Bue Marino

You anchor off this stretch of Sardinia's rugged east coast, right next to the Grotta del Bue Marino — a spectacular karst sea cave stretching over a kilometre into the cliffs, named after the Mediterranean Monk Seal that once sheltered here. The setting is wild and dramatic, with limestone formations carved by centuries of water meeting stone. The cave is open to tours for around €10 per person, making this anchorage a genuine destination rather than just a place to drop the hook.
