The canal then runs through a tree-lined cutting before entering the 3-kilometre long tunnel. Boats must be fitted with a fixed or hand-held spotlight to pass through, following a fatal accident a number of years ago inside the tunnel itself. Emerging near the village of Créancey the canal begins to drop, passing close to the A6 autoroute, past the villages of Vandenesse and Châteauneuf before meeting the river Ouche at Pont d'Ouche where there are moorings for boats wishing to lay up for the winter. Nearby is the small town of Bligny-sur-Ouche where there is a butterfly museum and a narrow-gauge railway built on the trackbed of a line leading from the mining town of Epinac to loading staithes on the canal. The canal now changes direction from SE to NNE running through the very pretty valley of the river Ouche as it makes its way towards Dijon, the capital of the Burgundy region. On arrival in Plombières-lès-Dijon the canal turns SE passing close to Lac Kir, a man-made lake used for leisure activities, named after Canon Félix Kir, a former mayor of Dijon and after whom is named the white wine and crème de cassis drink known as Kir.
