a paradise of vibrant hard and soft coral reefs teeming with marine life, from tiny clownfish to majestic manta rays and whale sharks. Above the water, the islands are characterized by huge granite boulders, smoothed by the elements over millennia, that tumble down to meet pristine, white-powder sand beaches.
The park is only open from mid-October to mid-May to protect its fragile ecosystem during the monsoon season, making a visit here a truly special and sought-after experience.
Mu Ko Surin National Park
Located further north and closer to the Myanmar border, the Surin Islands offer a slightly wilder and more remote marine experience than the Similans.
This archipelago is considered one of the best snorkeling destinations in Thailand, with shallow, healthy reefs that are easily accessible from the shore. Sea turtles are abundant here, and it’s not uncommon to spot them grazing peacefully on seagrass.
For scuba divers, the park’s crown jewel is Richelieu Rock, a submerged pinnacle that acts as a magnet for big pelagics, including whale sharks. The park is also home to a village of Moken people, a community of “sea gypsies” who have traditionally lived a nomadic life on the water, adding a fascinating cultural dimension to any visit.
Ao Phang Nga National Park (Phang Nga)
Instantly recognizable from the 1974 James Bond film “The Man with the Golden Gun,” Ao Phang Nga National Park is famous for its incredible seascape of over 40 limestone islands and sheer karsts that rise dramatically from the calm, emerald-green waters of the bay. The most famous of these is Ko Tapu, or “James Bond Island.”
While speedboats full of tourists flock to the iconic islet, the best way to explore the bay’s true magic is by sea kayak. Paddling silently, you can navigate through a network of sea caves (hongs) and enter hidden lagoons in the center of the islands, discovering ecosystems that are only accessible during low tide. It’s a surreal and beautiful experience that showcases one of nature’s most spectacular geological wonders.
Mu Ko Ang Thong National Park (Surat Thani)
A stunning archipelago of 42 islands and islets, in the Gulf of Thailand, Mu Ko Ang Thong served as the inspiration for Alex Garland’s novel “The Beach.” This protected area is a compact wonderland of steep limestone mountains, thick jungle, white-sand beaches, and hidden coves.
The signature experience is hiking to the Wua Ta Lap viewpoint, a challenging climb that rewards you with a breathtaking panoramic vista of the entire island chain scattered across the azure sea. Another must-see is the hidden “Emerald Lagoon” (Thale Nai) on Ko Mae Ko, a saltwater lake in the middle of an island, connected to the sea by an underwater tunnel.
Easily accessible as a day trip from Koh Samui or Koh Phangan, Ang Thong offers a perfect blend of adventure and stunning scenery.
