This path apparently cuts out a huge loop in the Wey South Path.  At the point shown there is a wood, barbed wire and electric fence across it,  I'm afraid we're too old so the lack of clarity on the map led to a wasted detour.

Approaching from the bridges there's an ancient MAFF Conservation Area notice by a (locked but we got through) field gate showing a circular footpath round the field. However only the path marked on the map was at all well trodden so it looks like the through path is used by those who can.  

I don't know what OSM policy on footpaths is, but this one might benefit from some sort of marking to show that there are two paths, and while they obviously meet there is a discontinuity at that point.
