Spiaggia del Principe - Poltu di li cogghj

Widely regarded as the most beautiful beach on the Costa Smeralda, Spiaggia del Principe — or Poltu di Li Cogghj locally — sits in a stunning cove near Arzachena, north of Olbia, in Sardinia. You anchor off and swim in, as there's no beach club or infrastructure here, just raw, unspoiled turquoise water and white sand backed by granite rocks and Mediterranean scrub. Bring your own umbrella and everything else you need.
