The Ombrone's source is at San Gusmè, near Castelnuovo Berardenga, on the south-eastern side of the Monti del Chianti. After a twisting route, it receives the waters of the tributaries Arbia, Merse and Orcia before reaching the plain of Grosseto near Istia d'Ombrone.^[1]

It subsequently passes in the outskirts of the city of Grosseto, before flowing into the Tyrrhenian Sea.
