Corsica’s marine nature reserves

The Cap Corse and Agriate Marine Nature Park covers an area of 6,830 km². Established in 2016, it encompasses the Cap Corse Islands Nature Reserve and part of an exclusive economic zone. The noble pen shell (Pinna nobilis), the giant limpet (Patella ferruginea) and the diadem sea urchin (Centrostephanus longispinus) are among its protected species.

To the south, the Bouches de Bonifacio nature reserve covers 80,000 hectares between Corsica and Sardinia. The area protects the Lavezzi archipelago , the cliffs of Bonifacio and various sea caves such as the Sdragonato. According to the official inventory, 37% of the Mediterranean’s notable species find refuge there.

Both areas fall within the boundaries of the Pelagos Sanctuary. This international area of 87,500 km², established by a tripartite agreement in 1999, protects eight species of cetaceans, including the common dolphin, the striped dolphin and the fin whale.

Scuba diving: an adventure in the depths of Corsica

Beginners can explore the wreck of the Pinella near Portivechju (Porto-Vecchio). The 42-metre cement carrier has lain at a depth of 11 metres since it sank in 1965. The Îlot du Toro in the Cerbicales Marine Reserve also offers accessible dives where schools of barracuda can be seen.

Level 2 divers enjoy the wreck of the B17 off Calvi . The American bomber has lain at a depth of 27 metres since February 1944. Its 31-metre-wide structure is now home to scorpionfish, moray eels and various benthic species.

Experienced divers explore Mérouville near the Lavezzi Islands. The site, known for its colony of groupers weighing up to 30 kg, lies at depths of 20 to 32 metres. The Cathédrales in the Gulf of Propriano feature drop-offs ranging from 15 to 55 metres, covered in sponges and gorgonians.

Kayaking and stand-up paddleboarding: gliding across the water’s surface for a better view

Cap Corse is home to coves that are accessible only to paddlers. From Saint-Florent, enthusiasts can paddle along the western coast of the Agriate peninsula, covering 225 km of coastline. The area is home to four underwater canyons (Centuri Nord, Centuri Sud, San Fiurenzu, Isula Rossa) and two fishing reserves established by ministerial decree in 1983.

In the Bouches de Bunifaziu (Bonifacio), kayaking allows you to explore the Lavezzi archipelago away from the tourist crowds, which number 150,000 visitors a year. The granite islets serve as a refuge for the common shearwater, a protected breeding species. The site is also home to the Mediterranean shag.

Snorkelling: an activity suitable for everyone

The Scandola Nature Reserve reveals its treasures to snorkellers. The red volcanic rocks create a striking contrast with the deep blue of the sea. However, regulations prohibit spearfishing, the collection of marine species and any form of removal of flora or fauna.

The Saint-Florent barrier reef is an exceptional coral formation. Protected by a prefectural decree since May 1998, the site prohibits all boat traffic, anchoring, spearfishing and the collection of marine plant species. This strict protection preserves a marine habitat of great biological richness.

The beaches of Palombaggia offer snorkelling spots suitable for families. Among the blocks of pink granite, the Posidonia seagrass beds are home to sars, wrasses, damselfish and, occasionally, curious octopuses. These underwater meadows form a vital link in the coastal ecosystem.

Preserving what we love to explore

Posidonia seagrass beds are a priority habitat in need of protection. The French Environmental Code prohibits their destruction or damage under Article L411-1¹, including their removal and the alteration of their environment.

Encounters with cetaceans require a respectful attitude. The Ministerial Decree of 1 July 2011 prohibits any pursuit, harassment or intentional disturbance. The Pelagos Sanctuary recommends keeping a distance of at least 100 metres from these animals and limits observation to 30 minutes.

Conventional sun creams are harmful to marine life. Opt for mineral-based versions that do not contain chemical filters such as oxybenzone or octinoxate to protect the health of both corals and fish.

When anchoring boats, choose sandy seabeds where possible. Seagrass beds, like coral reefs, suffer lasting damage from the mechanical impact of anchors. In some developed bays, eco-friendly buoys allow mooring without harming sensitive seabeds.

Diving in crystal-clear waters offers a unique encounter with marine life. Kayaking along the wild coastline allows you to explore inaccessible nooks and crannies. Meanwhile, snorkelling in a protected cove is ideal for curious families. Each of these activities creates a precious connection with this unique natural heritage that must be preserved.
