It is enclosed and protected by two large cliffs that slope towards the limpid sea with colours ranging from emerald green and blue to turquoise, awarded in 2017-18 with the Blue Flag of the Fee (Foundation for Environmental Education), for environmental sustainability. The beach of Porto Palmas is a small and enchanting crescent-shaped stretch of medium-grained sand, soft, light and amber-coloured, mixed with white pebbles, a remnant of the nearby quarrying activities. It is located on the Nurra coast in the town of Palmadula, within the territory of Sassari, just north of the Riviera del Corallo and next to the mining settlement abandoned in the 1960s and the ghost village of Argentiera, fascinating scenario of industrial archaeology.
