and Ancy-le-Franc. The canal passes through the village of Commissey before arriving in Tanlay with its impressive Renaissance château. At Lézinnes boats meet a series of six electrified locks, taking them past a cement works and more grain silos at Pacy-sur-Armançon and on to Ancy-le-Franc. Here the tourist can visit the famous 16th-century château set in its vast grounds. Leaving Ravières there is an extremely difficult pound which suffers from intense growth of aquatic weeds and which can cause fouling of the propeller. Immediately after is situated the small village of Cry-sur-Armançon, site of the Acrobatix Adventure Park. After passing through Aisy the canal enters the Côte-d'Or department. It then runs through Buffon past the great ironwork forge built by the Comte de Buffon in the 18th century. It is then merely a short trip until arrival in the town of Montbard. Nearby is the Abbey of Fontenay. The canal is now running through the wide, flat plain of the river Brenne. Eight locks and 13 km after Montbard the canal arrives in Venarey-les-Laumes situated close to the village of Alise-Sainte-Reine thought to be the site of the Battle of Alesia. At this point the geography changes dramatically. The railway carries on straight towards Dijon, climbing the steep Burgundy escarpment which it crosses by means of a long tunnel at Blaisy-Bas. The canal on the other hand has to divert southwards passing through 40 locks in the space of . It then reaches more friendly ground before the final approach to the summit at Pouilly-en-Auxois. Here there is a large, fully equipped port close to the centre of town. 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
