Lake Garda, the largest among Italian lakes, can offer also visit in the close medieval castles and the thematic fun park Gardaland. If you get here you will be between Venice and Milan. Lake Maggiore is located north of Milan and west of Lake Como deep into Switzerland. Created by a glacier, it is surrounded by hills in the south and mountains in the north with 3 lovely islands in the centre.
Lake Bolsena is instead between Rome and Tuscany, deep in the crater of an extinct volcano, overlooked by a medieval centre with a fortress at the top.
