In recent years Arzachena has become a very popular destination for summer holidays but not only, since in addition to the beautiful beaches, this area has a lot more to offer such as trekking and food and wine routes, (certainly less tiring) .

The writer advises snorkelers not to forget the equipment as the marine flora and fauna of these places deserve to be absolutely discovered.
