The sources of the era are on the territory of the municipality Volterra springing Era Viva (spring in the forest of Volpaie at Pignano, length 7 km) and Era Morta (Source at Sant'Anastasio and Spicchiaiola, length 6 km). After the confluence, the Era runs in a north-westerly direction through a valley within the hilly landscape of Colline Pisane and flows into the Arno at Pontedera at 10 m above sea level from the left. The catchment area of the Era is called Alto Valdera , while Valdera (Val d'Era) refers to a larger area that also includes communities north of the Arno.
