I don’t know this place and we don’t have recent pictures of this area, so I have to trust you blindly.

But I see that another contributor who changed several paths in this area explicitely added foot=no about one year ago and titled the changeset "Aanpassing toegankelijkheid", which suggests that was for a reason.

Here is what I suggest.

1) https://www.openstreetmap.org/changeset/94230220
Write a comment under his changeset and explain that you’ve been there, and why you think it should be different.  (I don’t know if there are any signs saying it is permitted but that will be a major point, and perhaps the situation has changed recently.)

2) If the mapper replies and that you both agree to change, have anyone of you change the access permissions on the bridleways here.

3) If you cannot do it yourself, write back in this note and we’ll do it for you.
