Frodsham - Marsh Lane, over M56, fork left (Moorditch Lane), mind the pot-holes, after 400 yards take 1st Right up ramp, single track with occasional passing places, along straight for 600 yards then stop before right+left bend & view
Likely other birders/photographers there too; can climb small bank to view better (mind the nettles). Only a few yards to walk. Best viewed when light starts fading
