Sardinia is surrounded by beautiful beaches, and in all honestly trying to say which are the best beaches is not an easy one...
Near Cagliari you will find an area called Villasimius , the Sardinia beaches in this area are really stunning.
Going further up the east coast you will encounter the Costa Rei. Stretches of fine white sandy beaches, the kind that sometimes does get on your nerves cause it sticks everywhere!
