Many islands in Satun have unique rock and stone formations, and the UNESCO Global Geopark is also located exclusively here.
Famously referred to as the ‘Land of Palaeozoic fossils’, Global Geopark is renowned for its abundance and high diversity of fossil species as well as for the oldest succession of fossils including trilobites, graptolites, tentaculites and nautiloids.
Prasat Hin Panyod is probably the most important geosite of the Geopark. The outstanding geological features of this site are characterised by a spectacular pinnacle karst landscape, including a stunning sea cave and hidden lagoon, which tourist can visit by kayak.
