Bosa is a small town on the west coast of Sardinia, in the Province of Oristano, set along the Temo river in the Oristanese-Sinis area. It is known for its pastel-coloured houses climbing towards a medieval castle, and for the historic Sa Costa quarter with its narrow lanes. The town sits close to the coastline, giving it a mix of riverside and seaside character typical of this part of western Sardinia.
As a destination, Bosa draws visitors interested in authentic Sardinian town life rather than large-scale tourism, with its old tanneries, fishing heritage and nearby beaches contributing to its character. It remains a useful base for exploring the Oristano coastline and the surrounding countryside.
