We based in Sirmione at the extreme southern point of the lake. Sirmione is the site of a medieval castle and town with narrow, winding streets and a classic 'kur' house. A drive around the lake can be done in a day including stops in several of its lakeside towns. Each seems to have a lakeside promenade or plaza filled with museums, shopping, dining, and more castles and churches. The lake is filled with windsurfers flying about. Winter sports, including skiing, are available at the northeast point of the lake and theme parks for kids are at the southeast end. Buy local olive oil by the bottle or case! You'll not be able to walk by the gelato shops, either.
