Locks: Canal du Rhône au Rhin (branche sud) Rhin slope 1 - 20

There were originally 41 locks on the north side of the summit leading down to the river Rhine 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 lock (number 1) is now remnants and unfortunately can only be found in the winter when the vegetation dies back.
