About This Site
Lion de Mer is the signature dive of the Saint-Raphael / Esterel sector and one of the richest sites in the Frejus-Saint-Raphael area. A lion-shaped emergent porphyry rock topped by a statue of the Virgin, it offers every kind of Mediterranean underwater landscape from a single mooring: Posidonia seagrass and sandy shallows for beginners, a rocky reef and a natural arch around 8-25 m, and a deep south-facing wall dropping past 40 m. Its highlight is the Grotte a Corail (Voute a Corail), a large vault between roughly 10 and 41 m carpeted in Mediterranean red coral, with the cave proper around 30-33 m. Submerged statues (the Virgin and the Mermaid) sit at 10-20 m near the arch, making the site equally rewarding for a shallow tour or a deep red-coral and wall dive.

Warnings for today

None

An emergent rocky islet about 1.3 km off the Saint-Raphael shore, it drops away on every side but presents its main wall and the Grotte a Corail on the south face toward the open Mediterranean. The mainland and the Esterel massif shelter it through the west and northwest (Mistral) and around the north, while the Maures and Saint-Tropez coast 10-16 km to the southwest largely blocks the Libeccio. That leaves the southern arc open: south and southeast wind-wave (Scirocco, longest fetch) is the dominant exposure, easing off through the east. Diving usually shifts to the leeward lee of the rock when southerly or easterly winds build.
