This single trail leads - starting from Bürenberg - first over a cow mat. And then in the forest very steeply up to the Romontberg. It is flowing and has no major obstacles. A challenge even with the eMTB, but doable. Many a biker will be happy when they have the Romontberg restaurant in sight.
The trail can of course also be used as a downhill trail. When wet, the steep surface could be a bit slippery.
