Santa Teresa Gallura (marina di Longonsardo)

Tucked into the northern tip of Sardinia, the marina at Santa Teresa Gallura sits right beneath the 16th-century Torre di Longonsardo, giving the anchorage a history-soaked backdrop you won't find at most ports. The town has a genuinely salt-in-the-air, working maritime feel — not overly polished — with good access to supplies, restaurants, and ferries crossing to Bonifacio in Corsica just a few kilometers away. The strait between Sardinia and Corsica makes for some of the most dramatic sailing waters in the Mediterranean, so this is a natural base for exploring both islands.
