Diving the Bois Submerge

Site Overview

Bois Submerge is a forest and altitude dive site in Inland France, France, reached from the base town of Annecy. Bois Submerge is a submerged forest in Lake Annecy, where drowned trees stand in crystal-clear alpine water. Perch and trout hover among the trunks, making a surreal, photogenic dive. The site reaches a maximum depth of 30 m with an average profile around 18 m and a shallow start near 6 m, which places it firmly in the intermediate 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 18 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, Brown Trout, Arctic Char, Common Roach, Stone Crayfish, Common Rudd, and the full species list is detailed below for divers planning a trip. Bois Submerge 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.
