The town of Bosa lies on the Temo river. The ancient part of the city is on the slopes of Mount Serravalle, on top of which is the medieval Malaspina castle.
The beach of Bosa Marina is very wide and characterized by fine gray-gilded dark sand. The great Spanish tower that overlooks it gives the sea resort an evocative charm.
