8 UNESCO World Heritage Sites in Thailand

Historic Town of Sukhothai and Associated Historic Towns (1991)

Located in northern Thailand, the Historic Town of Sukhothai and Associated Historic Towns were one of the first UNESCO-recognized heritage sites in Thailand. A trip to these UNESCO World Heritage Sites in Thailand is not for admiring the ancient beauty only, but also to gain a deep insight into the roots of Thai culture. 

The total property consists of 3 main towns, Sukhothai, Si Satchanalai, and Kamphaeng Phet. Sukhothai, also known as “the City of Happiness”, was the political and administrative capital of the first Kingdom of Siam in the 13th and 15th centuries. At the same time, Si Satchanalai served as an economic center, advantaging in the ceramic export industry, while Kamphaeng Phet held military functions to protect the kingdom. 

Sukhothai Historical Park

During its golden era, these historic towns in Thailand boasted their unique features in art and architecture, known as the “Sukhothai style”, which can be found in most of the fine monuments and monumental sculptures. 

Walking around the landmarks of Sukothai, such as Wat Si Chum or Wat Saphan Hin, is like traveling back to the once-glorious time of the ancient Siamese kingdom. You’ll see how the Sukhothai style reflects harmony, spirituality, and refined beauty, which later became the foundation of Thai art and culture.

Thungyai - Huai Kha Khaeng Wildlife Sanctuaries (1991)

Thungyai - Huai Kha Khaeng Wildlife Sanctuaries were the first UNESCO-recognized natural heritage site in Thailand. Tucked away in the Tenasserim mountain range along Thailand’s western border with Myanmar, the natural attraction covers more than 600,000 hectares, making up the largest conservation area in mainland Southeast Asia. 

Thanks to its limited access and the preservation efforts, these wildlife sanctuaries create a continuous natural corridor where wildlife can thrive. They are home to a very diverse array of fauna and flora, including endemic animals like Sino-Himalayan, Indo-Burmese, and Indo-Chinese affinities, and some rare plant species.

If you love to explore nature and animal behaviours in a natural setting, these places are absolutely for you. During the adventure, you’ll be taken care of by a knowledgeable and experienced guide, and have a rare sight of lively wildlife that you have barely ever seen. The giant footprints of large mammals, the lush jungle trails, the colorful birds perched high in the canopy - all await you in Thungyai - Huai Kha Khaeng Wildlife Sanctuaries.

Historic City of Ayutthaya (1991)

The Historic City of Ayutthaya was founded in 1350 and became the second Siamese capital after Sukhothai. Out of all the UNESCO World Heritage Sites in Thailand, this relic is the easiest one for tourists to reach. In its heyday, the ancient kingdom of Ayutthaya (1350-1767) was a regional powerhouse before falling to Burmese invaders. 

Now, you can explore ancient ruins that date back centuries and still capture the spirit of the once-glorious Ayutthaya Kingdom. Wat Mahathat, blending Khmer and traditional Buddhist architecture, is especially famous for the iconic Buddha head gently cradled by banyan roots. Nearby, Wat Phra Si Sanphet stands out with its three elegant chedis built in the Ceylonese (Sri Lankan) style, once serving as the royal temple within the Grand Palace grounds. 

Ayutthaya ruins reflect its heyday

Together with many other traces scattered across the site, these monuments reveal the cultural exchange, artistic sophistication, and religious devotion that defined Ayutthaya at its height. Walking among these ruins today, you’re stepping into the heart of a UNESCO World Heritage Site that tells the story of power, spirituality, and resilience over the centuries.

Ban Chiang Archaeological Site (1992)

Located 50 km from Udon Thani, a northeast province in Thailand, Ban Chiang is home to one of the most remarkable archaeological sites in Asia. The site preserves the prehistoric evidence of ceramics, bronze tools, remains, and traces of a 5000-year-old civilization. 

The first place that any tourist should head for after arriving in Ban Chiang is the Ban Chiang National Museum. Established on the foundation of the original archaeological site, the museum provides an engaging atmosphere to learn about life thousands of years ago.

