The Bormida di Spigno is a river of north-west Italy. Its headwaters are in the Ligurian province of Savona above Pian dei Corsi at 1,000 metres (3,300 ft) above sea level in a transitional zone between the Alpine and Apennine mountain ranges. There its waters run as the separate “Bormidas” of Mallare and Pallare in distinct close valleys before quickly joining after a few kilometers.
