When planning this trip my biggest worry was the ducks, it turns out the squeezes in the entrance were the hard bits, bruised ribs and they turned out to be quite difficult to return through at least 3. The ducks themselves where not bad, though it's not worth doing the downstream canal. The pretties were awesome but would be destroyed if many people go there. Wellies and gloves off and knee pads reversed. Place trashed my oversuit!
