The beach's 'sand' is formed from eroded quartz crystals from the nearby island of Mal di Ventre.
Removal of the quartz grains is strictly prohibited by law, and violators face significant fines to preserve the beach's composition.
The Sale Porcus pond nearby is one of the most important wetlands in the Mediterranean for migratory birds.
The quartz granules do not stick to the skin like silica sand, making it easier to clean off after swimming.
Spiaggia di Mari Ermi is distinguished by its unique quartz sand composed of tiny, smoothed, multi-colored pebbles rather than traditional silica grains. It is located on the western coast of Sardinia within the Sinis Peninsula, bordering the protected Marine Protected Area of Penisola del Sinis - Isola di Mal di Ventre. The beach features a backdrop of dunes and the Sale Porcus pond system, which serves as a habitat for pink flamingos. The water is exceptionally clear due to the lack of fine sand sediment, often displaying turquoise and deep blue hues. The beach is exposed to the mistral wind, making it a destination for windsurfers and kitesurfers. Visitors can view the small island of Mal di Ventre directly offshore. The shoreline is expansive, allowing for significant distance between visitors even during high season.

Bring a mat or beach towel as the small quartz pebbles can be uncomfortable to sit on directly.
Pack wind-resistant gear, as the mistral wind can pick up suddenly on this section of the coast.
Wear water shoes if you have sensitive feet, as the pebbles can feel sharp during entry into the water.
Do not attempt to collect 'souvenir' jars of the quartz sand, as local authorities monitor beach exits.
Access is unrestricted, but parking facilities operate primarily during the spring and summer months.
Strictly prohibited to remove any quartz grains or pebbles from the beach; shower off at designated stations to prevent sand removal.
