Discover the Snickleways. Walk the York snickelways, the famous medieval (and later) alleys and narrow streets that thread the center of the city. Try and get hold of a copy of Mark W Jones' book A walk around the Snickelways of York (ISBN 1871125723) or its hardback companion The complete Snickelways of York (ISBN 1871125049) with their quirky, hand-written descriptions. Alternatively walk downstream to the the Millennium bridge, cross and back upstream on the other bank.
