The Pubusinu spring is one of the largest in Sardinia. It has a flow rate of 220 liters/second and supplies the municipal aqueduct of Fluminimaggiore. The spring is located in the Pubusinu area, 6 km from the SS. 126 highway, and is served by a mining road passing through the Su Zurfuru and Gutturu Pala mines. Today, thanks to interventions by the Municipality and the Geomining Park, a municipal park has been established around the spring.
