Visit Lake Iseo
Lake Iseo (Lago d'Iseo) is in the heart of the Lombardy region, north-west of Brescia.
The lake is rather over-developed at its northern end, so it is to the south you should head for the town of Iseo and the other small villages en-route, and for access to the lake-island at Monte Isola.
Iseo is a pleasant town for exploring the lake and surroundings - including the waterlily beds to the south of the town. Numerous lake and valley walks are also possible.
The island of Monte Isola is the largest island-lake in Europe, and almost car free - the island is still small enough to explore by bike or on foot. The walk / ride around the island offers very good views across the lake to the villages and mountains beyond (15 km total).
One interesting nearby attraction is the curious rock-pinnacle formations found at Cislano, above Marone.
