Diving Le Rubis
Site Overview
Le Rubis is a wreck dive site in French Riviera – Côte d’Azur, France, reached from the base town of Cavalaire-sur-Mer. Le Rubis is a French Minerve-class submarine scuttled in 1942 as a dive wreck, lying upright on the sand at about 40 m. Its conning tower, hull and propeller are draped in marine growth and shelter conger eels and groupers. The site reaches a maximum depth of 40 m with an average profile around 33 m and a shallow start near 22 m, which places it firmly in the advanced category and means divers should hold at least an Advanced Open Water certification. Conditions are typical of the French coastal coast: visibility generally runs from 15 to 30 metres, the current is moderate, and the water temperature ranges between 14 and 25 degrees Celsius with low surge exposure. The marine community is centred on Conger Eel, Dusky Grouper, Common Barracuda, Common Octopus, Red Gorgonian, Two-banded Seabream, and the full species list is detailed below for divers planning a trip. Le Rubis is a strong representative of why French Riviera – Côte d’Azur diving is so highly regarded, blending the geology, history and biodiversity that define French underwater exploration. It pairs naturally with the other sites of the French Riviera – Côte d’Azur region for a varied holiday, and with the right thermal protection and, where relevant, the correct specialist training, it offers a memorable dive for photographers, naturalists and wreck or reef enthusiasts alike.

Traveler Notes
Who is this for?
Le Rubis suits advanced divers holding at least an Advanced Open Water certification, and it is a strong choice for those who enjoy the French coastal water of the French coast. Photographers, training groups and divers chasing wreck, advanced, deep-dive, history, photography will all find something here, provided they respect the temperature, the marine park rules and the limits of each site. It is less suitable for absolute novices unless booked through a centre running a supervised course, and the deepest or most enclosed sections should only be attempted with the correct specialist training and a guide. Planning a dive here with a licensed French operator not only keeps you safe but also helps protect the fragile gorgonian forests, seagrass meadows, wrecks and reefs that make the site special for the next visitor.
