Capo CacciaThe sea preserve Porto Conte – Isola Piana is a wonderful natural park on the coast on the north of Alghero between Marina di Lioneddu and Capo Galera.
You can enjoy an extraordinary view from the sea: cliffs plunging into a deep blue sea just where the Harbour of Porto Conte starts. Opposite the promontory you can find the isle Piana and the isle Foredada, that is “pierced” from one side to the other by a cave excavated by the sea.
In the area it is possible to observe the flora and the fauna, to dive, to take photos, to practise bird watching, trekking, speleology and to visit archaeological sites.
The enormous calcareous massifs lodge a lot of air and sea caves. The most famous one on the surface above sea-level is the Grotta di Nettuno, which can be visited by sea or by earth means of transport. The submerged Grotta di Nereo is considered the largest submerged sea cave of the Mediterranean Sea and of Europe.
The bottom of the sea is inhabited by the coral red, poseidonies, dentex, sea-eels, sea-urchins, shellfishes and molluscs.
The vegetation is characterized by the Mediterranean bush and animal species threatened with extinction such as the wandering hawk and the griffin, which has become the symbol of the peninsula of Capo Caccia, may be observed.
The sea preserve has been entrusted to the Municipality of Alghero.


La Grotta di Nettuno

It is located under the spur of Capo Caccia and can be reached by walking through the stairs Escala del Cabirol (the Roe deer’s Stairs), a sort of panoramic stairs of 656 steps. Grotta di NettunoIt is also possible to arrive by landing at the entrance of the cave.

La Baia di Porto Conte

The gulf of Porto Conte, called by the Romans “the port f the nymphs” thanks to its limpid waters, is one of the most beautiful coasts of Sardinia: in addition to the tourist settlements, there are still inaccessible territories with an important environmental heritage. In particular, we would like to recommend the Foresta Demaniale Porto with its ponies of Giara, fallow deers and donkeys.

Capo Caccia

Capo Caccia can be admired from the sea and reached by car along the coast road from Alghero. The rocky spur can be reached by a three hours excursion starting from Tramariglio.
The name "Capo Caccia" probably comes from the hunting beatings because of the high number of rock-doves which inhabited it.
Capo Caccia is 168 metres high and lodges a lot of flooded caves, while the signs of the human presence dating back to twelve thousand years ago increase the beauty of the place.

Punta Giglio

Punta GiglioIt is a calcareous promontory with cliffs which may reach a height of 116 metres. On the eastern side it closes the bay of Porto Conte, while on its top it is possible to admire the surrounding territory.
Its name reminds the presence of wild lilies. The place is characterised by spectacular white cliffs, that were formed by the erosion of the sea waves, and by an inside area full of shrubs and bushes, which are so typical of the Mediterranean climate.
During the Second World War, Punta Giglio was an important anti-aircraft base. Some important signs of it, such as the positioning platforms for the anti-aircraft cannons and the explosive depots, are still visible today.

Villa di Sant'Imbenia

It is an ancient roman villa of the imperial period, probably dating back to the I-II centuries. A.D., which is nowadays in ruins. The boundary is large and it is possible to observe the ruins of a mosaic worn out by the sea. The villa is about 20 kilometres from Alghero. Not very far from it you can find the roman necropolis of Sant'Imbenia, the graves of which date back to the imperial period.

Nuraghe di Palmavera

Along the coast road between Alghero and Porto Conte you can visit the Nuraghe Palmavera dating back to the XIII century b. C. The building is formed by two towers surrounded by a defensive wall and by a village of about 50 circular huts. For more information about the guided visits, please contact the cooperative S.I.L.T.
