Monte Alfeo (1.651 m.) is one of the most beautiful and imposing mountains in the Apennine around Piacenza, in the Municipality of Ottone. It stands on the left side of Trebbia valley, between Boreca valley to the north and Dorbera valley to the south.
On the northern side, steep and covered in wood, there are small villages under the Municipality of Ottone: Belnome, Tartago, Pizzonero and Suzzi. On the southern side, where the village of Bertone stands (under Ottone Municipality as well), the flora covers the side of the mountain until 1,500 m before leaving room to ample meadows around the top, marked by a statue of the Virgin Mary.
