At the heart of the Gulf dell'Asinara rises the promontory of Castelsardo, with its medieval town. The long beaches of this part of the North are beautiful and little frequented.
In addition to the port of Castelsardo north-east are the port Isola Rossa that provides an additional safety navigation in this part of the coast without natural shelter.
A few miles from Corsica these two ports can be a nice step for those who sail in these water or point of departure for the crossing to the French island.
