About ways you marked – it can be a mistake.

I just removed the path next to the river right after this part.

Hi,

We were hiking the trail in September.
We saw some faded signs proving there was a hiking trail.
Unfortunately when we went down, it turned out that there was no path. We spent about 40 minutes to climb back 300 meters. We used maps.me to navigate, which uses OSM.

So I decided to make this change, to help other hikers.
