Diving Le Tombant des Poulains
Site Overview
Le Tombant des Poulains is a wall and reef dive site in Brittany, France, reached from the base town of Belle-Ile. Le Tombant des Poulains is a steep wall off the northern tip of Belle-Ile, dropping into the tidal race between the island and Quiberon. Conger eels, lobsters and pollack hold on the rock while the current brings clear, cold water. The site reaches a maximum depth of 30 m with an average profile around 20 m and a shallow start near 8 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 12 to 24 metres, the current is strong, and the water temperature ranges between 12 and 18 degrees Celsius with high surge exposure. The marine community is centred on Conger Eel, European Lobster, Pollock, Cuckoo Wrasse, Small-spotted Catshark, Corkwing Wrasse, and the full species list is detailed below for divers planning a trip. Le Tombant des Poulains is a strong representative of why Brittany 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 Brittany 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.
