The adjacent Stagno di Notteri is a crucial nesting and feeding habitat for the Greater Flamingo (Phoenicopterus roseus).
The beach is part of the Capo Carbonara Marine Protected Area, established to preserve the rich marine biodiversity of the southern Sardinian coast.
The water clarity is significantly influenced by the local marine currents circulating between the nearby islands of Cavoli and Serpentara.
Despite its popularity, the beach maintains a natural dune system that acts as a protective barrier between the lagoon and the sea.
Spiaggia di Simius is a prominent white-sand beach located in the Marine Protected Area of Capo Carbonara in Villasimius, Sardinia. The coastline is defined by fine quartz-like sand and shallow turquoise waters that remain calm due to its sheltered position. Adjacent to the beach lies the Stagno di Notteri, a brackish lagoon frequently inhabited by colonies of pink flamingos. The beach stretches approximately one kilometer, offering both free-access areas and private bathing facilities. The seabed consists of sandy patches interspersed with rocky outcrops popular for snorkeling. Its orientation provides protection from the Mistral wind, keeping the water conditions generally stable.
The elevated path between the beach and the Stagno di Notteri provides a panoramic view capturing both the blue sea and the pink-hued lagoon.
Bring a snorkel and mask to explore the rocky points at the ends of the beach where marine life is most concentrated.
Walk toward the Stagno di Notteri during late afternoon for the highest probability of spotting flamingos.
Utilize the designated wooden walkways to reach the shore to prevent erosion of the protected dune ecosystem.
Do not attempt to walk through the restricted nature reserve areas near the lagoon; stay on marked paths to avoid disturbing wildlife.
The beach is most active and serviced during the summer season; off-season access is possible, but beach facilities are typically dismantled.
Removing sand, shells, or stones from the beach is strictly prohibited by regional law; use rinsing stations to clean gear.
