Selfoss, a town situated by the bridge of the river Ölfusá. In 1891 a bridge, which used to be the biggest construction in Iceland, was built across Ölfusá, after which the town began to grow. A new bridge was built in 1945. Selfoss is the largest town in South Iceland and the main service centre of trade and industry.
At Svarfhóll, on the outskirt of Selfoss, there is an attractive 9 hole golf course on the bank of the Ölfusá river. Furthermore the town has an outdoor and an indoor swimming pool with steam bath and hot tubs.
The National Circular Highway no. 1 leads through the town. Many scheduled trips go from Selfoss to, for example, Gullfoss waterfall and Geysir and to the wilderness of Þórsmörk. North of Selfoss is Hellisskógur with nice hiking paths by the Ölfusá river and a view over the golf course.
