Lake Garda, also called Lake Benaco, is the largest Italian lake. From glacial origin, the southern basin is divided into two gulfs separated by the thin peninsula of Sirmione and the northern one has an elongated shape which narrows at the extremity and is closed in by high and rocky banks. It has a varied landscape mixing beaches and olive-yards with the mountain tops of the alpine landscape. D.H. Lawrence defined Lake Garda "a beautiful lake just as in the beginning of Creation". The side of the lake in the Province of Brescia (59 km from Sirmione to Limone) has two distinct parts: the Brescia Riviera, from Salo' towards the north, is characterised by thermal spas, villas, hotels and parks one after another. Here, the Gardersana West, one of the most famous European roads mostly going through the mountainous rocks, offers one spectacular scenario after another. The other side, the one from Sirmione to Salo', is more of a plains area with only some low hills. The mild climate of the area favoured human settlements starting in the ancient era and the Romans were the first to begin the tradition, which continues on to the present, of building villas looking over the lake. Among the most prestigious historic heritage found in the area, the Sirmione Castle has to be mentioned. This Castle rises from the waters and defines the access to the medieval village. There are four islands in Lake Garda, the largest called Garda or Borghese is situated in front of the Portese point. The smaller islands are Olivo, Trimelone and San Biagio. San Biagio is the only Italian island that can be reached on foot.
