Perched on a dramatic promontory overlooking the Gulf of Asinara, Castelsardo is one of the most picturesque villages in Italy and a true jewel of North Sardinia. With its medieval castle, pastel-colored houses, artisan traditions, and crystal-clear waters, Castelsardo offers an authentic Sardinian experience far from the crowds of the Costa Smeralda.
If you are planning a tailor-made journey to Sardinia, here is your complete guide to what to see and what to do in Castelsardo.
Where Is Castelsardo?
Castelsardo is located in northern Sardinia, about one hour from Alghero Airport and approximately 30 minutes from Porto Torres. Overlooking the Gulf of Asinara, the village enjoys breathtaking sea views and unforgettable sunsets.
Unlike many coastal destinations, Castelsardo perfectly combines beach life, history, culture, and gastronomy in one compact, walkable town — making it an ideal stop on a North Sardinia itinerary.
1. Explore the Historic Center (Centro Storico)
The heart of Castelsardo is its beautifully preserved medieval old town. A maze of narrow stone streets climbs up to the castle at the top of the hill.
What makes it special:
-
Flower-filled balconies
-
Artisan workshops
-
Stunning panoramic terraces
-
Authentic local atmosphere
Take your time wandering without a map. Every corner reveals postcard-perfect views of the sea and the surrounding coastline.
Insider tip: Visit late in the afternoon, when the golden light transforms the village into warm shades of pink and orange.
2. Visit the Castello dei Doria
Built in the 12th century by the powerful Doria family from Genoa, the Castello dei Doria dominates the skyline of Castelsardo and is the town’s most iconic landmark.
Today, the castle houses the Museum of Mediterranean Weaving, dedicated to the island’s ancient basket-making traditions — a craft still alive in the village.
Why you should visit:
-
Panoramic 360° views over the Gulf of Asinara
-
Insight into Sardinian craftsmanship
-
A journey through medieval history
The climb to the top is rewarded with one of the most spectacular views in North Sardinia.
3. Discover the Roccia dell’Elefante (Elephant Rock)
Just a few minutes outside Castelsardo, along the road toward Sedini, you’ll find one of Sardinia’s most curious natural landmarks: Roccia dell’Elefante.
This large trachyte rock formation resembles an elephant and hides something even more fascinating inside — prehistoric tombs known as Domus de Janas, carved directly into the stone thousands of years ago.
It’s a quick stop, but one that connects you to Sardinia’s ancient pre-Nuragic past.
4. Relax on the Beaches of Castelsardo
While Castelsardo is famous for its history, it also offers beautiful beaches.
The most popular is Lu Bagnu, a long sandy stretch just outside the town center, ideal for swimming and relaxing. The water is clear and calm, making it perfect for families.
If you prefer something more secluded, explore smaller coves along the coast toward Valledoria, where the sea displays every shade of turquoise.
5. Experience Sardinian Traditions and Festivals
Castelsardo is deeply rooted in tradition.
One of the most important religious events is the Holy Week procession known locally as Lunissanti. During this ancient ritual, members of the confraternity walk through the village chanting in Latin and Sardinian — a moving and authentic cultural experience.
Local artisans also preserve the art of basket weaving, using techniques passed down for generations. Visiting small workshops in the old town offers a glimpse into a living tradition that defines the identity of Castelsardo.
6. Taste Authentic Northern Sardinian Cuisine
A visit to Castelsardo would not be complete without savoring its gastronomy.
Typical dishes to try:
-
Zuppa gallurese (a traditional baked bread and cheese dish)
-
Fresh seafood from the Gulf
-
Bottarga (cured fish roe)
-
Sardinian pecorino cheese
-
Cannonau wine
Many restaurants offer terraces overlooking the sea — ideal for a romantic dinner at sunset, accompanied by local wines and the scent of Mediterranean herbs carried by the sea breeze.
7. Take a Boat Tour in the Gulf of Asinara
For a more exclusive experience, consider a private boat excursion along the coast. From Castelsardo, you can explore hidden coves, swim in crystal-clear waters, and admire the rugged northern Sardinian coastline from a different perspective.
A luxury boat day allows you to discover Sardinia away from the crowds — combining relaxation, privacy, and unforgettable scenery.

Spring and early autumn are ideal for travelers seeking authenticity, comfort, and a more intimate connection with the destination.
