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.

In addition to other local foods, L'Ortolano has delicious local wines 😋 You can bring empty drinking bottles and the owner will be happy to fill you with the wine of your choice. Cheers 🍷

Like many lakes in Sardinia, it is an artificial basin created by the damming of the Coghinas river. To cross it there is a bridge but at the moment it is closed to traffic.

In Badesi there is delicious ice cream from 12 noon, right next to a nice greengrocer, a little further to the right a caseficio where you can buy good ricotta. The road is shaded in the morning and not too steep. In Viddalba you can have a delicious coffee in the bar.

Very quiet road with a good surface winding through small towns in the foothills. Beautiful views out to the coast and in to the mountainous interior. Interesting mix of flora along the way. Gentle slopes, gradual descent from northwest to southeast.

Romanesque church from the middle of the 11th century, freshly restored with EU funds. Like the much larger Romanesque church of Porto Torres, this one does not have a steeple either.
