We come across a wide variety of sea birds, amongst which are wild doves in the so-called “Grotta dei Colombi” (Wild Dove Cave), one of the first known settlements of the Gulf of Cagliari from prehistoric times.

Snorkeling Sella del diavolo

If you like snorkelling this half day excursion is just right for you. Come and discover the fascinating underwater world around the Sella del Diavolo (Devil’s Saddle) promontory in the centre of the Gulf of Cagliari.

Trekking on the Sella del Diavolo

The Sella del Diavolo promontory is a real naturalistic pearl set in the Gulf of Cagliari, just a few minutes from the city centre. The panorama is quite breathtaking and there are several points of great natural, archaeological and historical interest to be observed.

Nora and Pula a Plunge into the Blue

We anchor in the beautiful emerald green sea in front of the archaeological ruins of Nora where we can dive for a morning of snorkelling along the cliffs. Afterwards we can enjoy some moments of relaxation in front of the Capo Pula promontory.
