Why go
A go-to choice for anyone visiting southern Sardinia: a recognised natural setting, distinctive sea colours and the classic Sardinian beach-day experience, best enjoyed when the daily conditions cooperate.
Wind & sea exposure
Relatively sheltered from the Maestrale, so the bay often stays swimmable when other coasts are rough. Conditions still depend strongly on wind and sea state.
Family suitability
Whether the beach feels family-friendly varies by day — check wind, sea state and access before travelling with children.
Parking & access
Parking can vary by season — plan to arrive early in July and August and check for any local restrictions before leaving.
Best time to visit
The best days are usually those with calm seas and no sustained Maestrale. Early morning and late afternoon are the most comfortable windows in summer, while June and September often hit the sweet spot of temperature, crowds and conditions.
