I'm off to the inlaws down in Spalding for the Christmas period. I generally have a good walk boxing day, out in Norfolk or maybe the Lincolnshire Wolds. This year I was thinking about a walk to take in some of Northamptonshire's iron workings. Can anyone give me a pointer of somewhere interesting from a surface explore point of view to go. I've got access to os maps for planning a route, but was just wondering what area might be best.
Cheers,
Robin
