A beautiful hike and not too strenuous. While it's still pleasant here in the gorge in summer, it's worth going a little off-season, when it's much quieter.

The Balmfluh castle ruins are clearly visible from the trail. It's worth getting off your bike for a moment and taking a look at the old walls.
