At about the highest point and almost halfway through the tour, the Kobelalpe invites you to linger, with a great view! Overall, a very nice tour.

The route is marked as an "Alpine Trail" on the hiking signs at the sports center. Just upstream towards Botzenau there were landslides and fallen trees that had to be overcome. The paths, bridges, footbridges, side streams with some waterfalls and stream crossings as well as tunnels and an industrial ruin and bridge ruin make the explorer's heart beat faster. The beautiful landscape does the rest. Warning signs at both ends of the path inform about the risks of sudden water rises, landslides, rock falls, etc.

Shortly after the straight tunnel you can take photos on the rocks with the small rock tunnel in the river.

Generously cordoned off, so that you can only guess at the cave rather than see it. Still impressive.

Sturdy, waterproof footwear with good grip is crucial for navigating uneven and potentially wet terrain. Headlamps are also necessary for visibility in the dark underground environments.
