Gardone sits just north of Salò on the western shore of Lake Garda. It is a small and rather charming place, quieter than the busier resort towns further north.
The main sight is the Vittoriale degli Italiani, the extravagant estate of the poet and nationalist Gabriele D'Annunzio. His house is jammed with all sorts of objects — beautiful individually, but taken together they create something like a sensory overload. In the gardens you will find an anti-submarine boat and parts of a warship, along with an open-air theatre with views over the lake.
The town itself has a pleasant lakeside promenade and a botanical garden (the Giardino Botanico Hruska) worth a visit if you are in the area.
