The Fium'Alto rises to the south of the 1,767 metres (5,797 ft) Monte San Petrone in the commune of Pie d'Orezza.
It flows southeast past the village of Pie d'Orezza, east past Piedicroce and Stazzona, then generally north and east to the town of Folelli (Penta-di-Casinca) and the sea.
The D71 road follows the upper part of the river, and then the D506 follows it for the remainder of its course.[2]
