Sinis beaches
Mari Ermi: guide to the Sinis quartz beach.
Two and a half kilometres of pale quartz, dunes and blue sea.
Mari Ermi is a long quartz beach in the Cabras area, backed by dunes and a coastal lagoon. Mal di Ventre island is visible offshore, one of the Marine Protected Area’s most distinctive landmarks.
Why choose Mari Ermi
The long beach makes it easier to find quieter areas even in busy periods. The sand mixes white and pink quartz, while the sea takes on vivid colours on clear days.
Nature and landscape
The lagoon behind the beach hosts waterbirds, including occasional flamingos. Dunes and coastal vegetation are fragile, so use established access paths and avoid protected areas.
Who it’s for
Mari Ermi is popular with families, couples and nature-minded travellers. Sea conditions can change with the wind, so choose the bathing area based on conditions on the day.
