Selfoss is the largest town in South Iceland and an important service center for the surrounding agricultural communities. It stands on the Ölfusá River, whose broad waters are fed by the glacial rivers of Iceland’s southern highlands. The town is relatively modern in appearance, but its position beside the river has long made it an important crossing point and meeting place. Today, Selfoss combines shops, restaurants, museums, and public spaces with easy access to the surrounding countryside. Its location also makes it a convenient base for exploring the landscapes of South Iceland.

Selfoss developed around the Ölfusá River and the growth of agriculture and trade in the surrounding district. The Old Dairy, or Mjólkurbú Ölfusinga, is one of the town’s notable heritage buildings and now forms part of the Skyr House, which explores the history of skyr and Icelandic dairy production. The town is also associated with the poet and Nobel Prize winner Halldór Laxness, whose work is represented in regional cultural attractions. Selfoss’s modern center includes reconstructed and newly built streetscapes that reference traditional Icelandic architecture while providing space for local businesses and community events.

The Ölfusá River is the defining natural feature of Selfoss, flowing directly through the town and crossed by its prominent bridge. Nearby attractions include the geothermal area around Hveragerði, the volcanic landscape of Hengill, and the agricultural plains stretching toward the coast. Selfoss is also close to the route commonly known as the Golden Circle, giving access to Þingvellir National Park, the Geysir geothermal area, and Gullfoss waterfall. Within the town, the Selfosskirkja church and riverside paths provide quieter places to explore, while the surrounding countryside offers views toward mountains and distant glaciers.

Food is an important part of Selfoss’s identity, particularly through its connection with South Iceland’s farms and dairy producers. Skyr is one of the best-known Icelandic foods associated with the region, and the Skyr House presents its history alongside tastings and exhibits. Local restaurants make use of Icelandic ingredients including lamb, dairy products, fish, and seasonal vegetables. Selfoss is also home to Ölfusárbrú, the bridge across the Ölfusá, which has long been a key transport link in southern Iceland. The combination of river, farmland, and regional services gives the town a distinct role in the south.
