The River Lune Millennium Park and Cycle Way stretches some 15km along the line of the former "Little" North Western Railway branch line that once connected Wennington to Morecambe via Salt Ayre as part of NWR's main line operation between London St Pancras and the Heysham Packet Boat terminal. The stretch of the old railway line between Green Ayre and Bull Beck, Caton, was paved and lit as part of a Millennium project undertaken jointly by Lancaster City Council, Lancashire County Council and The Millennium Commission. Various permanent artworks are to be found along its length and it is worth taking the time to hunt these out (although not all of those originally installed have survived).
This route between Lancaster and Caton is a good way to see some interesting features as well as wildlife on and around the river, throughout the year. There are various points of access to it from the main Lancaster - Kirkby Lonsdale road (A683) if you don't have the time or energy to venture along the whole pathway.
CAUTION: The river bank is steep and slippery here; if you have young children with you, please take extra care when hunting for this cache. There is no need to descend any way down the bank to locate the cache.
Thanks to taurus-littrow for sowing the idea for this cache.
