Medieval Sardinian headland town climbing to a Doria castle above the Gulf of Asinara.
Castelsardo is a small medieval town on a dramatic headland in the northwest of Sardinia, about 30 km northeast of Sassari. The old town climbs steeply up to a castle built by the Doria family in the 12th century, and the walk around the castle walls to the Cathedral of Sant'Antonio Abate is one of the best short urban walks on the island — views across the Gulf of Asinara are exceptional.
The town is famous for basket weaving. Walking through the narrow lanes of the old town, you'll often find local women sitting on their doorsteps, working on the distinctive woven baskets and bags made from dwarf palm and asphodel. The castle houses a small museum dedicated to this craft.
Below the old centre, the newer town has good restaurants and a small beach. More extensive beaches are at Lu Bagnu, just a couple of minutes by car.
The most famous event is the Lunissanti, a procession held during Holy Week that ends with a torchlight parade through the old town on Easter Monday evening — genuinely atmospheric and worth timing a visit around.

Beaches
The main beach near Castelsardo is at Lu Bagnu, just a few minutes by car west of the old town along the coast road. It is a long, sandy stretch with calm water and a small tourist development of bars and beach rental operations — nothing exceptional by Sardinian standards, but good for a swim and convenient to the town. Lu Bagnu can also be reached on foot from the lower part of Castelsardo in about twenty minutes.
The coast extends westward toward Valledoria at the mouth of the Coghinas River, where there is a longer and less developed beach. Eastward, the coast toward Portobello di Gallura has rocky coves that are best accessed by boat.

When to Go
Castelsardo is busiest in July and August when it draws beach visitors from across Sardinia and the Italian mainland. The old town gets crowded, parking is difficult, and accommodation is expensive. May, June, and September are much more pleasant — warm enough for swimming, quiet enough to walk the castle lanes in peace.
Lunissanti is the town's most atmospheric annual event: a Holy Week procession held over the three days before Easter. Hooded penitents carry sacred images through the narrow streets of the old town, ending with a torchlight procession on Easter Sunday evening. The event draws visitors from across the Anglona region and is genuinely affecting — the combination of the medieval setting, the darkness, the candlelight, and the old religious music makes for an experience unlike any other in Sardinia. If you can time a visit to coincide with Holy Week, do.
