If you want to hit the beach on Sardinia, you might want to consider "Is Arutas". The beach near Cabras that is also known as the "Beach of the Grains of Rice". In contrast to many other beaches on the island, Is Arutas is entirely made from small pieces of quartz, giving it a white appearance with the occasional hue of pink and green. The beach stretches as far as the eye can see (it is several kilometers long) and does not seem to be too crowded. Likely has to do with the lack of big resorts in the area, wonder when that is going to happen.
