Situated on the grounds of the Ancaster Old Mill, Upper Mill Falls is a 7m high, 4m wide complex classic plunge which was originally the dam that provided water to the mill. The dam was replaced in 2008, removing many of the natural features and making it look more man-made while reducing the risk of a repeat flooding of the restaurant.
