This beach is a great place to see a cross-section of Bari, and also get some sunbathing in. I don't recommend going in the water because it's fairly close to some sewer runoff holes, but the sand is nice, and there are showers to cool off with if you get too hot. Also if you prefer, there's a large lawn-like area where you can stay on the grass, instead of on the sand, so you don't have to worry about getting off the sand afterwards.
There's a great little coffee shop where you can get ice cream, coffee, and sandwiches, and just cool off in the shade.
This beach was created a few years ago in order to give the poorer Baresi a place to go during the summer; Bari is a seaside town, but it didn't have a "beach" with sand! Now you can find all kinds of people from Bari here...
It's great to go during the winter, too, as the coffeeshop is made entirely of glass so you can sit inside and look at the sea without having to feel the cold of the wind.
