Capo Caccia Isola Piana Marine Protected Area
The ArchiMete Sardegna tourist center is located in the heart of the Capo Caccia–Isola Piana Marine Protected Area, a natural area established in 2002 to preserve one of the most spectacular marine ecosystems in the Mediterranean. This stretch of coastline is renowned for its extraordinary concentration of underwater caves, once a refuge for the rare Mediterranean monk seal.
These are spectacular environments, rich in marine life and easily explored by divers accompanied by experienced local guides, who lead visitors through inlets, tunnels and fascinating underwater landscapes.
The marine area also includes the evocative natural fjord of Porto Conte and extends along the coast from Punta delle Gessiere to the Capo Caccia promontory, passing through Punta Giglio. The landscape is dominated by imposing limestone cliffs overlooking the sea, an ideal habitat for numerous species of seabirds such as the Corsican gull, the cormorant and the majestic griffon vulture, a raptor that can reach nearly three meters in wingspan.
The protected area is divided into three zones with different levels of protection: Zone A, a fully protected reserve where all activities are prohibited; Zones B and C, where transit, scuba diving, snorkeling and, with specific permits, certain fishing activities are allowed. The establishment of the reserve marked a fundamental turning point for the protection and regeneration of the marine environment, allowing local biodiversity to recover and thrive.
Marine Fauna
The seabed of the marine area hosts an extraordinary biological heritage. The unique geomorphological features of the limestone cliffs favor the presence of sponges, lithophagous mollusks and beautiful gorgonians such as Paramuricea clavata and species of the genus Eunicella, which color the underwater walls with spectacular shades of red and purple. These waters are also home to the precious Corallium rubrum, the famous Mediterranean red coral, visible just a few meters below the surface inside many caves. This resource represents not only an ecological indicator of great value, but also a historic artisanal tradition for nearby Alghero, where coral has been crafted for centuries and is even depicted on the city’s coat of arms.
During dives, it is easy to encounter numerous species of crustaceans such as the Mediterranean spiny lobster, the European lobster, the slipper lobster and the spider crab, as well as the lively Parapandalus narval. In the seagrass meadows of Posidonia oceanica, you can observe seahorses of the genus Hippocampus, large shells of Pinna nobilis, cuttlefish and many bottom-dwelling fish. In open waters, it is not uncommon to spot pelagic species such as seabream, sea bass, dentex, groupers, barracudas, conger eels and even the curious ocean sunfish. The waters of Porto Conte and the cliffs of Capo Caccia are also frequented by cetaceans such as dolphins and Risso’s dolphins, often visible in the early hours of the morning.
The high coastal cliffs provide shelter for numerous seabirds, including the European shag, the Cory’s shearwater, the Mediterranean shearwater and the small storm petrel.
Flora and Landscape
The terrestrial area falls within the protected Porto Conte Regional Natural Park and is characterized by rich Mediterranean vegetation: fragrant maquis with mastic trees, myrtle and juniper alternates with evocative forests of Quercus ilex, often overlooking the sea. Beneath the surface, the seabed hosts numerous species of brown and green algae, while wide sandy areas are dominated by seagrass meadows of Posidonia oceanica. In the coastal stretches closest to the shore, algae belonging to the genera Caulerpa and Cymodocea thrive, contributing to the richness and balance of this extraordinary marine ecosystem.
