Les Onze Ecluses (11 locks) along Canal d’ille et Rance. The canal la Rance was designed by the napoleonic time, to link the atlantic ocean to the channel at St Malo. You can walk by the 11 locks along the tow path past pretty little lock houses. We speculated as to how the lock person knows when to come out and let the boat through. I guess if you get there and they are not open the boat wait until it is open. You couldn’t wait in a prettier place.