You’ll observe a huge collection of dark red earthenware jars with signature patterns, labor tools, pottery shards, and animal bones. Along with the human remains preserved in their original burial positions, you can wrap up a historical period of 5000-year long within one glimpse.

Dong Phayayen - Khao Yai Forest Complex (2005)

Dong Phayayen - Khao Yai Forest Complex is the fifth among 8 UNESCO World Heritage Sites in Thailand. This vast natural site comprises 5 protected areas, which are Khao Yai, Thap Lan, Pang Sida, Ta Phraya National Parks, and Dong Yai Wildlife Sanctuary. 

Being the second largest protected forest complex in Thailand, this area spans over 230 km across six provinces in north-east Thailand and is home to hundreds of fauna and flora species, including 2 species of gibbon. Dong Phayayen - Khao Yai Forest Complex plays an important role in protecting the natural habitats and biodiversity, which makes it a crucial part of the UNESCO natural sites.

Kaeng Krachan Forest Complex (2021)

If you’re planning a trip to Hua Hin or Cha Am, don’t miss the chance to visit Kaeng Krachan, a nature reserve along the Thailand-Myanmar border in the west. Despite being the largest forest complex in Thailand, this area was recently recognized as a UNESCO World Heritage Site in 2021, after a long debate due to concerns about the indigenous rights. 

This site includes several protected areas, with the core site being the Kaeng Krachan National Park. It is well-known for its diverse landscapes with mixed forest types, dominated by semi-evergreen and moist evergreen forests. You can encounter some endemic and endangered animals here, such as the Asian elephant, Asian giant tortoise, Asiatic black bears, fishing cat, and clouded leopard.

The Ancient Town of Si Thep and its Associated Dvaravati Monuments (2023)

This is a serial property that encompasses 3 parts: a distinctive twin-tower site, the massive Khao Klang Nok monument, and the Khao Thamorrat Cave monument. These sites reflect the interchange of India’s and the Dvaravati Empire’s architecture, artistic traditions, and religious life during the 7th to 11th centuries.

Due to the flow of time, Si Thep Ancient Town is not completely intact. However, you can still observe remains of the once-thriving Dvaravati city at Si Thep Historical Park, a protected archaeological site 130 km to the south of Phetchabun Province. Here, you can still trace the outlines of the inner town and outer town, both encircled by ancient moats and earth walls.

Si Thep Historical Park 

The inner town, Muang Nai, was home to most of the sacred shrines and religious monuments, while the outer town, Muang Nok, served the residential purpose and agricultural activities. Walking around these spaces, you not only see scattered ruins and foundations, but also sense the scale of urban planning that connected religion, community, and nature more than a thousand years ago.

Just a short drive away, Khao Klang Nok and Khao Thamorrat Cave are 2 unmissable spots in your exploration of UNESCO World Heritage Sites in Thailand. The Khao Klang Nok is built of solid laterite blocks, while Khao Thamorrat Cave is based on a more intimate and natural setting, highlighting its ancient carvings. Both reflect the blending of Thai culture with broader Buddhist influences, which is a powerful reminder of how spirituality shaped the community during the Dvaravati era.

Phu Phrabat Historical Park (2024)

Phu Phrabat Historical Park became Thailand’s eighth UNESCO World Heritage site in July 2024. Located in the northeastern province of Udon Thani, the site is notable for its outstanding universal value, which is a testimony to the Sima stone tradition of the Dvaravati period (6th-11th centuries CE).

The Sima stones were used to place around the ordination halls of monasteries. It marked the sacred boundary where important Buddhist rituals were performed. Therefore, a vast number of Sima stones in Phu Phrabat Historical Park demonstrate the arrival of Buddhism, which then shaped the community life and contributed to the ingenious culture during the Dvaravati period.

Beyond the Sima stone tradition, Phu Phra Bat Historical Park is captivating for its majestic rocky landscapes. You can observe the unusual rock shelters and shrines, the archaeological traces of the ancient civilization, and numerous cave paintings vividly recreating the life of humans throughout history. More than simple stones, these markers are evidence of the cultural exchange in the early period, which explains the cultural and religious identity of Thailand today.
