If you are driving from Cagliari to Alghero, or you're in the area, I recommend a stop at the Dune di Torre dei Corsari. Here you can experience the beauty of the island's rugged coastline.
The Dune di Torre dei Corsari is a stretch of sand dunes that rise up to 100 meters above sea level. If you walk up high enough, you get breathtaking views of the surrounding landscape. In addition to its natural beauty, the Dune di Torre dei Corsari is also home to the Torre dei Corsari, a medieval tower that was once used to defend the area from pirates, stands proudly on the beachfront.
Enjoy some fresh sea air while taking in the stunning scenery!
