Great view of the rocky landscape of Isola Rossa and the beaches 😊. If you come by bike, you should definitely note that you can't just roll down the beautiful descent, as there are always speed bumps installed. Some caution is required here - also because of the narrow paths and the traffic.

Castelsardo is considered one of the most beautiful villages in Italy. It is located on the Anglona promontory and at the top of the town stands the medieval fortress. A walk to explore the alleys is recommended.

Castelsardo is a fascinating medieval village. Visiting the historic center under the fortress is certainly worth it, even if the climb up the stairs can be a bit tiring. The town, traditionally fishermen, is known for the art of basket weaving. From here you can enjoy a beautiful view of the hamlet at the top of the hill in the distance.
