The beaches are used by the residents of local campsites and the Happy Village Hotel, there are no parking for tourists. During the season, it is possible to park for a fee at the campsite (N 40 00.093 E 15 21.460) and get access to the beach of Capogrosso. From there you can go to the beach of Cala dArconte, see the trails here.
During low season there is no parking at all. We left the car here N 40 00.471 E 15 21.130 (street view) and went down towards the sea. When you reach the gate, turn right, there is an asphalt path to the beach of Cala dArconte (street view).
