I reached the Herrenloch via the Hornpfad, which should only be walked uphill due to the danger of rockfall.

A tiny cave that can be reached on the way to or from Balmfluechöpfli via a T5 route. The route is well marked and secured, but sturdy shoes and surefootedness are recommended.

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.
