Unable to answer "What surface does this piece of road have?" for https://osm.org/way/221086278 via StreetComplete 53.0:

I cannot find this footpath (at its western end). There is a high fence with a locked gate where it might start but even afterwards there is not a marked/discernible path but more cross-country trecking relatively steep upwards. Was this maybe copied from Google Maps which also shows a path here?
