Ombrone
The Ombrone is a river situated in the provinces of Grosseto and Siena, central Italy.
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.
It subsequently passes in the outskirts of the city of Grosseto, before flowing into the Tyrrhenian Sea.
