Kimmage to Harold's Cross, mill by mill. Intro: This walk follows the Poddle past the sites of the mills that once lined it. There are seven stops on a 3 km route, or a short version of under 1 km, including the Stone Boat, the Waterwheel, the weir at Mount Argus and the siphon under the Grand Canal. You get three printable A4 PDFs (14 pages each), one for each class level, with a mill detective table, a walk diary, a certificate and an answer key.
