Diving La Gabinière, Port-Cros National Park wall

La Gabinière is a prominent dive site within the Port-Cros National Park, recognized as one of the Mediterranean's most biodiverse marine areas. This site is essentially a dry rock formation with impressive walls and a diverse topography of submerged blocks and rocky scree. Its location within a protected marine park means that the marine life behaves differently from less protected areas, offering a unique opportunity to observe resident species without them being overly shy.

The dive profile at La Gabinière offers multiple exploration options. You can descend along significant drop-offs and explore different sections. The eastern wall is distinct from the southern area, which includes the "Sec" (dry), and the western part of the site. To truly appreciate the site's richness, planning at least three dives is recommended, each focused on a specific zone to understand its unique character and resident fauna.

The site is particularly celebrated for its abundance of brown groupers (Epinephelus marginatus), boasting one of the highest concentrations within the Port-Cros Park. These large, often curious fish are a constant presence, sheltering among the rocky formations. Alongside them, you'll encounter schools of barracudas (Sphyraena viridensis), sometimes dentex (Dentex dentex), and other pelagic species passing by, making for dynamic encounters in open water.

Beyond the larger fish, the walls and rocky landscape of La Gabinière are home to a vibrant community of smaller reef dwellers. Murays (Muraena helena), chapons (Scorpaena scrofa), and scorpionfish (Scorpaena porcus) are commonly seen in crevices. The site features rich invertebrate life, including nudibranchs, various sponges, and impressive expanses of encrusting anemones, which add vivid colour to the rock faces and overhangs.

As you explore the different sections, you'll find diverse gorgonian fields, with both red and yellow gorgonians creating dense underwater forests. Octopus (Octopus vulgaris) are often seen, and if you look closely, you might spot doris dalmatiens (Peltodoris atromaculata) and flabellinas (Flabellina affinis). The rocky formations provide numerous hiding spots, creating a thriving ecosystem for many species, including saddled sea bream (Oblada melanura), bogues (Boops boops), and mullet (Mugil cephalus).

The marine life here is varied and abundant, ranging from small castagnoles (Chromis chromis) darting around the rocks to larger amberjacks (Seriola dumerili) cruising in the blue. Keep an eye out for moonfish (Mola mola), though they are more seasonal visitors. Other common residents include the Mediterranean cardinalfish (Apogon imberbis), wrasses (Symphodus tinca), and occasionally large fan mussels (Pinna nobilis) embedded in the sandy patches, although these are becoming rarer.

The overall experience at La Gabinière is defined by clear visibility and the sheer density of marine life. While the site is a rock with steep drop-offs, the varied topography ensures there's always something to discover, whether it’s the large pelagic schools or the intricate details of the reef system. The sense of being in a well-preserved marine environment is palpable, setting it apart from many other Mediterranean dive sites.
