I walked this trail with a good friend in Oktober of 2017. We took the train to the station on Schynige Platte and hiked from there. The views of the Eiger, Monk and Jungfrau are beyond imagine. On the other side, the overlook of Brienzersee is equally stunning, more in the sheerness of the edge. There is a 2 meter section of the trail that narrows on both sides. It was all I could do to make it across. Had a great time and am looking forward to doing more hiking in this gorgeous country!
