Already pretty much at the end/beginning of the railway line, here it is even asphalted, before/later not anymore, but always easy to ride.

An alternative climb to the road with a couple of challenging sections. The condition varies depending on the logging; by 2025, it's suitable for a gravel bike. On the way down, be careful of some water passages.
