It crosses the communes of Muracciole, Noceta, Venaco and Vivario. The Vecchio rises to the north of the Punta dell'Oriente in the commune of Vivario. Its upper section is called the Ruisseau de Fulminato. It runs north or north-northeast through the Foret de Vizzavona past the village of Vizzavona to a point south of Santo-Pietro-di-Venaco where it turns to the east and flows to the Tavignano.

The viaduct over the Vecchio, or Eiffel bridge, in the commune of Vivario was built between 1891 and 1893 by Gustave Eiffel. It is a metal railway viaduct with three interdependent spans, running between abutments hollowed out by double arches and supported by two piers. The work was undertaken by the contractor Vignolle. The bridge was classified as a "Monument historique" on 29 July 1976. The viaduct runs above the old road bridge on a loop of  the RN 193 between Venaco and Vivario, built between 1826 and 1827. It was replaced by a new bridge in 1999 and is now only used by cyclists and pedestrians. The new bridge on the RN 193 is downstream from the old bridge, built between 1996 and 1999.
