Locks: Canal du Rhône au Rhin (branche sud) Saône slope 1 - 25

There were originally 75 locks on the south side of the summit leading down to the river Saône but the summit was lowered when the canal was upgraded to Freycinet standard between 1882 and 1904. This standard allowed for barges (péniches) of up to 38 metres in length. The top two locks (numbers 1 and 2) are now remnants and unfortunately can only be found in the winter when the vegetation dies back.
