The Arroscia is a larger torrent river in the northern Italian region of Liguria . It is about 38 kilometers long and flows through the provinces of Imperia and Savona . The source of the Arroscia is on the Passo della Guardia , in the Ligurian Alps . From the spring, which is over 2000 meters high, it flows in a river bed that is partly deeply dug into the Ligurian plain and forms a picturesque waterfall near Mendatica .
At Pieve di Teco , the Arroscia receives the tributary of the Arrogna on the left and the Giara di Rezzo on the right . This is also where the valley of the same name, through which it has previously flowed, opens, and after the Borghetto d'Arroscia river has crossed it enters the province of Savona.
At the height of Villanova d'Albenga , the Arroscia reaches the Ligurian plain and increases its own water volume again through the right tributary of the Lerrone . Once in the plain, the river's gravel bed widens considerably. Near the town of Albenga , the Arroscia eventually merges with the Neva to form the Centa River .
Like the Centa, the Arroscia is marked by enormous amounts of water after heavy rains (mainly in autumn). In the summer months, however, as is characteristic of torrente, it is largely dried out.
