Lake Iseo is the fourth largest lake in Lombardy, Italy, fed by the Oglio river. It is in the north of the country in the Val Camonica area, near the cities of Brescia and Bergamo. The lake is almost equally divided between the Provinces of Bergamo and Brescia. Northern Italy is renowned for its heavily industrialised towns and in between there are several stunning lakes. Lake Iseo remains one of outstanding natural beauty, with its lush green mountains surrounding the crystal clear lake.
