The leafy headland of Punta San Vigilio curls out into the lake 3km north of Garda. An avenue of cypress trees leads from the car park towards a gorgeous crescent of bay backed by olive groves. There the Parco Baia delle Sirene offers sun loungers beneath the trees; there's also a children's play area.
Entry is free at sunset. Alternatively, from the parking place walk north a short distance and head off down the paths to a couple of smaller, quieter public coves.
