We followed NCN 1 from Lincoln to Martin Dales on the form Lincoln to Boston Water Railway Line. The railway lines runs between the River Witham and South Delph. Dotted along the route are various commissioned sculptures and viewing areas. You can see for miles over the fens and waterways. We had a lovely warm afternoon sun to accompany us on our final miles of the day. More information at: sustrans.org.uk/find-other-routes/water-rail-way
