Le Sec Du Gendarme, Porquerolles: Conical Pinnacle Dive

Le Sec Du Gendarme is a conical rocky rise situated off the Cap des Mèdes, east of Porquerolles. The structure emerges from a vast sandy plain, creating a distinct topographical landmark in the area. Its summit sits between 14 and 16 metres, while the base of the formation drops down to depths of approximately 30 metres. This verticality creates a variety of micro-habitats within a relatively narrow depth range, offering different environments for divers to explore as they descend.

The topography is characterized by a succession of large rock blocks and deep, narrow fissures. These cracks and crevices provide essential shelter for many resident species, making the site interesting for those who enjoy searching through structures. As you move around the pinnacle, the terrain shifts from the relatively flat summit to more rugged, broken sections near the base. This uneven layout means that even a short dive can provide a significant change in scenery and biological density.

The biological life is heavily concentrated on the rocky surfaces of the pinnacle. You will encounter extensive growth of Axinella polypoides and various gorgonians that cling to the vertical faces. Yellow sponges and various anemones also coat the rock, providing a textured backdrop to the site. These encrusting organisms create a complex surface that supports a diverse community of smaller invertebrates and fish, making the physical structure of the rock as important as the depth itself.

Fish life at Le Sec Du Gendarme is consistent with the high-quality habitats found in this part of the Mediterranean. You can expect to see Mediterranean chromis and Mediterranean rainbow wrasse moving in the lighter depths around the summit. Larger, more sedentary species like the dusky grouper and brown meagre are often found patrolling the deeper cracks or resting near the rock blocks. Moray eels and conger eels frequently inhabit the many crevices, watching the area from the safety of the stone.

The site's exposure to the elements is a defining characteristic of the diving experience here. Because the pinnacle stands alone in a sandy area, it is highly susceptible to the Mistral wind. When the wind is strong, the site can experience significant currents that affect both the divers and the boat's ability to maintain a steady position. These conditions mean that the site's character can change rapidly, shifting from a calm exploration to a more demanding technical environment.

Navigation on the site is relatively straightforward due to its conical shape, but the surrounding sandy bottom requires attention. The transition from the hard structure of the pinnacle to the soft sand of the seabed is abrupt. It is important to maintain contact with the rocky features to avoid drifting into the open sandy areas during periods of movement. The combination of the vertical relief and the surrounding flat seabed makes the pinnacle easy to locate once you are in the water.

For those observing the smaller details, the European spider crab and various sea urchins can be found among the rocks and within the crevices. Mediterranean cardinalfish often hover near the sheltered parts of the structure, away from the direct force of the water. The presence of white seabream in the mid-water column adds to the constant movement around the rock. Every section of the pinnacle, from the sunlit top to the shaded faults, offers a different perspective on the local marine ecosystem.
