Cala Violina
This pristine, beautiful beach in the Scarlino nature reserve takes its name from the tiny quartz grains of sand that sing like the strings of a violin when you walk along its shores. It's open to only 700 visitors a day during the season, and you can book your spot online. Arrive early to snag a spot in the parking area, which is a 1.6-km (1-mile) walk or bike ride from the beach. Amenities: food and drink; parking (fee); toilets. Best for: swimming; walking.
