Reichenau-Schwarzenbach (Jachau) (36,1 km)

It was wet. I rode the route in reverse, but this seems more favorable to me. The trail from Tanneralm is rideable; you may have to lift the bike over the streams, depending on your courage. The hiking path from/to the upper Orterer Alm is definitely not rideable, meaning you have to push the bike unpleasantly. During alpine farming operations, access may not be possible. The path over Rautalm is probably the better option. Despite 'only' about 800 meters of elevation gain, the climbs are tough. The gorges are the highlight, but so is the panorama from Tanneralm. Not much 'traffic' up there.
