Porto Istana
Porto Istana is a sheltered bay just outside Olbia where the water stays remarkably calm and clear, making it a go-to spot for families and anyone who wants a quieter stretch of Sardinian coast without the crowds of Costa Smeralda. The beach is fine white sand backed by low Mediterranean scrub, and the surrounding area has enough local bars and amenities to keep things comfortable without feeling overdeveloped. It's an easy base for exploring the Olbia coastline, with the open Gulf of Olbia right on your doorstep.
