A trip to Florence and also to Volterra was nice. Massa Marittima is definitely worth a visit. For a day at the beach, we can recommend the Torre Mozza beach. Parking fees apply, but the beach is very clean, as is the water, and the waves are only mild, since a sunken Roman road keeps the waves out. Therefore, the place is also good for snorkeling. Another beautiful beach can be found further north at Baratti. We felt it was worth the drive.
