This is North Mymms footpath 52 which heads through a small wood before entering a field and then crossing the field NNW for 720m until it reaches the side of the A1(M) and continues to steps up to a farm road (location - https://w3w.co/left.wisely.hulk).

  1. Paragraph 5 (last but one line) - I think you turn left, rather than right, when coming onto Tollgate Road for the first time

    1. Thanks Harry, I've made the edit. So glad you pointed it out. Hope it didn't spoil your walk. David

  2. Very pleasant walk with a blend of sunny and shady parts. The railway walk is a source of fascination, especially if you've never seen it before. At the moment some of the fields after North Mymms seem to have been ploughed recently, which slows the pace down, unless you want to sprain something. The footpath at 6-7 strangely enough had a sign with nothing written on it at all, but the directional instructions are so clear that it's hard to go wrong.

    1. So glad you enjoyed the walk, and yes, ploughed rights of way is a problem this time of the year. I love the railway section, too, especially the restored station.
