Diving Le Roc de Chere
Site Overview
Le Roc de Chere is a wall and altitude dive site in Inland France, France, reached from the base town of Annecy. Le Roc de Chere is an underwater cliff in Lake Annecy, dropping into crystal-clear alpine water at 447 m altitude. Perch, roach and trout patrol the wall, and the visibility is often superb. The site reaches a maximum depth of 25 m with an average profile around 15 m and a shallow start near 3 m, which places it firmly in the beginner category and means divers should hold at least an Open Water certification. Conditions are typical of the French inland freshwater coast: visibility generally runs from 8 to 20 metres, the current is mild, and the water temperature ranges between 8 and 18 degrees Celsius with low surge exposure. The marine community is centred on European Perch, Common Roach, Brown Trout, Arctic Char, Stone Crayfish, Common Rudd, and the full species list is detailed below for divers planning a trip. Le Roc de Chere is a strong representative of why Inland France 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 Inland France 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.
