We climbed it as a three person team. The route was very busy, 10 climbers on it at one time. Best to do it during the week or in the afternoon to avoid crowds. Some placements for .3-.75, 1 sized cams. Used number 8 nut a few times. Only placed 1-2 pieces of gear each pitch.
Climbing for pleasure. Walking back down the 45° Stair of the cable car. If you like take the cable car, you must take a reservation on top and bring some time to wait for getting a free seat. information available on http://www.kwo.ch
