The beach is named after the 'giudeu' (octopus), reflecting the abundant marine life surrounding the islet.
The Stagno di Spartivento behind the beach is an Important Bird Area (IBA) due to its population of nesting and migrating waterbirds.
The sand dunes at Su Giudeu are among the highest in southern Sardinia, reaching heights of up to 20 meters.
The beach is a frequent filming location for Italian and international cinema due to its pristine, non-commercial appearance.
The water clarity is attributed to the low density of urbanization and the high circulation of currents around the promontory.
The island accessible during low tide is a geological formation of granite rock.
Su Giudeu Beach is a prominent stretch of coastline in Chia, defined by a distinct islet connected to the shore by a thin strip of golden sand. The beach is bordered by a protected saltwater pond, the Stagno di Spartivento, which serves as a seasonal habitat for colonies of greater flamingos. The landscape is characterized by high, shifting dunes covered in Mediterranean maquis vegetation and juniper trees. The seabed remains shallow for several meters, creating a large lagoon-like swimming area. It is part of the larger Chia coastal system known for its clear, turquoise waters and exposure to the Mistral wind. The beach features a rocky islet, reachable by foot during low tide, which provides a vantage point over the coastline. Natural erosion and dune protection measures are strictly enforced to preserve the habitat. The area is largely undeveloped, lacking permanent large-scale hotel structures directly on the sand.

Bring water shoes if you plan to climb the rocky islet, as the surface is uneven and can be sharp.
Visit during a low-wind day to ensure the water remains clear and calm for swimming.
Utilize the designated wooden walkways to cross the dunes to prevent environmental damage to the vegetation.
Do not attempt to walk through the cordoned-off dune restoration areas, as these are critical for coastal stabilization.
Removing sand, pebbles, or shells from the beach is prohibited by local law. Smoking is restricted in many areas of the beach to protect the ecosystem.
