I walked along the path here yesterday for the first time.  OpenStreetMap currently makes navigation very difficult.  The map currently contains several walls that don't exist on the ground, and excludes at least one stream.

As currently mapped, the path passes through various walls, some of them real, some not, without gates or stiles.

This area would benefit considerably from careful surveying on the ground supplemented with the details provided by aerial photography to remove confusing or non-existent features and to add significant landmarks such as the stream(s) here.
