Grand Union canal towpath. Here the canal enters a tunnel, while the towpath separates, up a slope, through another short tunnel, and then 400 yards later rejoining the canal.Before motors, the narrow boats were propelled through with poles, or with boaters lying on top legging through with feet on the wall. #TowpathTuesday
