Satun Geopark in southern Thailand has become the country’s first UNESCO Global Geopark.
The Geopark, known for its limestone mountain ranges, abundance of fossils and network of beautiful islands, was recognized for both its diverse geological and cultural heritage as well as efforts at the site to promote conservation, education and tourism best practices in a holistic manner.
The endorsement of this nomination was made during the 204th Session of UNESCO’s Executive Board in Paris. This inscription was recommended by the UNESCO Global Geoparks Council.

Satun Geopark covers four districts in Satun Province: Thung Wa, Manang, La-Ngu, and Amphoe Mueang.
As with all UNESCO Global Geoparks, the Satun Geopark has been granted the UNESCO status for a four year period (2018-2021), after which a re-validation process will take place.
Satun Geopark boasts a diverse abundance of fossils from the Paleozoic Era, as well as diversified Karst topography. There is evidence of a submerged landscape dating back more than 500 million years, a time when early organisms thrived, including trilobites, brachiopods, stromatolites, conodonts, graptolites, tentaculites and nautiloids.
The Geopark is also home to the largest cave in Thailand, Phu Pha Phet cave.
UNESCO Global Geoparks also celebrate humanity’s bonds to the land and the Satun Geopark is exemplary in this regard, as it is home to many ethnic groups with rich cultural traditions, such as the Maniq and Urak Lawoi.

Twenty million years separate the two rock groups that come into contact at the popular geological site of Khao To Ngai mountain: Cambrian sandstone from about 500 million years ago and Ordovician limestone from 480 million years ago. A footbridge runs on the side of the mountain along the seafront, marking the fault boundary. The site is popular for wedding ceremonies, with couples enjoying a walk along a footbridge that marks the fault between the two rock groups – a symbolic way to mark a “love that spans time”.
What are UNESCO Global Geoparks?
UNESCO Global Geoparks are single, unified geographical areas where sites and landscapes of international geological significance are managed with a holistic concept of protection, education and sustainable development. UNESCO Global Geoparks aim to enhance awareness and understanding of some of the most pressing challenges we face, such as environmental sustainability, climate change, and disaster risk reduction, by exploring our geological heritage and its connection with the area’s natural, intangible and cultural heritage.
