Yes. Isola Rossa sits almost exactly between two other coastal highlights: Castelsardo, 30 km (19 miles) away with its clifftop medieval old town, and Costa Paradiso, about 18 km (11 miles) away with dramatic granite coves. Santa Teresa Gallura is a bit further at 48 km (30 miles). A private day trip lets you string two or three of these together in one route instead of picking just one.
Isola Rossa sits on the northern Gallura coast, around 80 km (50 miles) from Olbia and its airport, and about 85 km (53 miles) from Porto Cervo and the Costa Smeralda resorts. There's no direct train, and public buses run on a limited schedule, so a private transfer gets you there directly, door to door, without transfers or waiting around.
Half a day covers the watchtower, the old fishing quarter, and a swim at Marinedda beach. Give it a full morning to afternoon if you also want to swim at Cala Sarraina or take a short boat trip along the red granite coastline.
Isola Rossa's two main beaches, Marinedda and Cala Sarraina, both carry Blue Flag status for water quality. Marinedda opens onto a wide bay of fine golden sand and turquoise water framed by red cliffs, while Cala Sarraina is smaller and quieter. Both are well suited to swimming and snorkeling without needing to book anything in advance.
Start at the Torre Aragonese, a Spanish watchtower built in 1595 overlooking the harbor. Walk the seafront promenade to Marinedda beach, framed by the same red granite cliffs that give the village its name, then wander the old fishing quarter and the small church of the Santissima Trinità. It's an easy, walkable village to explore in a few hours.
Isola Rossa is a small fishing-village-turned-resort on Sardinia's Gallura coast, named for the rust-red granite island guarding its harbor. In just a few hours you get Blue Flag beaches, a 16th-century Spanish watchtower, and a working harbor lined with seafood restaurants, without the crowds of the bigger Costa Smeralda resorts nearby.
