Satun is a quiet harbour town in Thailand's deep south, on the Andaman Sea coast about two hours from Hat Yai and close to the Malaysian border. Most travellers pass through rather than stay — it is the departure point for boats to the Tarutao National Marine Park and Ko Lipe — but the town itself is pleasant enough, with a largely Muslim population and a distinctly Malay feel. The Satun National Museum occupies a fine Sino-Portuguese mansion and documents the area's mixed Thai-Malay culture.
The surrounding Satun province has several natural attractions. The Satun Geopark — a UNESCO Global Geopark since 2018 — contains Cambrian fossil beds and the limestone karst formations that are the geological backdrop to the province. Thale Ban National Park covers rainforest along the Malaysian border with gibbons and hornbills and is almost entirely tourist-free. The International Fishing Competition for the Tarutao Andaman Fishing Cup takes place every March, and the local Rotee Festival in January celebrates the area's signature flatbread.
