Beautiful beach with white sand and emerald water surrounded by mountains. It's relatively quiet (we went in mid September, so could be different in July - August though), so we had a relaxing time. There is a big car park nearby, so it is easy to access. The car park seems to charge €8 for a car in the high...
Believe all the reviews this place should be in the top 10 beaches in Sardinia.
Despite the lengthy drive up an unmade road the trip is so worth it!
If you walk 500 metres either way on reaching the beach you can be assured of a bit of a solitude as there are numerous little inlets and secluded spots.
