re-mapped route https://ridewithgps.com/routes/30260032
a fair bit of off road, so better suited to medium (not narrow) tyred bikes.
surface generally good especially via Fairburn Ings path, but St Aidens can be muddy in wet weather.
Bringing binoculars recommended. For up to date sightings: https://twitter.com/rspbairevalley?lang=en
A 2 café ride – St Aidens and Barwick (Tina's) , with aim of short stops on each reserve for wildlife viewing.
