Please have a look at the discussion in https://www.openstreetmap.org/note/4230307 and Mapillary images from the area. There is no indication visible that access is restricted, which is why I added a `fixme=*` regarding the possibility of private property and didn't modify the `access=*` directly.

As to the area being full of crops, this is seasonal regardless of the crop, the path would be accessible during certain periods of the year. There's lots of cases like this in OSM. The poor trail visibility is also recorded in OSM.
