The Frigidolfo (also called Oglio Frigidolfo) is a stream of Val Camonica, in the province of Brescia, about 7 km long.
It rises in the Valle delle Messi, near the Gavia Pass on the slopes of the Corno dei Tre Signori (3360 m a.s.l.).[1]
Along its path it receives water from the Arcanello.[2]
Its confluence with the Narcanello in Ponte di Legno (1300 m a.s.l.) gives rise to the Oglio River.[1]
