The Bärenschultzklamm, takes an hour and half to go through the gorge with it's wooden walkways at a total length of 1.4 km, with 2900 steps, 115 bridges, 49 ladders (never climbed so many in all my life!). Plus it takes 90 minutes hiking to reach the entrance of the canyon, then an hour and 45mins to get down from the top of canyon. So with photographing, video and audio it was whole day with 4 hours driving. Arriving home at 1am.
