Short and sweet - the via ferrata at the Hausbach waterfall in Reit im Winkl (difficulty C/ D) makes the eyes light up for everyone who likes to use the via ferrata. The approach from the town center is short and the proximity to the waterfall provides an extra dose of thrill.
A hiking trail has existed in the gorge of the waterfall by the Hausbach river in Reit im Winkl for 100 years. The quite demanding via ferrata has been added more recently.
Incidentally, this was the first via ferrata in the Chiemgau region. The topo is available for download below.
