This section of the trail through the forest directly along the shore of Lake Keutschach is a bit more challenging to ride, as it's somewhat winding and undulating on the one hand, and the surface changes rapidly on the other. The trail is generally made up of soft forest floor, but is frequently interspersed with small roots and rocks. Some cycling skill is required for this trail, which offers repeated beautiful views of the lake – but overall, it's a very worthwhile ride.
