It's a very small beach but worthwhile to see for the amazing blue hues of the sea.
After the visit to Dragunara you can also take the boat from here to visit the nearby Grotte di Nettuno (Neptune's Caves) or take the car and go to the belvedere on top of Capo Caccia.
You can also snorkel along the coast.
It takes around 30 minutes by car to reach the beach. By bicycle it's around 22 km.
