Descend into a natural amphitheatre in the Strait of Bonifacio where brown groupers (Epinephelus marginatus) gather in numbers you won't see elsewhere in the Mediterranean.
Citta Delle Cernie is a seamount nestled within the protected marine area of the Lavezzi Islands, right in the Strait of Bonifacio. This site isn't about dramatic walls or wrecks; it's a broad, rocky reef formation often described as a natural amphitheatre. The topography provides numerous crevices and overhangs, creating a complex habitat where marine life congregates, and divers can explore without the feeling of being confined.
As you descend onto the seamount, the true character of Citta Delle Cernie, or 'City of Groupers', becomes immediately clear. This site is world-renowned for its dense population of brown groupers (Epinephelus marginatus). These are not shy, elusive fish; years of protection within the marine park have made them unusually habituated to divers, often approaching closely without hesitation. You’ll find them resting in rocky shelters, cruising over the reef, and interacting with the environment.
Beyond the groupers, the rocky reef supports a healthy ecosystem. Look into the crevices for Mediterranean moray eels (Muraena helena), often peeking out from their rocky hideaways. Schools of black corbina (Sciaena umbra) can be seen moving gracefully across the reef, and you might spot snapper (Pagrus pagrus) alongside them. While not a pelagic site in the typical sense, barracuda (Sphyraena viridensis) are also present, adding a dynamic element to the schooling fish life.
Navigating Citta Delle Cernie involves exploring the various sections of the seamount. While the primary draw is the main reef, some smaller rock formations exist, particularly to the north. These features offer additional areas to explore, contributing to the feeling of a diverse underwater landscape. It's a site that rewards careful observation, allowing you to discover the intricacies of the reef and its inhabitants.
The conditions at Citta Delle Cernie are influenced by its location within the Strait of Bonifacio. Current here can be variable, meaning you should be prepared for different flow strengths.
