Lake Garda, in northern Italy, is known for its crystal clear water. At the south end, the town of Sirmione is dominated by the Rocca Scaligera, a fortress with harbor views. The nearby Grotte di Catullo archaeological site includes a Roman villa. On the lake’s western shore, in Gardone Riviera, is Il Vittoriale degli Italiani, former home of poet d’Annunzio. The Dolomites frame Riva del Garda, a resort in the north.
The water quality at Lake Garda is tested on a regular basis. The guidelines for water quality in Italy are more stringent than in the rest of the EU. That way they can secure a very good and constant water quality at the beaches at Lake Garda.
