The Collancelle vaults and the 16 locks : remarkables sites of the Nivernais canal. On boat, on bicycle or on feet, go to discover these magnificent works of engineering : Collancelle vaults, three galleries dug in the granite to allow the transit of the canal, and the valley of Sardy where the scale of the 16 locks remains an enigmatic place. Do not hesitate to borrow the towpath reserved for the bicycles and the walkers, a pleasant route to enjoy the ambient serenity. However, the boat remains the best way to admire the vaults.
