The path was easy to ride in 2024, but the route will probably remain steep. It doesn't look like the former railway line will become a cycle path here, because you can see that there is probably a large bridge missing that leads to the visible old tunnel portal. But once you've got this part behind you, it's just wonderful!
By the way: I think the journey here from the north along the main road is worse than this part (although we went in the opposite direction).
