Greve river valley (Val di Greve) is located in central Tuscany. It rises in the Querciabella area, near Lamole. It flows east to the Montagliari plain (Piano di Montagliari) between Panzano-in-Chianti and Greve-in-Chianti. It then flows north below Calcinaia, Castello di Verrazzano and Castello Vicchiomaggio before entering a narrow gorge at Greti in Greve-in-Cianti.
