This 34-km cycle route is a circuit of the East and West Allen Valleys. It is best cycled anti-clockwise. The southern section is part of the C2C Cycle Route and provides an easy link to Allenheads. A shorter circuit is possible, diverting from the main route at Hartleycleugh and crossing Dryburn Moor and continuing down into Allendale. Along this route two chimneys can be seen which are remnants of Allendale's mining heritage. Flues and chimneys formed part of the condensing process, and took fumes from the smelt mills up the valley. Valuable deposits of lead collected within the flues, and periodically small boys were sent through to collect it - not a pleasant job! Please note that the original leaflet was produced and printed in 2005. The routes are still valid but some of the information (e.g. refreshments and facilities) might be out of date.
