The municipality of Provaglio d’Iseo is situated in the valley of Monte Cognolo, close to the Torbiere del Sebino (peat bogs). Ancient finds discovered in the area have revealed the existence of human settlements since prehistoric times.
The old quarries, now turned into peat bogs, are an important natural and ecological site for the biodiversity of the local fauna and flora.
The Proai Golem, commonly known as the Guglielmo Marathon, is an annual sporting event with a 30 km route from Provaglio to Monte Guglielmo.
