Portisco lies half way between Porto Cervo and Porto Rotondo and at the feet of the spectacular mountains of San Pantaleo. One passes it on the way south to Olbia, four kilometres after Cala di Volpe.

This is a large apartment complex with an efficient and well-protected marina, a commercial centre and with only a few privileged villas right on the sea. Though it is surrounded by Costa Smeralda land, it does not actually form part of the Costa Smeralda Consortium. It is just across the water from Portorotondo.

It has very large common grounds and is close to one of the most beautiful beachs of the area, the Rena Bianca, with its white sand.
